Background: Apple watch validity to measure the heart rate (HR) and oxygen saturation (Spo2) in healthy subjects has been investigated, but its accuracy and validity for patients with chronic non-communicable diseases such as diabetes mellites (DM), hyperlipidemia and hypertension (HTN) is still unclear. Patients with chronic diseases as DM, HTN and hyperlipidemia who have hypoxemia are advised to continuously monitor their Spo2. Therefore, this study aims to investigate the accuracy of the Apple watch in measuring the Spo2 and heart rate in patients with chronic diseases. Method: A cross sectional study will invite ninety-five patients with chronic diseases to participate in this study and the eligible participants will be allocated into three groups. The first group (Group-A) will include patients with the DM, the second group (Group-B) will include the patients with HTN and the third group will include patients with hyperlipidemia. All participants will use the apple watch to evaluate the Spo2 against the pulse oximeter at rest. The main outcome will be the Spo2 and heart rate that will be evaluated at rest and before and after exercise for 15 minutes using the Apple watch, Spo2 and Polar HR monitored using the pulse oximeter.
