Abstract
Gas exchange abnormalities is the pathophysiology characteristic of acute respiratory distress syndrome (ARDS). The severity of gas exchange abnormalities not only reflect the severity and outcome of the disease, but could also be an important index to guide individual mechanical ventilation settings and evaluate the therapeutic effects of inhaled vasodilator. The common techniques to measure gas exchange include multiple inert gas elimination technique, automatic lung parameter estimator, electrical impedance tomography, and single-photon emission CT. Nowadays, bedside techniques and measurements for improving gas exchange function in ARDS patients are still limited. Therefore, the improvement and promotion of bedside real-time gas exchange monitoring technology may achieve the goal of personalized medicine in ARDS. This article reviewed the common evaluation methods of gas exchange function in ARDS and their significance, in order to pay more attention to the evaluation of gas exchange function and further improve the prognosis of patients with ARDS.
