Measuring the saturation pulsatile of oxygen (SPO2) is performed by which device?

Explanation:
Measuring pulsatile oxygen saturation is done with a pulse oximeter. This device clips onto a fingertip or earlobe and uses two light wavelengths to assess how much hemoglobin is carrying oxygen. As arterial blood pulses, the device detects changes in light absorption and calculates the oxygen saturation (SpO2) and pulse rate noninvasively. The stethoscope listens to sounds, the thermometer checks temperature, and the sphygmomanometer measures blood pressure, so they don’t provide SpO2 readings.
