Nasal ventilation

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...

Long-term nasal ventilation.

Impact of airflow communication between nasal cavities on nasal ventilation.

OBJECTIVE To investigate the impact of airflow communication between bilateral nostril sides on nasal ventilation. In addition, we try to validate the efficacy of the Draf III procedure from the aerodynamics perspective. METHODS One health model and two disease models were constructed. These included 2 patients with nasal septum perforation and 1 patient who received the Draf III procedure. W...

Determinants of effective ventilation during nasal intermittent positive pressure ventilation.

Our aim was to verify in healthy subjects submitted to nasal intermittent positive pressure ventilation (nIPPV) with a volumetric ventilator on controlled mode, whether changes in ventilator settings (delivered tidal volume (VT), respiratory frequency (fR) and inspiratory flow (V'I) could influence effective minute ventilation (V'E), thus allowing identification of the settings resulting in the...
