Application of heat and humidification to inspired gases during mechanical ventilation has been shown to prevent such complications as hypothermia, drying of airway secretions, and destruction of airway epithelium. Warming and humidification are accomplished through the use of heated humidifiers or, more commonly, in-line heat and moisture exchangers. The preference of either device varies depending on such factors as the type of patient, amount of airway secretions, anticipated length of ventilation, or choice by respiratory therapists. The choice of either device may have varying effects on underlying respiratory mechanics in the ventilated patient. This article primarily explores the available data on the effect of airway humidification devices on tidal volume and other airway mechanics in the ventilated patient.
