Pulmonary Pressure Gradients and Hemodynamics

Conference paper
Part of the Anaesthesiologie und Intensivmedizin/Anaesthesiology and Intensive Care Medicine book series (A+I, volume 187)


Because the hilus of the lung does not anchor it very securely, the lung is largely supported by the pleural surfaces and ist therefore subjected to the combined forces of subatmospheric (negative) pleural pressures and the effects of gravity on the lung structure itself. As a result of these combined forces, intrapleural pressure is lower [15] and pulmonary alveoli are larger in size at the apex than at the base of the upright lung [20]. The lower regions of the lung are thus relatively compressed, while the upper parts are relatively overexpanded [37].
