Excessive warming and humidification will cause:

Excessive warming and humidification will cause:

• A. Inaccurate CPAP pressures
• B. Water to pool in the CPAP tubing
• C. Increase in the intentional leak
• D. Decrease in unintentional leak

Answer: (B)

Excessive warming and humidification causes water vapor to condense as the warm, moist air travels through cooler CPAP tubing. When the air cools, it reaches its dew point and droplets form, pooling inside the tubing—often called rainout. This condensation can lead to water collecting in the tube, which may cause disturbance in delivery (noise, flow interruptions) and discomfort. The set pressure and the planned leak paths are not directly altered by humidity levels, so the main observable effect of too much humidity is the pooling water in the tubing.
