Hi doctor, what is correct way of measuring sp02 for any copd patient. I am seeing different reading on oximeter. Sometime it shows 95-96, then after 1 min of gap, if I measure then it shows 98 again. If I wake up and measure then it falls 95-97 and if I sit properly then it comes 98-99. I am confused what is correct way to measure sp02. I tried 6 min walk and measure. Reading shows 95.96.97.98 within 10 sec. Is this correct?
