Wellue O2Ring Case Study from Dr. Frederico Ribeiro

Wellue O2Ring Case Study from Dr. Frederico Ribeiro

A 75-year-old male patient with Hypertension, Dyslipidemia, Coronary Artery Disease and overweight. He has complaints of Snoring, non-restorative sleep, daytime sleepiness and 2 episodes of lacunar stroke, confirmed with Magnetic Resonance Image.

Initially, while waiting for the polysomnography examination, we decided to monitored the patient’s sleep using the Wellue O2 Ring, a continuous blood oxygenation and heart rate monitor.

Figure 1. Sleep report, generated by the O2 Ring Wellue application, showing 7 hours and 52 minutes of monitoring, 15 oxygen drops in more than 4%, higher oxygen level at 98%, lower at 88% and an average of 94%, getting 1 minute and 24 seconds of oxygen levels below 90%, giving an O2 Score of 8.4. Little heart rate variability, since the patient is on beta-blocker medication.

Figure 2 – Sleep report, generated by the O2 Ring Wellue application, showing 8 hours and 28 minutes of monitoring, 28 oxygen drops in more than 4%, higher oxygen level at 98%, lower at 88% and average of 92%,, getting 26 minutes and 56 seconds with oxygen levels below 90%, giving an O2 Score of 8.3. Little heart rate variability, since the patient is on beta-blocker medication.

Figure 3 – Performed Ambulatory Blood Pressure Monitoring, which showed increased blood pressure loads during sleep, in addition to inversion of nocturnal descent, i.e., blood pressure was higher during sleep. Together with the clinical data with the monitoring of Oxygen and Blood Pressure, we have as diagnostic hypothesis, Obstructive Sleep Apnea Syndrome.

Figures 4 and 5 – Show Polysomnography that confirms the Diagnosis of Moderate Sleep
Apnea, associated with important hemoglobin desaturation with a maximum oxygen
level of 94%, minimum of 77% and an average of 91%, keeping 17% of the time monitored
with oxygen levels below 90%.






Sleep Apnea is the most common type of sleep disorder, affecting about 23.4% of women and 49.7% of men in the general population. American Association of Sleep Medicine guidelines recommend the diagnosis of Sleep Apnea in patients with single-night sleep study with polysomnography in adult patients with suspected disease.

Polysomnography is a technique that makes the graphic recording of multiple physiological variables over sleep time.

Polysomnographic examinations are usually done in specialized laboratories, as the exams are monitored at all times by a trained technician.

Polysomnography, and home sleep apnea test devices provide the apnea-hypopnea index (AHI) and oxygen desaturation index (ODI), both values that present the number of respiratory events per hour used to diagnose sleep apnea and disease severity.

Diagnosing disease with a single test requires high precision of the test method, as well as a stable disease to reduce false-negative and false-positive test results.

However, there is strong evidence of high nocturnal variability of respiratory events in patients with sleep apnea, leading to misdiagnoses and classifications resulting from one-night sleep tests. Undiagnosed and untreated sleep apnea is associated with daytime sleepiness, decreased quality of life, increased risk of accidents, hypertension, cardiovascular events, particularly stroke.


An observational study conducted in the Department of Pulmonology of the University Hospital of Zurich submitted 108 patients with suspected sleep apnea to 14 nights of nocturnal oximetry at home and 1 night of hospital respiratory polysomnography, with the objective of analyzing the variability of clinically relevant nocturnal respiratory events in these patients.

It was found that compared to the results of hospital polysomnography, 1/5 ofthe patients would have been misdiagnosed compared to the test using the pulseoximeter, with a variability of about 3% in the oxygen denaturation index. About 31patients would be misdiagnosed as to the severity of the disease on the first night of theexamination, and by the end of the 13 nights, 83 patients would have been incorrectlyclassified with severe sleep apnea.

The first night of sleep has already demonstrated high sensitivity and specificityof the analyses using the pulse oximeter. Increasing further on a second night of testing.


About 71% of patients would have been diagnosed with sleep apnea on the firstnight, increasing to 88% with an additional night of study, this demonstrates theimportance of performing monitoring for more than 1 night.

Looking at the raw data, it becomes obvious that some of the patients who hadnegative results for sleep apnea during monitoring on the first night, but actuallyshowed positive results during sleep monitoring in hospital polysomnography.

