“…In subjects with acute respiratory failure, Ozsancak et al 125 found that the oronasal mask and total face mask were perceived to be equally comfort- able and had similar application times. In another study of subjects with acute respiratory failure, Chacur et al 126 reported that the total face mask was more comfortable than the oronasal mask and suggested that the total face mask should be available as an option in units where NIV is routinely applied.…”

“…The rate of NIV discontinuation was also very low in our study, especially compared with other investigations [7,9]. The aforementioned high expertise with the technique may explain this result, as great care was taken by the teams to prevent skin damage, eye irritation and facial erythema [9].…”

“…In real life, the oronasal mask is considered the first choice of interface [6] because it minimises the problem of air leaks and allows breathing through both nose and mouth. Randomised controlled trials (RCTs) [7,8] showed that oronasal and full-face masks are equally tolerated and effective in improving gas exchange, but early discontinuation because of intolerance may be quite high with both interfaces [7]. It has therefore been suggested that if NIV has to be prolonged beyond 24 h, it would appear reasonable to switch to different interfaces to improve patient comfort and avert skin lesions [9].…”

The choice of the interface for noninvasive ventilation (NIV) is a key factor in NIV success. We hypothesised that a new helmet specifically design to improve performance in hypercapnic patients would be clinically equivalent to a standard oronasal mask.In a multicentre, short-term, physiological, randomised trial in chronic obstructive pulmonary disease patients facing an acute hypercapnic respiratory failure episode, we compared the changes in arterial blood gases (ABGs) and tolerance score obtained using the helmet or mask, and, as secondary end-points, dyspnoea, vital signs, early NIV discontinuation and rate of intubation. 80 patients were randomly assigned to receive NIV either with the helmet (n=39) or mask (n=41), using an intensive care unit ventilator.Compared with baseline, in the first 6 h, NIV improved ABGs, dyspnoea and respiratory rate ( p<0.05) in both groups. Changes in ABGs and discomfort were similar with the two groups, while dyspnoea decreased more ( p<0.005) using the mask. The rate of intubation and the need for interface change during the whole period of NIV were very low and not different between groups.The new helmet may be a valid alternative to a mask in improving ABGs and achieving a good tolerance during an episode of acute hypercapnic respiratory failure. @ERSpublications In COPD patients undergoing NIV, an oronasal mask and a helmet equally improved ABGs and tolerance score

“…In vitro studies have found that use of a full-face mask can increase CO 2 rebreathing to a maximum of 3 mL during each breath [17]. Likewise, clinical research has reported that full-face masks and nasal-oral masks have similar influence on CO 2 rebreathing [18]. CO 2 rebreathing is also connected with factors such as the type and location of the exhalation valve, as well as with the inspiratory and expiratory pressure [19].…”

Background: Research on the effect of nebulizer location on aerosol delivery during noninvasive ventilation has reached inconsistent conclusions. Objective: To investigate the effects of nebulizer position on aerosol delivery efficiency and ventilator performance during noninvasive ventilation. Methods: The Active Servo Lung 5000 respiratory simulation system (ASL5000) was used to simulate a COPD patient. The noninvasive ventilator was set to the spontaneous breathing mode. Six nebulizer positions, 2 exhalation valve types (single-arch exhalation port and whisper swivel), 4 combinations of inspiratory and expiratory pressure, and 2 respiratory rates were used. Results: Significant differences between nebulizer positions existed in aerosol delivery (p < 0.05). Aerosol delivery efficiency was lower for nebulizer locations on either side of the exhalation valve and next to the ventilator outlet. When the nebulizer was located between the exhalation valve and the simulated lung, increased inspiratory pressure increased and increased expiratory pressure decreased delivery efficiency (both p < 0.05). When the nebulization device was located between the exhalation valve and the ventilator, no obvious trend was observed. Compared to baseline, nebulization lowered the air leakage volume displayed on the ventilator. There were no differences in ventilator performance between different nebulizer positions. Conclusions: The closer the nebulizer was to the exhalation valves or ventilator, the lower the aerosol delivery efficiency. Nebulizer position had little clinically significant effect on ventilator performance.
