Anyone who experiences numbness, tingling, or changes in skin color should promptly notify a doctor. The main risk of pulse oximetry is a false reading. The accuracy of pulse oximeters depends on a correct fit, and minor changes in their positioning can produce an inaccurate reading. A person who rolls over in their sleep may loosen the device, causing it to give a false alert. Oxygen saturation may also dip for brief periods due to other factors, such as a change in sleeping position or momentary breath-holding. A pulse oximeter gives an alert even when the drop is temporary and harmless. For people with health anxiety, or whose doctors have not helped them understand the role of a pulse oximeter, this can cause unnecessary worry.

However, having an oxygen saturation level lower than 95% for a short period cannot cause any damage to your body organs.
