Lippincott Nursing Pocket Card - February 2021
Patients with severe symptoms of COVID-19 pneumonia often go on to develop acute hypoxemic respiratory failure and some will develop acute respiratory distress syndrome (ARDS) (Auwaerter, 2020). Critical care clinicians have managed ARDS for years; however, COVID-19 ARDS is different from the typical ARDS we’ve known.
Critical COVID-19 ARDS or respiratory failure requiring ventilation, sepsis or septic shock
The severity of the ARDS is defined by the degree of hypoxemia, which is calculated as the ratio of arterial oxygen tension to fraction of inspired oxygen (PaO2/FiO2). ARDS can be classified as mild, moderate or severe based on the Berlin definition of ARDS (Ranieri et al., 2012).