Patients who presented negative results on hospital polysomnography showedvery low oxygen desaturation index values so not even the variability of theseveral-night examination led to a diagnosis of moderate sleep apnea.

Although theaddition of a second night of study significantly increased sensitivity, the negativepredictive value of a recording night was already high. However, it remains debatablewhether a single study showing negative results is sufficient to exclude moderate sleepapnea.

Although the American Association of Sleep Medicine still indicates a single-nightsleep test for patients with suspected sleep apnea, there is an increased risk of false-positive tests. However, the study contradicts showing high specificity, therefore lowfalse-positive rates on several nights of sleep.

Another counterargument againstmultiple night tests is the growing discomfort of this approach, because not all patientsmay be willing to perform repeated night tests in a hospital environment. Alreadyrepeating several nights of examination at home seems reasonable for most patientswith suspected sleep apnea.

In addition to the high cost for the health system to repeatthe examination in a hospital environment, it results in the direct or indirect costs ofuntreated sleep apnea. Studies show that sleep apnea when diagnosed and treated has a positive impact on the economy.

Therefore, as an alternative to expensive and technically complex polysomnography, patients with high probability and lack of relevant comorbidity can be evaluated through portable home sleep apnea tests such as pulse oximetry.

This study revealed considerable nocturnal variability of respiratory events, leading to an identification of a relevant number of patients with sleep apnea who would have been diagnosed or would have the severity of the disease misclassified with the sleep examination performed in a single night.

Especially, patients with lower respiratory event rates were at higher risk of the high variability of respiratory events overnight. Several study nights significantly increased the accuracy of the diagnosis for moderate sleep apnea.

What is IPF? What causes IPF?

What is IPF? What causes IPF?

Idiopathic pulmonary fibrosis (IPF) is a lung condition that scars your lungs and makes it difficult for you to breathe. It’s the most common type of pulmonary fibrosis. 

What does IPF stand for?

• idiopathic = there is no known cause 

• pulmonary = it affects your lungs 

• fibrosis = the name of the scar tissue in your lungs

IPF is a progressive condition. This means it gets gradually worse over time. The scar tissue in the lungs cannot be repaired by the body or any drugs, and there is currently no treatment that stops or reverses the scarring.  

Current treatment focuses on slowing the rate of scarring in the lungs and controlling symptoms. Some people respond well to treatment and find their symptoms remain the same for many years. For others, the symptoms get worse more quickly.   

It’s difficult to predict how quickly IPF will develop because it varies a lot from person to person.  There are no clear stages of IPF, though some people may talk about the mild, moderate, or severe disease. Everyone is different – talk to your specialist doctor about your own situation.

How does IPF affect breathing? 

Scar tissue causes the lungs to become stiffer and to lose their elasticity. This stops them from working properly: they’re less able to inflate and transfer oxygen from the air you breathe into your body. 

Each time you breathe in, you take in air through your nose and mouth, down through your throat, and into your windpipe (trachea). Your windpipe splits into two main tubes, the right and left bronchi, which supply your lungs with air. 

The main bronchi divide into gradually smaller airways called bronchioles. Bronchioles have many small air sacs (alveoli) at their ends. Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels and into your blood. The air sacs also exchange waste gas (carbon dioxide) from your blood ready for you to breathe it out. 

If you have IPF, scarring affects the air sacs, eventually limiting the amount of oxygen that gets into the blood. With less oxygen in the blood, you can get breathless from everyday activities like walking. 

What causes IPF?

Idiopathic means the cause is not known, but researchers now believe that the body creates fibrosis (scarring) in response to an injury to the lung. 

The initial injury to the lungs might be from: 

  • acid reflux from the stomach 
  • viruses – in some studies, IPF has been linked to certain viruses, including herpes, hepatitis C and the Epstein Barr virus, which causes glandular fever 
  • environmental factors – breathing in certain kinds of dust from wood, metal, textiles or stone, or from cattle or farming  
  • cigarette smoke exposure.    

It is not known if these factors directly cause IPF. 

Some people may also get IPF if it’s in their family history. But this link is only found in a minority of cases. According to a 2021 survey by the British Thoracic Society, 5.7% of patients were found to have a known relative with IPF. 

Who gets IPF?

 IPF is more common in people over the age of 40. It is also more common in men than it is in women.

