AARC Evidence-Based Clinical Practice GuidelinesCare of the Ventilator Circuitand Its Relation to Ventilator-Associated PneumoniaSummary of Recommendations Ventilator circuits should not be changed routinely for infection control purposes. The maximumduration of time that circuits can be used safely is unknown. evidence is lacking related to ventilator-associated pneumonia (VAP) and issues of heated versusunheated circuits, type of heated humidifier, method for filling the humidifier, and technique forclearing condensate from the ventilator circuit. Although the available evidence suggests a lower VAP rate with passive humidification than withactive humidification, other issues related to the use of passive humidifiers (resistance, dead spacevolume, airway occlusion risk) preclude a recommendation for the general use of passive humidifiers.
