Figure 2From: Heliox improves pulmonary mechanics in a pediatric porcine model of induced severe bronchospasm and independent lung mechanical ventilationPercentage improvement of resistance, tidal volume and complianceafter lungs were crossed over from a nitrogen-oxygen gas mixture (nitrox) to ahelium-oxygen gas mixture (heliox) and from heliox to nitrox. A negativepercentage improvement indicates a deterioration of lung function, i.e. anincrease in resistance is depicted as a negative percentage improvement.Back to article page