Symptoms of IPF

The first symptom you might notice is getting out of breath when you’re doing everyday activities like walking up the stairs. 

The main symptoms of IPF are:  

  • breathlessness 
  • a cough that doesn’t go away 
  • feeling tired all the time 
  • clubbing of the fingertips or toenails.

If you have IPF you may feel short of breath a lot, and not just when you’re moving about. If you feel breathless you should visit your GP. 

A cough that doesn’t go away (usually a dry cough ) and feeling tired are other symptoms of IPF. 

You may also notice clubbing of your fingertips or toenails. This means the shape of your fingers or toes might appear like a drumstick, with the tips being larger around the nails. The base of the nails may also feel spongy. Having this doesn’t mean you have IPF as it can occur in other conditions too. But check with your GP if you notice it developing. 

How is IPF diagnosed?

A team of several experts (called a multi-disciplinary team), often at specialist hospitals, will collect information about you before making a diagnosis. This is because there are many types of pulmonary fibrosis.  

IPF is one of many different types of pulmonary fibrosis. This means diagnosing IPF will involve a lot of tests to rule out the other types of pulmonary fibrosis. Your doctor is likely to listen to your chest and ask about your family, medication, work, and medical history. You may also have blood tests to rule out other causes of your symptoms. 

If you have IPF, doctors listening to your chest can often hear crackles in your lungs that sound like Velcro opening.   

You may need tests such as: 

  • a CT scan to produce a detailed image of your lungs
  • breathing tests, such as spirometry, to measure how well your lungs are working
  • a bronchoscopy to see inside the lung and get samples of the lung tissue – this is done using a small tube with a camera
  • a lung biopsy, where tissue or cells are taken from the lung for testing. 

IPF sometimes shows up as a honeycomb pattern on the lungs in a CT scan. The image shows lots of empty pockets or bubbles appearing where more solid-looking tissue would normally appear.  

Being diagnosed with IPF might feel overwhelming at first. It can help to talk to your family and friends about it. You may want to read our information about looking after your mental health too. 

Treating and managing IPF

Treatment for IPF aims to slow the rate of scarring in the lung and treat the symptoms. 

Medication to slow the scarring

The importance of self-care 

You should be treated at a specialist clinic, or by a team that comes to your local hospital. You should have regular appointments every 3-6 months.  

Lung transplant

If the IPF gets worse in spite of treatment, a few people might have the option of having a lung transplant. Your specialist team should discuss lung transplant with you within six months of your diagnosis if it’s suitable.   

Supportive treatment

Treating the symptoms rather than the cause of a disease is called best supportive care. Your doctors may discuss pulmonary rehabilitation to help with your symptoms of breathlessness and oxygen therapy to help maintain oxygen levels to other organs. 

Your doctors may also discuss palliative care – this is a plan to help you through any stage of a life-limiting illness and focuses on improving symptoms of the condition. 


Your doctor will look for and treat problems that could be making your coughing worse, such as heartburn (acid reflux) or a blocked nose. Your doctor may also be able to refer you to a physiotherapist who can suggest ways to manage your coughs, such as sipping water or swallowing. 

Severe coughing can often be suppressed with low doses of liquid morphine. It is usually given by syringe into the mouth and works quite quickly. There are potential side effects of morphine, so your doctor will discuss these with you before you decide if you want to take it.   

If you find it difficult to cough up mucus, you may be prescribed medicine such as to help loosen and thin mucus in the lungs. Some people find it helps their cough, but others may experience side effects such as stomach discomfort, trapped wind, or feeling sick.   


To help you cope when you get out of breath, pulmonary rehabilitation is an important treatment and you’ll learn breathing techniques so that you feel more in control. 

IPF can cause the level of oxygen in your blood to fall. This can make you feel more breathless. If this happens, you may be prescribed home oxygen treatment to allow you to be more active. 

For more severe symptoms of breathlessness, which can sometimes make you very anxious, your doctor might recommend low doses of a short-acting medication such as lorazepam which can help take away sensations of severe breathlessness and panic. These tablets dissolve under your tongue.

