WebApr 3, 2024 · How Does a Pulse Oximeter Work? A pulse oximeter is a small device that is commonly placed on a person’s fingertip or earlobe. It works by emitting light at two different wavelengths, typically red and infrared, which pass through the body part and are absorbed by pulsatile arterial blood. WebIf a finger pulse oximeter is being used, then a sensor probe is clipped onto one’s index finger, over the fingernail. A pulse oximeter consists of a pair of light-emitting diodes. One of the diodes transmits a beam of light with red wavelengths, while the other transmits light with infrared wavelengths.

WebApr 3, 2024 · Oxiline Pulse X Pro. Provides readings for Oxygen saturation (SpO2), perfusion index (PI) and heartbeats per minute (BPM) VTEC™ AX sensor to provide unparalleled accuracy for reliable results ... WebPulse oximeter sensors work by use of a light-emitting diode and receptor to measure blood oxygen saturation. Oxygen saturation is the percentage of oxygen attached to the hemoglobin in the blood. The determining principle works based on the fact that oxygenated blood takes in more infrared light while deoxygenated blood takes in more red light. fisher 525
