High-velocity nasal insufflation with oxygen assist module versus conventional high-velocity nasal insufflation after extubation: an open-label randomized crossover study.

ABSTRACT:

Background

The current technology of high-velocity nasal insufflation (HVNI) can be equipped with an oxygen assist module (OAM) that continuously monitors and automatically adjusts the inspired oxygen fraction (FiO₂) to maintain oxygen saturation by pulse oximetry (SpO₂) within the target range. This study aimed to evaluate the use of HVNI with OAM compared to conventional HVNI in patients after endotracheal extubation.

Methods

This randomized crossover study enrolled 16 mechanically ventilated subjects who were ready to wean. The subjects were randomized to protocol A (HVNI with OAM for 60 min, followed by conventional HVNI for another 60 min) or protocol B (conventional HVNI for 60 min, followed by HVNI with OAM for another 60 min) after extubation.