Monitor the effectiveness of your therapy

Wellue O2Ring Blood Oxygen Monitor

Acid reflux

Tell your doctor if you have symptoms of gastro-oesophageal reflux, such as heartburn, indigestion, or a sour taste at the back of your mouth. There’s evidence this may make IPF worse and make a cough worse. You can have treatments that reduce the amount of acid your stomach makes, such as omeprazole. Liquid antacids such as Gaviscon can also be helpful in preventing reflux at night.

Sometimes acid reflux is caused by a Hiatus Hernia, and this can be more common in those with IPF.  


You might feel anxious or even depressed when living with a long-term, progressive condition. Talking about your concerns with your medical team, friends and family can be helpful. But some people may also need medication or other therapies to help improve their mood. Don’t be afraid to ask if you or your family member needs help to improve their mental well-being.

The importance of self-care

It’s important to look after yourself to stay as well as possible if you have IPF. 

If you smoke, the best thing you can do for your health is to quit. 

Exercise as often as you can to stay fit. This can also help to improve your mood. 

Eat a healthy, well-balanced diet.

Try to get enough sleep

Try to keep away from people who are ill with coughs or colds. 

Why You Need Pulse Oximeter With CPAP Therapy

Why You Need Pulse Oximeter With CPAP Therapy

When you were diagnosed with sleep apnea, you had your sleep study. As you know, they kept track of your blood oxygen level, but they also measured many other values: pulse, blood pressure, number of apneic episodes per minute, amount of REM sleep, etc. The purpose of the CPAP machine is to overcome the obstruction caused by your airways and allow you to keep breathing at a regular rate throughout the night.

Since CPAP therapy should directly affect your oxygen intake, you need a way to monitor your blood oxygen levels. Here’s why you should pair your machine with an oxygen monitor

What is a Fingertip Pulse Oximeter?

Firstly, let’s describe a pulse oximeter and how it functions.  A pulse oximeter, most often worn on the fingertip, is a medical device that measures oxygen saturation levels in a person’s blood.  In other words, it measures the amount of oxygen present in the bloodstream.  It is typically for people who have the potential for unstable blood oxygen levels like those that are already in intensive care units and emergency rooms.  The finger pulse oximeter uses red and infrared light to measure the oxygenation in the fingertips. 

How is this possible? Because Hemoglobin (the part of the blood that transports oxygen) absorbs different amounts of light depending upon how much oxygen it is transporting. 

Why is Blood Oxygen Level Important?

Low blood oxygen levels are harmful for many reasons.  But let us consider how blood oxygen relates to sleep apnea and CPAP therapy.  Low oxygen levels certainly may indicate a serious health problem.  People with sleep apnea or an underlying lung disease such as asthma or COPD, sometimes have blood oxygen that drops to unhealthy or even fatal levels.  When people suffer from sleep apnea, their airways close and oxygen does not flow to the brain and bloodstream.  Oxygen levels then fall, triggering the brain to arouse the body.  Although this happens subconsciously, the body continually awakens negating the positive benefits of deep and restful sleep.  This vicious cycle is the typical symptom of sleep apnea.  A pulse oximeter can read oxygen levels to help to confirm a diagnosis of sleep apnea.

Using a Pulse Oximeter with CPAP

Once you have been diagnosed with sleep apnea and are using your CPAP/APAP/BPAP machine, it is important to confirm you are receiving the full benefits of the therapy.  Of course, the reason behind using a PAP machine is to maintain the integrity of your airways in order to breathe normally and deliver oxygen to the bloodstream. 

A pulse oximeter can supplement any software available with your PAP machine by measuring this important gauge of the effectiveness of your treatment.  Simply attach the pulse oximeter to your fingertip and let it record your blood oxygen levels.  There are, of course, nuances that need to be users need to understand when reading the results such as how much time you spend at certain low levels.  But overall, it will give you a barometer for keeping CPAP therapy as is or speaking to your doctor about optimizing.

Many CPAP users are interested in using pulse oximeters as part of their ongoing CPAP therapy.

How to choose the best oximeter to help with PAP treatment?

Data from a pulse oximeter can be used to check two important pieces of information – heart rate, and blood oxygen saturation percentage. In sleep apnea patients, the heart rate generally increases and the blood oxygen saturation level generally decreases during apnea events. A pulse oximeter with recording capability worn during sleep can help a CPAP user know if their CPAP therapy is effective. Unfortunately, even the most advanced CPAP machines do not record this type of information.

