Table 1. Pulmonary Arterial and Capillary Pressures
Mean ± SD. Data from 18 isolated blood-perfused rabbit lungs; pulmonary arterial pressure at a flow rate of 100 ml/min and a pulmonary venous pressure of 4 cm H2O; capillary pressure determined by simultaneous occlusion of inflow and outflow of the pulmonary vasculature (double occlusion technique). Hydrochloric acid injury was induced following baseline determinations (time 0 min). Partial liquid ventilation was instituted 30 min after induction of hydrochloric acid injury (time 30 min). There were no significant changes over time within the groups or significant differences between the three groups at corresponding times. Thus, neither hydrochloric acid instillation nor subsequent perfluorocarbon instillation affected mean pulmonary arterial or capillary pressures.
