Pulse oximeters, a type of photoplethysmography (PPG) sensor, are electronic devices that measure a person’s blood-oxygen saturation (SpO 2) and heart-rate (HR) levels. Since their inception in the ...

However, the traditional method of transmission pulse oximetry (TPO) has several limitations. In conditions of poor peripheral perfusion or cardiovascular collapse, the measurements of this method are ...

Pulse oximetry is a means for non-invasive monitoring of oxygen saturation in blood. It employs an indirect method of assessing these conditions immediately just by clipping a sensor onto your finger ...
