Background: During the COVID-19 pandemic, the need for noninvasive respiratory support devices has dramatically increased, sometimes exceeding hospital capacity. The full-face Decathlon snorkeling mask, EasyBreath® (EB® mask), has been adapted to deliver continuous positive airway pressure (CPAP) as an emergency respiratory interface. We aimed to assess the performance of this modified EB® mask. Methods: CPAP set at 5, 10, and 15 cmH2O was delivered to 10 healthy volunteers with a high-flow system generator set at 40, 80, and 120 L min-1 and with a turbine-driven ventilator during both spontaneous and loaded (resistor) breathing. Inspiratory CO2 partial pressure (PiCO2), pressure inside the mask, breathing pattern and electrical activity of the diaphragm (EAdi) were measured at all combinations of CPAP/flows delivered, with and without the resistor. Results: Using the high-flow generator set at 40 L min-1, the PiCO2 significantly increased and the system was unable to maintain the target CPAP of 10 and 15 cmH2O and a stable pressure within the respiratory cycle; conversely, the turbine-driven ventilator did. EAdi significantly increased with flow rates of 40 and 80 L min-1 but not at 120 L min-1 and with the turbine-driven ventilator. Conclusions: EB® mask can be safely used to deliver CPAP only under strict constraints, using either a high-flow generator at a flow rate greater than 80 L min-1, or a high-performance turbine-driven ventilator.

During the COVID-19 pandemic, the need for noninvasive respiratory support devices has dramatically increased, sometimes exceeding hospital capacity. The full-face Decathlon snorkeling mask, EasyBreath (EB mask), has been adapted to deliver continuous positive airway pressure (CPAP) as an emergency respiratory interface. We aimed to assess the performance of this modified EB mask and to test its use during different gas mixture supplies. CPAP set at 5, 10, and 15 cmH2O was delivered to 10 healthy volunteers with a high-flow system generator set at 40, 80, and 120 L min−1 and with a turbine-driven ventilator during both spontaneous and loaded (resistor) breathing.

“…The maximal change between inspiratory and expiratory airway pressure was measured, and expressed as peak-to-peak airway pressure (P-P) [12]. For each CPAP device, the relative change in WOB was calculated and expressed as a percentage of the WOB measured with the ICU ventilator.…”

Background Several forms of noninvasive ventilatory supports have a high consumption of oxygen which may precipitate oxygen shortage, as experienced during the COVID-19 pandemic. In this bench-to-bedside study, we assessed the performances of a new continuous positive airway pressure (CPAP) device using a large a reservoir (the “Bag-CPAP”) designed to minimize oxygen consumption and compared it with other CPAP devices. Methods First, a bench study compared the performances of the Bag-CPAP and four CPAP devices to an intensive care unit ventilator. Two FiO2 targets (40-60% and 80-100%) at a predefined positive end expiratory pressure (PEEP) level between 5 and 10 cm H2O were tested and fraction of inspired oxygen (FiO2) and oxygen consumption were measured. Device-imposed work of breathing (WOB) was also evaluated. Second, an observational clinical study evaluated the new CPAP in 20 adult patients with acute respiratory failure in two hospitals in France. Actual FiO2, PEEP, peripheral oxygen saturation, respiratory rate and dyspnea score were assessed. Results All six systems tested in the bench study reached the minimal FiO2 target of 40% and four were able to reach at least 80% FiO2 while maintaining PEEP in the predefined range. The ratio of FiO2 delivered to the oxygen consumed was the highest with the new reservoir-based CPAP whatever the FiO2 target. The WOB induced by the device was slightly higher with the Bag-CPAP. In the clinical study, the Bag-CPAP was well tolerated and could reach high (>90%) and moderate (>50%) FiO2 with an oxygen flow rate of 15 [15-16] and 8 [7-9] L/min, respectively. Dyspnea score improved significantly after introduction of Bag-CPAP, and SpO2 increased. Conclusions In vitro, the Bag-CPAP exhibited the highest oxygen saving properties. It was well accepted clinically and reduces dyspnea. The Bag-CPAP may be useful to treat patients with acute respiratory failure in the field, especially when facing constraints in oxygen delivery.

Performances of CPAP Devices With an Oronasal Mask

Abstract: We found a significant variation in the performances of the 8 CPAP devices examined in this study. The technical characteristics and limitations of different CPAP devices should be considered when using in patients with hypoxemic acute respiratory failure.
