Why do I need a pulse oximetry test?

ANSWER

Pulse oximetry can:

  • Diagnose symptoms like shortness of breath
  • Track your blood oxygen level during surgery
  • Manage a heart or lung condition that could affect your blood oxygen levels, like heart failure, COPD, asthma, or pneumonia
  • Show if you need extra oxygen when you exercise
  • Show whether your breathing stops while you sleep, a condition called sleep apnea
