Heliox	Heliox mechanical ventilation	-

Primary Outcome Measures

Name	Time	Method
Changes in acid-base balance and oxygenation	Parameters recorded first at the baseline during ventilation with air-oxygen gas mixture, then after 15 and 60 minutes of the heliox ventilation and finally 15 and 60 minutes after switching back to air-oxygen ventilation.	Acid-base balance and oxygenation assessed on arterial blood gas samples, saturation measured with a pulse oximeter and calculated values of oxygenation index and alveolar-arterial oxygen tension difference.

Secondary Outcome Measures

Name	Time	Method
Changes in respiratory parameters	Parameters recorded first at baseline during ventilation with air-oxygen gas mixture, then after 15 and 60 minutes of the heliox ventilation and finally 15 and 60 minutes after switching back to air-oxygen ventilation.	Analyzed parameters: tidal volume (VT, \[ml/kg\]), minute ventilation (VE, \[l\]) and peak expiratory flow rate (PEFR, \[l/min\]). Recorded ventilator settings: respiratory rate (RR), mean airway pressure (MAP) and fraction of inspired oxygen (FiO2).