Here we’re going to summarize the features you should look for in a pulse oximeter, so you can make an even more informed purchasing decision.

Long-Term Recording vs. Spot Checking

This is the biggest difference you’ll find in pulse oximeters. A recording pulse oximeter allows the user to wear the device for hours at a time, and then look at the recorded data later. If you have sleep apnea and if you want to see what’s going on at night when you sleep, then you’ll need to select a model that has recording capability. If, on the other hand, you’re looking for a device for periodic spot checking only, then either type of oximeter would be suitable.


The pulse oximeters with recording capability have built-in alarms that allow the user to set thresholds at which the alarms will sound. In addition, these devices also have a low battery alarm. Alarms can be useful in many activities to let you know that you’ve exceeded your desired heart rate, or that your blood oxygen level has fallen below a pre-determined level.

Comfort Wearing

Almost all fingertip oximeters will feel pretty much the same when applied to a finger. The clamp-like alligator clip design is ubiquitous. Many people need to switch fingers after a couple of hours. A more comfortable option is the wearable Pulse Oximeter. They are usually designed in a ring or wrist-wearing shape to fit the user’s fingers and wrist. Not easy to slip during night-wearing, in addition, the silicone material also ensures long-term comfort.

Perfusion Index

The perfusion index is a relative value that indicates the strength of the pulse at the sensor site. The perfusion index is commonly used to help identify appropriate sensor application sites. This means that you can use the perfusion index to determine where you’re getting a good reading. You can move the oximeter from one finger to another to see if there is a difference in the perfusion index. It’s a good idea to place the oximeter where the perfusion index is highest. The perfusion index can also help to identify any anomalous readings during recording. If you see data that looks inaccurate it could be due to temporary incorrect positioning of the sensor on the finger. A low perfusion index value corresponding to the “bad” or “artifact” data can help you determine the true nature of the data.

What Our Customers Are Saying

  • Wearing one of the O2ing each night has kept me afib free for nearly three years now. I have central sleep apnea and would end up in atrial fibrillation every 2-3 months when I’d stop breathing while sleeping. This ring vibrates when my O2 level drops too low and that’s enough to get me to breathe again! And it’s helpful to look at the app on my phone each morning to see how I did the night before. CPAP machines are only marginally effective for central sleep apnea and there are no other treatment options, but this is the closest thing and has been very effective for me.
  • Excellent compliment to CPAP Machine. It does Not tell you when you STOPPED BREATHING, it will give you an accurate record of your Sp O2 oxygen/saturation ratio. The phrase stopped breathing is misleading. Some people have a lifelong breathing rate which includes a pause between breaths, whereby the Sp O2 drops off to a point that may be alarming to some. If you are fatigued throughout the day, it may be the result of lack of oxygen when sleeping, and sometimes during waking hours, leading to a more serious health risk. This is a wonderful piece of equipment which will assist you and your doctor to make an assessment of your health. The Vibration is felt when the oxygen saturation drops below a level that you preset. If you consciously take a few deep breaths the oxygen level comes up again, sometimes changing your sleeping position will help. With Covid lurking around every corner it is wise to know your SP O2 level. This light weight, compact, easy to use equipment is a great companion to a CPAP machine. I print out a hard copy of the previous nights sleep each morning, and can see when my SP O2 dipped below my preset level. I also use a Smart Watch which features SP O2 and Blood pressure at a glance at any time day or night. The Getwellvue Ring Finger Oximeter is the only monitoring device I have which will give me a minute by minute chart and graph of my SP O2. It is a very helpful piece of equipment.
  • I own two rings because I won’t go to sleep without it anymore. If I slide down down from the really neat foam wedge set that keeps me elevated and apnea starts, the ring vibrates to wake me up so I can re-adjust my position and get some O2 back into my body.
  • I love my ring! Having a constant reading allows me to adjust my oxygen as needed. It also alerts me when my cannula falls off while I’m sleeping. A vibration warning is so much better than waking up gasping for breath!
Is Ultrasound Necessary for the Pregnant Dog

Is Ultrasound Necessary for the Pregnant Dog

Dog pregnancy can be confusing and stressful. In general, the average period of canine pregnancy will last about 2 months. However, it is difficult to predict the timing of delivery because the breeding date doesn’t always match up with the conception date and the gestation period in dogs varies with breed and litter size. Thus, it is necessary to use some diagnostic tools for dog pregnancy confirmation. Then someone asks: is ultrasound necessary for a pregnant dog?

