Rio De Janeiro: A new study has revealed that 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 observed “strong positive correlations between the Apple Watch device and commercial oximeter”, reports 9To5Mac.
There was no statistical difference in the evaluation of skin colour, wrist circumference, presence of wrist hair, and enamel nail for SpO2 and heart rate measurements in Apple Watch or commercial oximeter devices”.
100 patients with chronic obstructive pulmonary disease and interstitial lung disease from an outpatient pneumology clinic took part in the study.
It collected SpO2 and heart rate data with Apple Watch Series 6 and compared them to two commercial pulse oximeters.
Healthy individuals, people with Interstitial lung disease (ILD) and with chronic obstructive pulmonary disease (COPD) underwent the tests.
Strong positive correlations between the Apple Watch Series 6 device and commercial oximeters.
The Apple Watch has a tendency of higher SpO2 values than commercial oximeters. However, heart rate measurements were similar in both devices.
The study didn’t observe significant differences between the Apple Watch and commercial oximeter devices..
Overall, the study said that “despite a tendency to present higher values when compared to conventional oximetry devices, the Apple Watch device was accurate and similar” although it’s important to note that results were made “under controlled conditions”.
