How to Clean a Finger Pulse Oximeter

Finger pulse oximeter uses light-emitting diodes (LED) to emit red light and infrared light whose wavelengths are 660nm and 940nm respectively. By calculating the difference of the absorption of the lights in these two wavelengths between oxyhaemoglobin and deoxyhaemoglobin, oxygen saturation of blood can be obtained through a certain algorithm by means of built-in integrated circuits (IC). Hence, it is important to keep the probe clean so that the lights are not blocked by dirt or dusts.

Oil and/or dirt may accumulate over months no matter that the oximeter is used or not. It happens even for a new oximeter, although rarely. If your oximeter is not working accurately or shows error information, you may need to consider a cleaning. You need to use a soft dry clean cloth to clean the inside of the clip, especially near the LED (the light emitters, you can see a beam of red light from one, but no visible light comes from the other). Please note NEVER use water or other liquid to clean the probe because of the concern of corrosion or accumulation of mud.

In this way, you can keep your oximeter long life and have accurate readings. If you unfortunately have your oximeter damaged or dysfunctional, please check out our website http://www.clinicalguard.com to choose a reliable oximeter.