Pregnancy Test in Dogs

Diagnostic testing is the most accurate way to tell if a dog is pregnant.

#1 Ultrasound—the most reliable way

Ultrasound is a non-invasive technology widely applied both in veterinary and human medicine. The ultrasound probe records echoes of ultrasonic waves that are transmitted through the dog’s body to create an image. Ultrasound scanning is most often utilized with pregnant pets to gauge the health of puppies and kittens because abdominal ultrasound allows veterinarians to have a closer look at the internal organs. The owner of the puppy mill really should get the dog scanned for pregnancy with a vet ultrasound.

The Advantage of Ultrasound for A Pregnant Dog

There are many reasons that ultrasound is thought to be the most reliable way of evaluating canine pregnancy. One of the key advantages of ultrasound is that it offers a real-time look at the internal organs of those dogs. Other benefits of ultrasound for pregnant dogs include:

  • Non-invasive, pretty safe for pregnant dogs.
  • Require no necessary medication or anesthesia.
  • Great efficiency. The procedure won’t distress dogs.
  • Allow viewing the internal organs with greater precision.
  • Affordable.

Dog Pregnancy Confirmation

Ultrasound for a pregnant dog is best done 20-30 days after breeding. It is helpful to distinguish between pregnancy and pyometra.

As the best method used to visualize and evaluate the pups in the womb, ultrasound scanning won’t cause radiation exposure to the developing fetuses. It is pretty safe for puppies. However, it is less accurate to estimate fetal numbers because only a small portion of the uterus can be imaged in one view, and some fetuses may be double counted and others not counted at all.

Assessment of Fetal Viability

Ultrasound is a useful tool for the assessment of fetal viability, fetal malformations, and fetal distress. It can provide useful information for monitoring fetal growth for accessing gestational. Veterinarians can access the fetal heart rate and fetal movement with ultrasound probes.

It has been reported that normal fetal heart rates are 180-245 beats per minute in dogs. If the fetal heart rate is discovered less than 180 beats per minute and the fetal bowel movements are found by the ultrasound, severe fetal distress may happen. Ultrasound is important to implicate for managing clinical assistance and planning.

The Role of Vet Ultrasound in Canine Dystocia and Stillbirths

Canine dystocia or stillbirth can seriously harm the mother dog if it cannot be detected and managed as early as possible. It will cause uterine diseases, such as endometritis or pyometra. Also, canine dystocia or stillbirth may affect the dog’s next conception and even endanger her life. Therefore, early diagnosis of dog pregnancy is very necessary. Vet ultrasound is one of the most common methods of confirming dog pregnancy. And doppler ultrasound is a useful method for assessing the development of the placental and fetal circulation during normal and abnormal canine pregnancy.

If there is a substance with a slightly strong echo in the fluid that is found in the uterus of the pregnant dog, and the vertebrae and part of ribs can be vaguely discernible, but no heart beating can be seen, then the canine stillbirth can be confirmed.

#2 Relaxin Test

The Relaxin test, also called a hormone test, is a blood test to detect dog pregnancy by measuring levels of a hormone called relaxin. The hormone relaxin is only produced during the dog’s pregnancy and will decline following the end of the pregnancy. At about 25-30 days of gestation, the veterinarian can perform this test to confirm the dog’s pregnancy.

#3 Abdominal Palpation

By gently pressing on the surface of the dog’s abdomen with fingers, you can feel swellings in the uterus. Abdominal palpation is the traditional way of detecting pregnancy in a dog. This test must be careful, otherwise, it will damage the puppies. In addition, abdominal palpation is not reliable for determining the viability of the fetus.

#4 X-ray

Abdominal X-rays are useful in detecting dog pregnancy, but this is best done in the last trimester of gestation, as the puppies’ bony structures cannot be seen until then. However, dog stillbirth in the uterus would be difficult to detect on X-ray.



Come back to the question: is ultrasound necessary for the pregnant dog?

Ultrasound is not necessary for dog pregnancy because there are several other ways like relaxin test, abdominal palpation and X-ray to tell if a dog is pregnant. But ultrasound scanning is the most reliable way of detecting pregnancy and accessing the viability of the fetus.
