A pulse oximeter is a medical device that measures the oxygen saturation level (SpO2) and pulse rate of a person, typically using a non-invasive sensor clipped onto a fingertip or earlobe. Key technical specifications include the SpO2 measurement range, often between 70% and 100%, and pulse rate range, usually from 30 to 250 beats per minute. Accuracy for SpO2 is typically within ±2% to 3%, and for pulse rate, it is usually within ±3 beats per minute.
