The simple, remote, and affordable sleep health monitoring platform.
By using ZionCare platform, you can sleep in your own bed comfortably for multi-night evaluation and wake up with lab-quality test results capturing internight variability.

What is ZionCare?

ZionCare is a platform that collects medical-grade patient data for sleep health monitoring. It allows clinicians to deliver a higher quality of care to more patients and avoid unnecessary in-person visits for patients. It is recommended by leading somnologists, sleep specialists, and clinicians and used by people worldwide for accurate oxygen saturation (SpO2) recordings.

ZionCare Wearable

Wearable pulse oximeter

It is designed for continuous blood oxygen level, pulse rate, and respiratory rate monitoring at your wrist without a traditional fingertip probe.

  • Oxygen Saturation: 70~100%, +/- 3%
  • Pulse Rate: 40~240 bpm, +/- 3 bpm
  • Respiratory Rate: 4~40 rpm, +/- 1 rpm
  • FDA-cleared in TW, US and AUS
  • CE Mark Certified
ZionCare Web Portal

ZionCare Web Portal

It is a HIPAA compliant web-based portal that gives clinicians access to monitor their patients’ oxygen saturation, pulse rate, and respiration rate remotely anytime, anywhere. The continuous monitoring of big data helps to support clinical decision making.

ZionCare App

ZionCare App

It is a user-friendly app that turns complex sleep health test results into visual and easily understood data for self-check.

How it works?


Pick-up the wearable

You can pick up a wearable device at one of our partner clinics, stores, or dealers, or click the button below to participate in the sleep hypoxia detection program.


Sleep as usual

Download ZionCare App and complete registration. Sleep at your own bed as usual with the wearable on.


Quick analysis & treatment

You can check your sleeping data on ZionCare App after sync-up. Your doctor can review it on ZionCare web-portal and recommend treatment options.



You can continue to monitor your sleeping data using our ZionCare platform and discuss with your doctor on your treatment progress for continuous improvement.

ZionCare App


The sleep analysis records include oxygen saturation, pulse rate, and respiratory rate data during your sleep and these data are used to calculate key indexes like ODI (Oxygen Desaturation Index), T88 (percentage of cumulative time during sleep with oximetry below 88) to detect sleep apnea.


Various trend charts will help you to track your conditions, symptoms, and treatment progress capturing internight variability.


Send your professional report (in pdf) to your doctor, sleeping specialists, or your family members to keep them informed on your sleeping condition.

ZionCare SpO2 Classification During Sleep


Normal: ODI 3% < 5
The number of oxygen desaturation drop per hour of sleep is in the normal healthy range.


Mild: 5 ≦ ODI 3% <15
The number of oxygen desaturation drop per hour of sleep is slightly higher, please continue to track and observe.


Moderate: 15 ≦ ODI 3% <30
The number of oxygen desaturation drop per hour of sleep is higher than the standard range, it is recommended to consult a professional doctor.


Severe: 30 ≦ ODI 3% or T88 ≧ 3%
The number of oxygen desaturation drop per hour of sleep or the cumulative time with low oxygen saturation is much higher than the standard range, it is recommended to seek further diagnosis by a professional doctor immediately.

The current gold standard method for sleep apnea assessment is fully-night polysomnography (PSG) and apnea-hypopnea index (AHI) is the most widely used parameter derived from PSG. Based on clinical trials, the oxygen desaturation index (ODI) has a very high correlation with the AHI [1], therefore medical institutions use ODI as a reference for AHI or as an important basis for preliminary screening sleep apnea [2]. ODI can be divided into ODI3% and ODI4%, which are respectively calculated as the number of episodes of oxygen desaturation per hour of sleep, with oxygen desaturation defined as a decrease in SpO2 (recorded by pulse oximeter) to lower than 3% or 4% below baseline. Another set of parameters related to SpO2 is T90, T89, and T88, which is defined as the cumulative time (percentage) of SpO2 < 90%/89%/88% during sleep. According to various research studies [3][4][5], parameters such as ODI3%, ODI4%, T90, T89, and T88 are key indicators for screening sleep hypoxia.
