The OxyMask™ development and performance in healthy volunteers

BACKGROUND: The OxyMask(™) is a unique, open-style, oxygen mask that was originally developed in 2005. The original mask was modified, using computational fluid dynamics numerical simulations, with the goal of allowing it to produce a wider range of FiO(2). This analysis was used to guide the modification of the mask shell and the location for the oxygen diffuser. METHODS: The new OxyMask was attached to 10 healthy subjects and used to deliver …
