The occluded airway pressure generated by contraction of inspiratory muscles was measured in spontaneously breathing, anesthetized, vagotomized cats at thoracic volumes below, at, and above true FRC (range, -8 to +28 ml/kg). A relatively constant neural drive at all volumes was shown by recordings of integrated phrenic nerve and external intercostal muscle activities. Peak occlusion pressure declined progressively with increasing thoracic volume and increased with occlusion volumes below FRC… CONTINUE READING
