This study tested whether different pulse oximeters give the same blood flow readings in 42 healthy adults. Researchers compared measurements at rest, during movement, and when blood flow was restricted. The goal was to see how much the device itself affects the reading, not to t…

This study compared blood oxygen measurements from three different smartwatch brands against a standard medical pulse oximeter. 18 healthy adults participated, and researchers looked at how closely the smartwatch readings matched the medical device. The goal was to see if smartwa…

This study tested 24 healthy adults to see if the finger chosen for a pulse oximeter sensor changes oxygen level readings during brief low-oxygen and high-carbon-dioxide conditions. The goal was to find out if finger choice affects accuracy, which could help improve diagnosis. Re…

This study looked at how breathing low oxygen (hypoxia) and high carbon dioxide (hypercapnia) changes heart function in healthy people. Fifteen volunteers took part in short breathing experiments. The goal was to understand these effects, not to treat any disease.
