    Objective: To systematize evidence on the effectiveness of heat and moisture exchangers versus heated humidifiers for preventing ventilator-associated pneumonia in critically ill patients. Materials and Methods: A systematic, observational, and retrospective review with a quantitative approach, using the GRADE evaluation system to assess evidence quality. The studies were retrieved from PubMed, Scielo, Epistemonikos, and Sciencedirect. Results: Of the 10 articles reviewed, 30% (n=3) were meta-analyses, 20% (n=2) were systematic reviews, 40% (n=4) were randomized controlled trials, and 10% (n=1) were cohort studies. The studies came from Brazil (40%), Australia (20%), Turkey (20%), China (10%), and Italy (10%). The findings showed that 50% (n=5) of the articles indicated heat and moisture exchangers were more effective than heated humidifiers for preventing ventilator-associated pneumonia in critically ill patients. 30% (n=3) indicated no significant difference, and 20% (n=2) suggested no difference between the two methods. Conclusion: Heat and moisture exchangers are more effective than heated humidifiers for preventing ventilator-associated pneumonia in critically ill patients.
