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 one wearable in our partner clinics, local stores, or distributors. Or leave us a message, and we will contact you for personal arrangements.


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.

根據臨床研究結果顯示,血氧濃度下降指數或血氧飽和度指數 (ODI) 與呼吸中止指數(AHI) 具有高度相關性[1],因此醫療機構在判斷睡眠呼吸中止的數據上,即以ODI 作為AHI的參考或初步篩選的重要依據[2]。ODI可分為ODI3% 與 ODI4%,分別是透過配戴的血氧儀,紀錄血液含氧量(SpO2%),在根據睡眠缺氧的事件,計算出每小時血氧濃度下降 3% 與 4% 的次數。而另一組與血氧濃度相關的參數T90/T89/T88 [3][4],定義為睡眠期間 SpO2 < 90%/89%/88% 的累積時間(百分比)。根據研究文獻 [5][6][7],依據ODI3%,ODI4%,T90,T89 和 T88 等參數是初步篩查睡眠呼吸中止症的良好工具。
