How would moisture or condensation buildup on the sensor membrane affect the measured FIO2?

Moisture or condensation buildup on the sensor membrane can interfere with the accurate measurement of the fractional inspired oxygen (FIO2) by creating a barrier between the sensor and the gas being analyzed. This can lead to false readings, as the presence of water vapor may cause the sensor to misinterpret the concentration of oxygen in the gas mixture. Additionally, condensation can affect the sensor's responsiveness and calibration, potentially resulting in delayed or inaccurate measurements. Overall, such interference can compromise the reliability of FIO2 monitoring in clinical settings.
