Fingertip Pulse Oximeter

Pulse oximeter is a device that measures the oxygen level in the blood. It is a non-invasive and painless test. It uses light beams to determine the percentage of oxygen in red blood cells. Normal range: A normal reading is usually between 95% and 100%. Low oxygen levels: Readings below 92% may require medical attention. Factors affecting accuracy: Poor circulation, skin pigmentation, and nail polish can affect readings. Heart rate measurement: It also measures heart rate, with a normal range between 50 and 90 bpm.
