Figure 3From: Maintained inspiratory activity during proportional assist ventilation in surfactant-depleted cats early after surfactant instillation: phrenic nerve and pulmonary stretch receptor activityRecordings of P aw , V T , P eso , and PSR f imp during CPAP and PAV after lung lavage. Note the shorter time to peak PSR f imp and the higher peak PSR f imp during PAV than during CPAP, giving a shorter inspiratory time.Back to article page
