T/F A Heat and Moisture Exchanger (HME) primarily reduces heat loss by warming the inspired gas.

T/F A Heat and Moisture Exchanger (HME) warms inspired gases to a temperature of 35-37°C

T/F At this temperature a Heat and Moisture Exchanger (HME) achieves a humidity of 85-93%

T/F A Heat and Moisture Exchanger (HME) reduces the risk of bacterial and viral cross-infection between patients.

T/F A Heat and Moisture Exchanger (HME) is less effective when using high gas flows in a circle system.
