Figure 3From: Measurement of pressure-volume curves in patients on mechanical ventilation: methods and significanceRespiratory (left panel) and pulmonary (right panel)pressure-volume curves obtained by the supersyringe technique (clear circle), theinspiratory occlusion technique (clear square) and the constant flow technique at 3 (filled circle)and 9 (clear triangle) l/min flow. The curves obtained using the constant flow technique at9 l/min are slightly shifted to the right due to the generation of a resistivepressure. The curves obtained by the other methods are not significantlydifferent. From Lu et al [10].Back to article page
