The Foam Nose-A New Disposable Heat and Moisture Exchanger: A Comparison With Other Similar Devices

Abstract

The Foam Nose (Kemi-Intressen AB), a heat- and moisture exchanger (HME), was compared with two other commercially available HME's with respect to its heat and moisture exchanging capacity. During steady state, 77% of the expired humidity is restored to the airways with the Foam Nose, 63% with HME Portex and 63% with HME Dameca.
