Abstract/OtherAbstract:
The application of the Starling resistor concept of the lungs during continuous positive pressure ventilation (CPPV) was evaluated. Ventilation and hemodynamics were studied in eight anesthetized and paralyzed dogs before and during the use of CPPV. CPPV resulted in an increase in transpulmonary pressure and functional residual capacity (FRC), and a decrease in arterial pH and mixed venous oxygen tension (PvO2). Cardica index decreased 32% (p less than 0.01) and stroke volume 51% (p less than 0.01). Neither right nor left transmural pressures changed but pulmonary vascular resistance increased 189% (p less than 0.01). This study supports the concept that the pulmonary vasculature behaves as a Starling resistor during the use of CPPV. The increase in pulmonary vascular resistance must be considered when transpulmonary pressure is raised by CPPV.
