【正文】 Pulmonary ventilation volume and alveolar ventilation volume ? Minute ventilation volume *12~*18 6~9 L/min , maxmum 70~150 L/min ? Dead space and alvoelar ventilation anatomical dead space physiological dead space alveolar ventilation Gas Exchanges The principle of gas exchages ? Factors affecting diffusion rate partial presure difference △ P solubility of gas S area available for dissusion A temperrature T distance to diffuse(thickness of the diffusion barrier) d molecular weight of gas MW △ P5 Respiration Chemical reduction of molecular oxygen to form water is the primary source of energy for animals. The principal site for the reaction occurs within the mitochondria. Without this reaction life cannot exist for more than seconds. Coincidental with the reduction of O2 is the production of CO2。 早產(chǎn)嬰兒 Inspira tor y Reser ve V olume 補(bǔ)吸氣量 1. 5 2. 0 L T idal V olume 潮氣量 M, F 0. 5 L Inspira tor y Capa cit y 深吸氣量 V it al Capa cit y M 3. 5 L F 2. 5 L Expi ra tor y Reser ve V olume 補(bǔ)呼氣量 0. 9 1. 2 L T ot al Lung Capa cit y 肺總?cè)萘?
