Abstract
Two types of devices are widely used to heat and humidify inspired gases during invasive mechanical ventilation. One type is active humidification, with the use of heated humidifiers and the other is passive humidification with the use of heat and moisture exchangers. This chapter will address the choice of device depending on the patients’ condition. Regarding heat and moisture exchangers, the frequency of replacement will be discussed, along with bedside adjustment. We show that contrary to manufacturers’ recommendations, these devices need not to be changed as often. Assessment of adequacy of inspired gas condition will also be addressed. Importantly, no study has ever demonstrated the superiority of one device compared to another in terms of important patient outcomes, whether it be mortality, duration of mechanical ventilation, length of ICU stay, or incidence of ventilator-associated pneumonia.
