Variations in systemic arterial pressure with positive-pressure breathing are frequently used to guide fluid management in hemodynamically unstable patients. However, because of the complex physiology that determines the response, there are important limitations to their use. Two papers in a previous volume add pulmonary hypertension as limitations. Uncritical use of ventilatory-induced changes in arterial pressure can lead to excessive volume therapy and potential clinical harm, and they must be used with respect and thought.
在血流动力学不稳定的患者中,常通过正压通气时的体循环动脉压变化来指导液体管理。然而,由于决定这种反应的复杂生理学,其应用存在重要限制。前一卷中的两篇论文增加了肺动脉高压作为限制因素。不恰当地使用通气引起的动脉压变化可能导致过度的容量治疗和潜在的临床危害,必须谨慎使用。
