How RELIABLE Is Pulse Oximetry?

Описание: Pulse oximetry is a non-invasive method used to measure the oxygen saturation level of the blood.

However, it's crucial to exercise caution when relying on pulse oximetry in cases of carbon monoxide (CO) poisoning. Carbon monoxide binds to hemoglobin with a much higher affinity than oxygen, which pulse oximeters can mistakenly interpret as oxygenated hemoglobin.

As a result, the device may display falsely elevated oxygen saturation levels, potentially delaying the diagnosis and treatment of CO poisoning.
