Practice Guideline
Humidification during invasive and noninvasive mechanical ventilation: 2012.
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 following the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scoring system: 1. ⋯ Passive humidification is not recommended for noninvasive mechanical ventilation. 6. When providing humidification to patients with low tidal volumes, such as when lung-protective ventilation strategies are used, HMEs are not recommended because they contribute additional dead space, which can increase the ventilation requirement and P(aCO(2)). 7. It is suggested that HMEs are not used as a prevention strategy for ventilator-associated pneumonia.

Endotracheal tubes (ETTs) impose a substantial respiratory work load on mechanically ventilated patients. Automatic tube compensation (ATC) should overcome this flow-dependent resistive work load; however, ETT resistance can be increased by tracheal secretions or ETT deformities. Our bench study investigated whether ATC provides effective respiratory work load relief in used ETTs. ⋯ ATC does not necessarily compensate for an ETT-imposed respiratory work load. ETT configuration changes and tracheal secretions can increase ETT resistance and decrease the ability of ATC to compensate for the increased respiratory work load.

Information and opinions were sought on the need for graduating and practicing respiratory therapists to obtain 66 competencies necessary for practice in 2015 and beyond, the required length of respiratory care programs, the educational needs of practicing therapists, current and future workforce positions, and the appropriate credential needed by graduating therapists. ⋯ There was good agreement that graduate and practicing therapists should obtain the vast majority of the 66 competencies surveyed and that the entry level credential should be the RRT. Similar numbers of managers favored an entry level baccalaureate degree as favored an associate degree.
