The new Global definition of ARDS recently introduced a subgroup known as non-intubated ARDS. This study aimed to assess the risk of progression from noninvasive oxygen support to intubation and ARDS severity based on the SpO2 /FIO2 among non-intubated subjects with ARDS. ⋯ The non-intubated ARDS criteria encompassed a broader spectrum of subjects with lower in-hospital mortality compared to the Berlin criteria. The SpO2 /FIO2 and ARDS severity cutoff proposed in the new Global ARDS definition were valuable predictors of in-hospital mortality in these subjects.

The arterial to end-tidal carbon dioxide gradient (P [a-Et] CO2) reveals the ventilation-perfusion (V/Q) status of critically ill patients. V/Q mismatch has several causes and affects the clinical outcomes of critically ill patients. We investigated the relationship between P (a-Et) CO2 and the clinical outcomes in critically ill patients. ⋯ P (a-Et) CO2 is a simple, easily accessible indicator that potentially impacts patient care and outcomes as an independent marker for assessing disease severity and predicting mortality, especially in non-respiratory critical care scenarios.

An Intensive Care Medicine (ICM) rotation provides fantastic learning opportunities for doctors of all specialties. Understanding your role in this highly specialised field will assist you in gaining maximal benefit from your time in ICM while ensuring the best outcomes for your patients. ⋯ This article provides tips and advice for doctors new to the specialty, and will be a useful guide for medical, surgical, and emergency medicine trainees before they begin working in the ICU for the first time. We provide a structured, systematic framework which can be used comprehensively to assess ICU patients.
