Abstract

The perfusion ventilation imbalance isolated V Q mismatch or in association with the intrapulmonary shunt V Q ratio is the fundamental mechanism that determines the gasometric alterations present in the pathologies of the pulmonary parenchyma the airways and the pulmonary circulation As the ventilation imbalance can be corrected with oxygen administration the intrapulmonary shunt is refractory to oxygen therapy therefore it is considered a remarkable tool to evaluate the magnitude of pulmonary compromise especially when the patients are receiving mechanical ventilation with positive airway pressure
电阻抗层析成像:一种估计V/Q关系的新策略
灌注通气不平衡孤立的V Q不匹配或与肺内分流器相关的V Q比是决定肺实质、气道和肺循环病理中存在的气体测量改变的基本机制。由于通气不平衡可以通过给氧来纠正,肺内分流器对氧治疗是难治的,因此它被认为是评估肺损伤程度的重要工具特别是当患者接受气道正压机械通气时
