Face Mask Leak Determines Aerosol Delivery in Noninvasive Ventilation

Noninvasive face mask ventilation in patients with acute respiratory failure.

Noninvasive face mask ventilation has been used successfully in patients with paralytic respiratory failure. This study evaluated whether noninvasive face mask ventilation can be used for patients with acute respiratory failure due to intrinsic lung disease. Six patients with hypercapnia and four with hypoxemic acute respiratory failure met clinical and objective criteria for mechanical ventila...

Noninvasive Nasal Mask Ventilation

Setting: A ward of respiratory medicine of a tertiaryreferral teaching hospital. Patients: The study group included 15 patients with acute respiratory acidosis. These patients had pH less than 7.35 and PaC02 more than 60mm Hg, respiratory rate of 30 breaths or less per minute, hemodynamic stability, and alertness and willingness of cooperation with the NMV treatment. The control group consisted...

[Leak monitoring in noninvasive ventilation].

Nasal mask ventilation has been shown to be effective, but outcomes do not always match expectations because of mouth leaks, patient-ventilator asynchrony, or decreased upper airway patency. These developments are detected when they lead ultimately to circuit leaks that lower the effectiveness of ventilation through pressure loss, poor inspiratory triggering, and prolonged inspiratory time. The...

Noninvasive ventilation is more than mask ventilation.

Comparison of Aerosol Delivery by Face Mask and Tracheostomy Collar.

BACKGROUND The purpose of this study was to compare the performance of a tracheostomy collar, Wright mask, and aerosol mask attached to a jet nebulizer in facilitating aerosolized medication delivery to the lungs. We also compared albuterol delivery with open versus closed fenestration and determined the effect of inspiratory-expiratory ratio (I:E) on aerosol delivery. METHODS Albuterol (2.5 ...
