While pulse oximetry is a valuable tool, it has some limitations:
- Motion Artifacts: Movement can cause inaccuracies in the readings. - Poor Perfusion: In cases of poor blood flow, the readings may not be reliable. - Skin Pigmentation and Thickness: These factors can sometimes affect the sensor’s accuracy. - Delayed Detection: Pulse oximetry may not detect sudden changes in oxygenation as quickly as other methods.
