Ventilatory Ratio in Hypercapnic Mechanically Ventilated Patients with COVID-19-associated Acute Respiratory Distress Syndrome.

The article focuses on case series highlighting ventilatory ratio in hypercapnic mechanically ventilated patients with COVID-19–associated acute respiratory distress syndrome (ARDS) and their individualized ventilation strategies. It mentions hypercapnia was common in patients with COVID-19–related ARDS with low VT ventilation. It also mentions increased pulmonary dead space reflects the inefficiency of the lungs to eliminate carbon dioxide which may lead to hypercapnia.
