Heliox Improves Carbon Dioxide Removal during Lung Protective Mechanical Ventilation

Figure 1

Respiratory parameters during heliox ventilation for 3 hours ( to ) and after switch to normal oxygen in air mixture ( to ). Measurements started prior to heliox administration (). Data are means SEM. (a) Minute volume ventilation (L min⁻¹); (b) respiratory rate (breaths min⁻¹); (c) peak pressure (cm H₂O); (d) PaCO₂/end tidal CO₂ gradient (mmHg); (e) airway resistance (cm H₂O mL⁻¹ sec⁻¹); and (f) lung compliance (mL cm⁻¹ H₂O). : .
