A Bilateral Diaphragmatic Paralysis Post-COVID-19 Infection: A Case Report and a Review of the Literature.

The diaphragm is the essential respiratory muscle, and damage can significantly impede a human's capacity for blood oxygenation. During inspiration, the diaphragm domes permit the pleural cavity to expand. Whenever this process is disrupted, it results in decreased thoracic expansion and, as a result, hypoventilation.

Intensive care units with low versus high volume of myocardial infarction: clinical outcomes, resource utilization, and quality metrics.

Background: The volume-outcome relationship associated with intensive care unit (ICU) experience with managing acute myocardial infarction (AMI) remains inadequately understood.

Methods And Results: Within a multicenter clinical ICU database, we identified patients with a primary ICU admission diagnosis of AMI between 2008 and 2010 to evaluate whether annual AMI volume of an individual ICU is associated with mortality, length-of-stay, or quality indicators. Patients were categorized into those treated in ICUs with low-annual-AMI volume (≤50th percentile, <2 AMI patients/month, n=569 patients) versus high-annual-AMI volume (≥90th percentile, ≥8 AMI patients/month, n=17 553 patients).
