Intrapulmonary and Intracardiac Shunts in Adult COVID-19 Versus Non-COVID Acute Respiratory Distress Syndrome ICU Patients Using Echocardiography and Contrast Bubble Studies (COVID-Shunt Study): A Prospective, Observational Cohort Study.

Objectives: Studies have suggested intrapulmonary shunts may contribute to hypoxemia in COVID-19 acute respiratory distress syndrome (ARDS) with worse associated outcomes. We evaluated the presence of right-to-left (R-L) shunts in COVID-19 and non-COVID ARDS patients using a comprehensive hypoxemia workup for shunt etiology and associations with mortality.

Design: Prospective, observational cohort study.

Assessing on-line medical education resources: A primer for acute care medical professionals and others.

The internet is increasingly used to propagate medical education, debate, and even disinformation. Therefore, this primer aims to help acute care medical professionals, as well as the public. This is because we all need to be able to critically appraise digital products, appraise content producers, and reflect upon our own on-line presence.
