Concern over the lack of adequate numbers of critical care ventilators to meet this demand led the U.S. Food and Drug Administration to authorize the use of anesthesia machines as critical care ventilators. The use of anesthesia machines for ventilating patients with COVID-19 is overseen by an anesthesia provider, but respiratory therapists may encounter their use. This article reviews the fundamental differences between anesthesia machines and critical care ventilators, as well as some common problems encountered when using an anesthesia machine to ventilate a patient with COVID-19 and steps to mitigate these problems.Clostridium difficile is a gram-positive anaerobic spore forming bacillus that can cause infection in a setting of antibiotic use. Pneumonia is a major cause of morbidity and mortality in an inpatient setting and is frequently associated with significant antibiotic administration. This study aims to compare the outcomes of C. difficile infection (CDI) with and without pneumonia to determine the impact of pneumonia in hospitalized patients with CDI. This population-based retrospective observational propensity matched analysis study uses data from the National Inpatient Sample database for the years 2016 and 2017. The primary outcomes were in-hospital mortality, total hospital charges, and mean length of stay. Secondary outcomes were the rates of sepsis, septic shock, non-ST elevation myocardial infarction (NSTEMI), acute renal failure, deep vein thrombosis, and pulmonary embolism. In-hospital mortality was noted to be higher in patients with pneumonia than those without (6.5% vs 1.2%, adjusted OR (aOR) 3.85; 95% CI 2.90 to 5.11, p less then 0.001). The following outcomes were more prevalent in patients with pneumonia compared with those without pneumonia sepsis (9.8% vs 1.8%,
