Excerpt
Heliox has been reported to reduce work of breathing and to improve aerosol deposition in patients with acutely obstructed airways. We wanted to evaluate the effects of an aerosol delivery system (Aerogen, Inc, Mountain View, CA, USA) with a prototype heliox delivery system (Datex-Ohmeda, Inc, Madison, WI, USA) incorporating an electronic demand valve with an active exhalation valve, and its impact on aerosol deposition and tidal volume (Vt). …
