You are sleeping and dreaming about unicorns, but do you know that your breath may stop and there may be a lack of oxygen in the blood, and you may be suffering from obstructive sleep apnea (OSA). Since normally people do not really experience symptoms, just wake up tired and feel sleepy during the day, it is not easy to detect it in its first phase.
Yet at least one in five adults who snore suffer from OSA in the US, usually, sleep apnea patients are surprised when they are diagnosed with this condition. Their airways are temporarily closed, preventing breathing, and they breathe less oxygen. These apneas can happen hundreds of times per night, apnea might even generate hypertension, heart disease, brain attacks, or diabetes.
The SleepU sleep oxygen monitor is designed for snorers and people suffering from OSA. It tracks your blood oxygen and heart rate level as well as your body movements. It can tell whether it is worth investigating sleep apnea further with a health professional. This is cost-effective, whereas diagnostic tests require overnight stays at a sleep lab and can cost thousands of dollars. Using SleepU can prevent you from making those unnecessary trips to a sleep lab, or alert you to the fact that you may need to visit them. Its adjustable vibration alert in the patented ring sensor will nudge you to change position to let you breathe more oxygen and sleep better.
The SleepU is USB disk-sized and equipped with a ring sensor to track blood oxygen level and heart rate. Unlike other fitness wearables tracking blood oxygen levels as part of a more extensive feature, SleepU exists solely to monitor your sleep blood oxygen. It is transmissive oximetry and measures blood oxygen level with medical-grade accuracy, whereas other wearable fitness devices utilize reflectance pulse oximetry. Usually, hospitals use transmissive oximetry, and this is where SleepU sets itself apart from main consumer-oriented sleep tracking devices.
How can you benefit from smart vibration?
SleepU has a unique design with a vibrator built in its ring sensor rather than the main unit, which makes it suitable for whole night’s sleep. When your blood oxygen level drops below your preset level (e.g. below 90%), the ring sensor will vibrate and stir you to wake up gently, remind you to change your position, helping you to reopen your airway to reduce snoring and breathe more oxygen.
If you are reluctant to wear a ring on your finger in bed because you consider it will disturb your sleep, I have to tell you that the SleepU sleep oxygen monitor is soft and comfortable to wear on. Since other devices usually cover your whole finger, oppressing your finger, making it numb and sweaty, and are easy to fall off from your finger, SleepU feels like wearing nothing.
The silent vibration instead of audible beeping doesn’t disturb your partner. You can adjust vibration intensity and threshold in App to fit you best. So the smart vibration function is useful for everyone, but it is especially useful for people who snore and those who have to live with sleep apnea, as well as their partners who sleep with them.
Is my CPAP machine effective?
SleepU tracks SpO2 and heart rate overnight, it helps you to see whether the CPAP machine or oxygenator is effective and provides more info for therapy.
How to operate?
Simply wear it on your wrist overnight, no need to press a button, it records O2 saturation and heart rate automatically. No need to connect with your phone as it works even when not connected: 4 sessions will be stored in the device while the data will sync once it is connected. Absolutely, you can also connect SleepU with your smartphone or tablet while using, to watch your real-time SpO2 and heart rate.
Sleep insight with ViHealth APP
The next morning, you wake up, take off the device and enter the ViHealth APP to view the detailed report. You will see your overnight blood oxygen level, how many times your oxygen drops, how long your oxygen is below 90%, heart rate, body movement, and O2 score. O2 score is an easy and simple index to tell if your SpO2 is healthy while sleeping. It is calculated based on the drop time and how severe it drops, the higher the better. You can also log notes to record your comments, such as lifestyle or therapy. Or share overnight oximetry data and trends with doctors or friends for advice.
Share PC report with a doctor
With the included cable, you can connect the device to your PC or laptop, upload your overnight oximetry data to the PC software, export sleep report, save it as PDF or CSV format, share unlimited reports to your doctor or friends, and it is totally free!
Take it everywhere with you
SleepU is USB rechargeable, working up to two nights on one charge. It can not work for a week like other fitness or sleep tracker, as the ring sensor continuously tracks your overnight oxygen saturation every second, that’s to say it will not ignore your blood oxygen event per second. As we know, their founders have over ten years of experience in medical device R&D.
If you suffer from snoring or sleep apnea, and you are tired of others constantly reminding you of it and giving you silly pieces of advice on how to deal with it, you should certainly consider trying the SleepU sleep oxygen monitor. As the device is certainly the most convenient tracker for measuring SpO2 during sleep.
