Have been experiencing a number of worrying symptoms my GPS have been dismissing. Shortness of breath, extreme faitugue and weakness, chest tightness, worsening, mental confusion and a persistent cough.
Bought a pulse oximetry reader but not sure how to read the measurements properly. Checked on this forum and what I read there, about low oxygen levels, has alarmed me.
Just taken my oxygen level, and the reading is 98/80. What I read here was that oxygen levels should be over 92. As the first sum is 98 that seems okay, then? But not sure what the second reading indicates as it IS below 92? Is there cause to be alarmed? Possible heart failure?
