Diffusion of oxygen and carbon dioxide occurs passively, according to their concentration differences across the alveolar-capillary barrier. A significant association of DS with both death (HR 1.204 CI 1.019–1.423 p = 0.029) and discharge (HR 0.434 CI 0.414–0.456 p \(< 0.001\)) was noticed even when correcting for confounding factors (age, sex, chronic obstructive pulmonary disease, diabetes, PaO \(_\) ratio), is easy to collect and focuses on physiological quantities directly measured from the patient.Gas exchange between the alveoli and the pulmonary capillary blood occurs by diffusion, as will be discussed in the next chapter. The final population consisted of 401 patients from seven ICUs. A competing risk Cox proportional hazard model was applied to test for the association of DS with two competing outcomes (death or discharge from the ICU) while adjusting for confounders. Retrospective cohort study on data derived from Italian ICUs during the first year of the COVID-19 epidemic. Here, we explore the association between a surrogate measure of dead space (DS) and early outcomes of mechanically ventilated patients admitted to Intensive Care Unit (ICU) because of COVID-19-associated ARDS. Physiologic dead space is a well-established independent predictor of death in patients with acute respiratory distress syndrome (ARDS).
