Review on 📱 Oxylink Remote Sleep Monitor with WiFi Stick for Real-time Monitoring - Bluetooth, HR Tracker, Audible Reminder, Portable - Ideal for Adults, Rechargeable - Free APP by Kevin Campos

First of all, this device is very expensive and you should find out if your healthcare program or the FSA will cover the cost of it, making it much more affordable. Functions:=Constantly monitor blood oxygen saturation, heart rate and body movements=Acoustic reminder in app and device for low blood oxygen=App with unlimited storage=Sp02 and heart rate data transferHere is a function to share this information with your family or doctor, but Of course only with people who are entrusted with your personal health data. Pros = Detects hypoxia when CPAP mask is removed (via alarm) = Alerts when O2 is below a set limit = App supports graphs and results, especially long term (see photos) = Doctors can distribute to patients and monitor at home (but not all at once) = Alerts caregiver to abnormal O2 levels = Alarm will continue until you turn it off, even if you sleep through multiple alarms = Great tool for sleep apnea = Both phone app and device sound (to monitor two people) Cons = Price = Rather clunky monitor = Cannot set alarm to heart rate (correct me if I'm wrong)
