Popis: | The perfusion of the diaphragm, the interchondral portion of the intercostals and the scaleni have been calculated from measurements of cardiac output and its fractional distribution in rabbits. At every level of ventilation the diaphragm is more perfused than the interchondral portion of intercostal muscles or scaleni. During quiet breathing the diaphragmatic blood flow is 39.5 ml · min −1 · 100 g −1 . During maximal CO 2 induced hyperventilation the blood flow reaches 81.4 ml · min −1 · 100 g −1 . During eleetrophrenic respiration the blood flow is higher than during hyperventilation. During hyperventilation the increase in blood flow is not significant in the extradiaphragmatic inspiratory muscles. |
