Myself 33 years had covid test negative after cold and cough, but my oxygen saturation level have decreased from 99 to 94 and 94. no history of diabetes, hypertension and any breathing issue. why my oxygen saturation level is decreased in cold?
A doctor has provided 1 answer
Oximetry: The pulse oximetry reading can be adversely affected by vasoconstriction at the finger tip caused by cold environment. . I doubt that you have significant desaturation in any event at 94%.
