To assess non-invasive ventilation knowledge and skills among nurses and physicians in different contexts: equipment and contextual influences. Cross-sectional, descriptive study in 4 intensive care units (ICU) (1 surgical, 3 medical-surgical), 1 postsurgical recovery unit, 2 emergency departments (ED) and 3 wards, in 4 hospitals (3 university, 1 community) with 407 professionals. A 13-item survey, validated in the setting, was applied (Kappa index, 0.97 (95% CI [.965-.975]). Nurses (63.7% response); physicians (39% response). The overall percentage of correct responses was 50%. Scored from 1 to 5, with lower scores reflecting more knowledge, nurses scored 3.27±.5 vs 2.62±.5 physicians, respectively (mean difference,.65 (95% CI: .48-.82, P<.001). There were no differences between hospitals or units (P=.07 and P=.09). A notable percentage of respondents incorrectly identified the patient-ventilator synchronization strategy as "covering the expiratory port" (intentional leaks) and pressing the mask against the patient's face (unintentional leaks) (28.2% ICU, 22.5% ED, 8.3% postoperative resuscitation, 61.5% wards), with no difference between nurses and physicians (27.9% vs 23.4%, P=.6). Only 50% of nurse respondents correctly answered a question about measuring mask size and just 11.7% of the nurses knew the "2-finger fit" adjustment. There was no difference in nurses' and physicians' knowledge according to the setting studied. The lack of knowledge regarding NIV therapy depended on training received and material available. To reduce the existent confusion between intentional and nonintentional leak, the use of a single type of NIV supply and providing an appropriate level of training for nurses is recommended.
