Limited evidence is available regarding the role of high-flow nasal oxygen in the management of acute hypoxemic respiratory failure secondary to coronavirus disease 2019. Our objective was to characterize outcomes associated with high-flow nasal oxygen use in critically ill adult patients with coronavirus disease 2019-associated acute hypoxemic respiratory failure. ⋯ We observed an overall high usage of high-flow nasal oxygen in our cohort of critically ill patients with acute hypoxemic respiratory failure secondary to coronavirus disease 2019. Rates of endotracheal intubation and mortality in this cohort were on par with and certainly not higher than other published series. These findings should prompt further considerations regarding the use of high-flow nasal oxygen in the management algorithm for coronavirus disease 2019-associated acute hypoxemic respiratory failure.

Case Reports
Rescue of Nimodipine-Induced Refractory Vasoplegia With Hydroxocobalamin in Subarachnoid Hemorrhage: A Case Report.
We report a case of refractory vasoplegia after nimodipine administration that was unresponsive to triple vasopressor therapy and was rescued by IV hydroxocobalamin. ⋯ Nimodipine administration is a standard practice for patients with aneurysmal subarachnoid hemorrhage to reduce unfavorable outcomes from cerebral vasospasm. Although mild hypotension is a common side effect of nimodipine, in rare cases, it may become profound, leading to refractory vasoplegia. There is no evidence-base for reversal agents for nimodipine-induced vasoplegia, and this case is the first to demonstrate successful use of hydroxocobalamin as a potential rescue therapy. We also propose an algorithm for treatment of vasoplegia with consideration of medications that act on nitric oxide-mediated vasodilation and their side-effect profiles.

Case Reports
Convalescent Plasma Therapy in Four Critically Ill Pediatric Patients With Coronavirus Disease 2019: A Case Series.
Coronavirus disease 2019 is a pandemic with no specific therapeutic agents or vaccination. Small published case series on critically ill adults suggest improvements in clinical status with minimal adverse events when patients receive coronavirus disease 2019 convalescent plasma, but data on critically ill pediatric patients are lacking. We report a series of four critically ill pediatric patients with acute respiratory failure who received coronavirus disease 2019 convalescent plasma as a treatment strategy for severe disease.

To construct a highly detailed yet practical, attainable roadmap for enhancing the likelihood of neurologically intact survival following sudden cardiac arrest. ⋯ The likelihood of neurologically favorable survival following out-of-hospital cardiac arrest can improve substantially in communities that conscientiously and meticulously introduce a well-sequenced, highly choreographed, system-wide portfolio of both traditional and nonconventional approaches to training, technologies, and physiologic management. The commonalities found in the analyzed systems create a compelling case that other communities can also improve out-of-hospital cardiac arrest outcomes significantly by conscientiously exploring and adopting similar bundles of system organization and care.

To assess the early physiologic response to angiotensin-II treatment in patients with coronavirus disease 2019-induced respiratory failure and distributive shock. ⋯ Angiotensin-II treatment for coronavirus disease 2019-induced distributive shock was associated with rapid improvement in multiple physiologic indices. Angiotensin-II in coronavirus disease 2019-induced shock warrants further study.
