A disposable condenser humidifier for use during anaesthesia

Abstract

A disposable heat and moisture exchanger ("Artificial Nose") which is designed for use during endotracheal anaesthesia is described together with an evaluation of its performance. It has a low dead space, minimal resistance to gas flow, and is potentially capable of conserving 50 per cent of the respiratory water loss in the intubated patient. © 1976 Canadian Anesthesiologists.
