Influence of different noninvasive oxygenation support devices on tidal volume.

ABSTRACT:

Background

Multiple devices are available for noninvasive oxygenation support, including non-rebreather oxygen mask (O₂-mask), high-flow oxygen through nasal cannula (HFNC), continuous positive airway pressure (CPAP), mask noninvasive ventilation (Mask-NIV) and helmet NIV (Helmet-NIV). As tidal volume is a key determinant of efficacy and safety during ventilatory support, we assessed whether it was influenced by the type of noninvasive oxygenation device.

Methods

A bench study using a manikin with a realistic face connected to a lung simulator was performed. Six conditions were assessed: no device, O₂-mask, HFNC, CPAP, Mask-NIV and Helmet-NIV. Three respiratory mechanics were simulated (normal, obstructive, restrictive), at three simulated efforts (low,
