Cardiorespiratory interactions - Film n° 14

Same recording as the previous film, in the same patient, but at a faster projection speed. This visualizes at heartbeat 3 (end-inspiratory) a lengthening of the acceleration time of the pulmonary artery flow. Coupled with the drop in maximum velocity of the flow, it causes a decrease in the mean acceleration of the right ventricle at heartbeat 3, reflecting the increase in its afterload
