Lung recruitment maneuvers for adult patients with acute respiratory distress syndrome. The recommendation for intermittent boluses of NMBAs or a continuous infusion of NMBAs to facilitate lung protection may require a health care provider to enter the patients room frequently for close clinical monitoring. Probiotic supplements can be used as one part of an immune-boosting protocol to help reduce the likelihood of coronavirus infection. Elahi further added, "Because of that, we thought one potential mechanism might be that Covid-19 impacts red blood cell production.".
