The blood oxygen sensor featured in Apple Watch Series 6 and 7 is “not intended for medical use,” Apple says. That seems odd, considering that low blood oxygen is a serious medical condition. If the ...

Normal blood oxygen level is either 95%-100% SpO2 on an oximeter or 80-100 mm Hg from an ABG test. ABG tests are more accurate than pulse oximeters, which have a ...

A dangerously low oxygen level—usually below 92%—can cause shortness of breath, confusion, chest pain, or fainting. It’s often triggered by lung or heart conditions like COPD, asthma, or heart ...

A pulse oximeter is a small device that can measure the oxygen saturation in your blood. Pulse oximetry is useful for people with chronic lung or heart conditions, who need to monitor how well oxygen ...
