Physiologic Markers of Disease Severity in ARDS

Joao F F M Ferraz et al. Respir Care. .

Abstract

Despite its significant limitations, the PaO2 /FIO2 remains the standard tool to classify disease severity in ARDS. Treatment decisions and research enrollment have depended on this parameter for over 50 years. In addition, several variables have been studied over the past few decades, incorporating other physiologic considerations such as ventilation efficiency, lung mechanics, and right-ventricular performance. This review describes the strengths and limitations of all relevant parameters, with the goal of helping us better understand disease severity and possible future treatment targets.

Keywords: ARDS; classification; mortality; prognosis; risk stratification.
