heat and moisture exchanger

heat and moisture exchanger

a device placed within the patient's breathing circuit and the endotracheal tube, used to preserve moisture and heat. Fresh gas flow can evaporate moisture from mucous membranes in the respiratory tract.

heat and moisture exchanger

A device that retains some warmth and moisture from expired air and returns it to the intubated or laryngectomized patient during the following inspiration. The device prevents the patient from inhaling excessively cool, dry air that may damage the lower airways.

Since Cr = 1 is the optimal capacity ratio for sensible exchangers coupled in a run-around system, this may indicate that the optimal capacity ratio for a run-around heat and moisture exchanger system composed of two heat and moisture exchangers (see section "Run-Around Exchange with Heat Transfer and Moisture Transfer") is Cr = 0.
