摘要

Have you ever been in need of a second opinion when your sanity is at stake? The pulse oximeter may be able to provide that second opinion if your brain is oxygen-deprived. This condition could affect you if you are a pilot, hiking in the high altitude of a mountain range, or even undergoing surgery. The pulse oximeter is a noninvasive instrument that monitors SpO_2 (saturation ofhemoglobin with oxygen) in your blood.
