How to use a pulse oximeter? What do the values mean?

How to use a pulse oximeter? Finger pulse oximeters are used by many people especially after the COVID pandemic. I explain how to correctly use an oximeter to get good reliable readings and possible reasons why you may get errors or inaccurate measurements. The pulse oximeter only reports the peripheral pulse and oxygen saturation. I recommend keeping your hand relaxed or supported on a surface, putting the pulse oximeter on a warm finger to ensure there is good blood flow and to leave it on for at least a few seconds before noting the values reported. I also discuss about normal ranges for pulse and oxygen saturation. Do note that the pulse rate can go up quite a lot especially if you are exercising or doing anything strenuous. ☕ Please consider supporting my work by "buying a coffee" : https://www.buymeacoffee.com/scstanel ======= Disclaimers: ------------- For all viewers/listeners: The information presented here or in other videos and posts on this channel is not medical advice.
