A new study published on Scientific Report, an online multidisciplinary, open-access journal from the publishers of Nature, shows that the Apple Watch Series 6 “is a reliable way to obtain heart rate and oxygen saturation (SpO2) in patients with lung diseases under controlled conditions.”
The study from the University of São Paulo, one of Brazil’s more prestigious education institutions and was conducted with 100 patients with chronic obstructive pulmonary disease and interstitial lung disease from an outpatient pneumology clinic. It collected SpO2 and heart rate data with Apple Watch Series 6 and compared them to two commercial pulse oximeters.
The study observed “strong positive correlations between the Apple Watch device and commercial oximeters. It notes that “there was no statistical difference in the evaluation of skin color, wrist circumference, presence of wrist hair, and enamel nail for SpO2 and hear rate measurements in Apple Watch or commercial oximeter devices.”
