Not be as effectively countered by simply increasing rate of respiration. and the effect of anatomic dead-space would Deeper breaths allow the dead space to account for a The greatest contribution to this increase occurs naturally (reflexly) throughĭepth of respiration. Ventilation is achieved through an increase in rate and depth of respiration, Respiratory volume as high as 150 liters per minute while this huge increase in Their cardiac output as high as 30 liters per minute, and their minute Pulmonary ventilation rate) and cardiac output are approximately equal. May have noticed that, at rest, the minute respiratory volume (sometimes called Ventilation:Perfusion Equality: Only when ventilation and perfusion areīoth functional, and functionally coordinated (optimized) can gas exchange between the blood and the alveolar air be efficient (more on this below). Perfusion of the Lungs: the transfer of blood to and from the lung Ventilation of the Lungs: the drawing of air in and out of the conducting pathways from the nose or mouth to the alveoli Pulmonary Ventilation and Perfusion: the Respiratory Zone
