Heliox can lower respiratory resistance, improve the oxygenation, reduce respiratory distress and lung injury caused by mechanical ventilation.
Heliox can improve the oxygenation, reduce respiratory distress and lung injury caused by mechanical ventilation. Heliox has not been widely used. More studies on the effects and safety of Heliox in addition to NIPPV and mechanical ventilation should be tried.
