Clinical Trial: Heliox in Experimental Upper Airway Obstruction

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional




Official Title: PoC Study of Heliox With Helium-Fractions Between 25 and 75% in Experimental Upper Airway Obstruction

Brief Summary: Currently it is common medical wisdom that HELIOX (mixture of Helium in Oxygen) with a fraction of Helium below 60% is not effective in reducing airway obstruction. The investigators test the hypothesis that HELIOX with a fraction of Helium below 60% is still effective in relieving airway obstruction in a double-blind, randomized and controlled clinical PoC study with experimental upper airway obstruction.
