“…A criticism of this study is that it was conducted in healthy volunteers and thus the implications for long-term ventilation are unclear. 143 Willson et al 144 studied the effectiveness of a nasal mask versus an oronasal mask in patients with nocturnal hypoventilation. They reported that the type of interface did not affect gas exchange, and arousal indices were comparable for both masks.…”

For many patients with chronic respiratory failure requiring ventilator support, noninvasive ventilation (NIV) is preferable to invasive support by tracheostomy. Currently available evidence does not support the use of nocturnal NIV in unselected patients with stable COPD. Several European studies have reported benefit for high intensity NIV, in which setting of inspiratory pressure and respiratory rate are selected to achieve normocapnia. There have also been studies reporting benefit for the use of NIV as an adjunct to exercise training. NIV may be useful as an adjunct to airway clearance techniques in patients with cystic fibrosis. Accumulating evidence supports the use of NIV in patients with obesity hypoventilation syndrome. There is considerable observational evidence supporting the use of NIV in patients with chronic respiratory failure related to neuromuscular disease, and one randomized controlled trial reported that the use of NIV was life-prolonging in patients with amyotrophic lateral sclerosis. A variety of interfaces can be used to provide NIV in patients with stable chronic respiratory failure. The mouthpiece is an interface that is unique in this patient population, and has been used with success in patients with neuromuscular disease. Bi-level pressure ventilators are commonly used for NIV, although there are now a new generation of intermediate ventilators that are portable, have a long battery life, and can be used for NIV and invasive applications. Pressure support ventilation, pressure controlled ventilation, and volume controlled ventilation have been used successfully for chronic applications of NIV. New modes have recently become available, but their benefits await evidence to support their widespread use. The success of NIV in a given patient population depends on selection of an appropriate patient, selection of an appropriate interface, selection of an appropriate ventilator and ventilator settings, the skills of the clinician, the motivation of the patient, and the support of the family.

“…[11][12][13] Historically, masks that cover the mouth, nose, or both have been used to treat ARF, 9,14 until masks that cover larger surfaces of the face were available, with similar efficiency and more comfort. 15,16 These larger-volume total face masks reduce the respiratory rate, 17 use of accessory muscles, and P CO 2 14,17 when compared with oronasal masks, without clear superiority in terms of clinical outcomes. 14,[17][18][19] However, clinical studies 14,[16][17][18][19] that compared NIV masks used different methods and outcomes, baring unmeasurable subjective factors related to patients and staff.…”

BACKGROUND: Noninvasive ventilation (NIV) reduces intubation and mortality in patients with COPD exacerbation who present with respiratory failure, and the type of mask may affect its success. Our objective was to compare the performance of 3 different NIV masks in a lung model. METHODS: We set the lung simulator mechanics and respiratory rate, and tested a small oronasal mask, a total face mask, and a large oronasal mask. We added CO 2 at a constant rate into the system and monitored the end-tidal carbon dioxide. We used a mechanical ventilator to deliver NIV in 8 different combinations of inspiratory effort, pressure support, and expiratory positive airway pressure. We measured end-tidal carbon dioxide mask leakage, tidal volume, trigger time, time to achieve 90% of the inspiratory target during inspiration, and excess inspiratory time. RESULTS: We presented the mean ؎ SD of the 8 simulated conditions for each mask. The mean ؎ SD leakage was higher for the total face mask (51 ؎ 6 L/min) than for the small oronasal mask (37 ؎ 5 L/min) and for the large oronasal mask (21 ؎ 3 L/min), P < .001; but end-tidal carbon dioxide and tidal volume were similar. The mean ؎ SD 90% of the inspiratory target during inspiration was faster for the small oronasal mask (585 ؎ 49 ms) compared with the large oronasal (647 ؎ 107 ms) and total face mask (851 ؎ 105 ms), P < .001, all other variables were similar. CONCLUSIONS: In this model, we found that the type of mask had no impact on CO 2 washout or on most synchrony variables.
