The pressure effects of facemasks during noninvasive ventilation: a volunteer study

Summary Noninvasive ventilation by facemask is commonly used for patients with respiratory failure. We evaluated the pressure exerted by two types of facemask on the faces of 12 healthy volunteers while they were being given different levels of continuous or bi‐level positive airway pressure ventila...

Description
Summary:Summary Noninvasive ventilation by facemask is commonly used for patients with respiratory failure. We evaluated the pressure exerted by two types of facemask on the faces of 12 healthy volunteers while they were being given different levels of continuous or bi‐level positive airway pressure ventilation. The mean (SD) pressure recorded on the bridge of the nose was much higher than that on the cheek (nose: 65.8 (21.2) vs cheek 15.4 (7.2) mmHg, p
