Nettet8. jun. 2024 · Greater resolution in the PPG measurements will reduce the uncertainty in the SpO 2 algorithm. With a typical PI of 1% to 2% for wrist-worn SpO 2 sensors, the goal of pulse oximeter design is to increase the PI through mechanical design or to increase the dynamic range. The spacing of the LED to PD will have a major effect on the PI. NettetWhat is pulse oximetry? Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen …

Nettet18. okt. 2024 · SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The human body needs a certain level of oxygen in the blood or it will not work as efficiently. Very low levels of SpO2 can cause very serious symptoms. fun games with kids at home
