WebThe heat loss from warming inspired air has already been considered but not the heat loss for its humidification. By the time gases reach the trachea, their humidity is about 34 mg water vapour per litre of gas, this water coming from vaporization from the mucosa of the respiratory tract. WebDuring exhalation, the expired gas transfers heat back to the cooler tracheal and nasal mucosa by convection. As the saturated gas cools, it holds less water vapor. Condensation occurs on the mucosal surfaces during exhalation, and water is reabsorbed by the mucus … To ensure that the water vapor content of inspired gases is sufficient to meet the … prince charles letters to government https://bassfamilyfarms.com
