AARC Clinical Practice Guideline Humidification During Invasive and Noninvasive Mechanical Ventilation: 2012 Ruben D Restrepo MD RRT FAARC and Brian K Walsh RRT-NPS FAARC We searched the MEDLINE, CINAHL, and Cochrane Library databases for articles published between January 1990 and December 2011. The update of this clinical practice guideline is based on 184 clinical trials and systematic reviews, and 10 articles investigating humidification during invasive and noninvasive mechanical ventilation. The following recommendations are made follow- ing the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scoring system: 1. Humidification is recommended on every patient receiving invasive mechanical ventila- tion. 2. Active humidification is suggested for noninvasive mechanical ventilation, as it may improve adherence and comfort. 3. When providing active humidification to patients who are invasively ventilated, it is suggested that the device provide a humidity level between 33 mg H O/L and 2 44 mg H O/L and gas temperature between 34°C and 41°C at the circuit Y-piece, with a relative 2 humidity of 100%. 4. When providing passive humidification to patients undergoing invasive mechanical ventilation, it is suggested that the HME provide a minimum of 30 mg H O/L. 5. Passive 2 humidification is not recommended for noninvasive mechanical ventilation. 6. When providing humidification to patients with low tidal vo
