Sep 15 2014· Oronasal masks are often used in acute respiratory failure while nasal masks are preferred in patients with chronic respiratory failure. 1 However the use of nasal masks can result in mouth leaks with implications on sleep quality. 2 To reduce these leaks oronasal masks have been applied during home noninvasive ventilation (NIV). 3 Until now

Jul 27 2012· Brief Summary: Recently the investigators demonstrated that nasal route ventilation is superior to the nasal-oral combined ventilation in the absence of jaw thrust and chin up maneuvers. The investigators hypothesize nasal mask ventilation may reduce the incidence of difficult mask ventilation during the induction of general anesthesia by: 1) …

Jul 22 2021· Noninvasive ventilation provided oxygenation and ventilation during preoxygenation and from induction up to laryngoscopy but neither oxygenation nor ventilation during laryngoscopy. In the high-flow nasal oxygen group preoxygenation was delivered by continuous oxygen via binasal prongs with an oxygen flow of 60 L/min through a heated

Mar 01 2003· The oral and nasal contributions to inhaled ventilation were simultaneously quantified during sleep in 10 healthy subjects (5 men 5 women) aged 43 ± 5 yr with normal nasal resistance (mean 2.0 ± 0.3 cmH 2 O · l −1 · s −1) by use of a divided oral and nasal mask.Minute ventilation awake (5.9 ± 0.3 l/min) was higher than that during sleep (5.2 ± 0.3 …

Jun 01 2008· Nasal mask ventilation was more effective than combined oral-nasal mask ventilation in apneic nonparalyzed adult subjects during induction of general anesthesia. The authors suggest that nasal mask ventilation rather than full facemask ventilation be considered during induction of anesthesia.

This study was undertaken to determine the efficacy of nasal mask (NM) versus full face mask (FFM) for the delivery of noninvasive ventilation (NIV) in subjects with nocturnal hypoventilation. A total of 16 patients (11 males) were enrolled all with nocturnal hypoventilation currently treated at home with NIV via pressure preset devices.

Mechanism for providing a patent airway during nasal mask ventilation. ( A ) During nasal mask ventilation positive pressure is generated only in the nasopharynx; the pressure gradient between the nasopharyngeal and oropharyngeal cavities is able to overcome the effect of gravity on the soft palate and the tongue pushing forward and opening the upper airway.

If ventilation is helpful and effective there is no need for oral airway one of whose characteristics is opening the nasal route by displacing the tongue. Is using nasal mask better than nasal route during face or combined mask ventilation? That is still the question.
