Non-invasive ventilation
NIV was provided by BiPAP-Vision™ ventilator (Philips Respironics Inc, Murrysville, PA, USA) set at the BIPAP mode and applied by a nasal mask, with room air, for 60 minutes. Volunteers were studied during the application of NIV (inspiratory pressure of 14cmH2O and expiratory pressure of 4cmH2O), with a pressure support of 10cmH2O and without oxygen support (FIO2 0.21). These pressure levels were chosen based on the current practice of NIV in the intensive care setting.
