When you are measuring your oxygen saturation level and pulse using a finger oximeter, it’s important to ensure the reading is correct. Certain conditions may cause the oximeter to give an inaccurate reading. A good way to double check the accuracy of a pulse oximeter reading is to check your pulse manually and compare the two readings.
Some common reasons for an inaccurate oximeter reading include the following:
Other factors that can affect the pulse oximeter readings include the following:
If your pulse oximeter reading is abnormally high or low, make sure you are following all recommended procedures for taking a pulse measurement and try checking your levels again.
The normal range for blood oxygen saturation is between 96% and 100%. If your oxygen saturation level is below 90%, seek medical help immediately, as these levels could quickly lead to life-threatening complications. Levels between 90% and 95% may signify a less severe hypoxia and require immediate action to prevent a more severe case of hypoxia.
