Relationships between PaO2/FiO2, respiratory system compliance, and ventilatory ratio in COVID-19 ARDS patients. In the COVID-19 cohort, respiratory system compliance and its PBW-indexed value were linearly related to PaO2/FiO2 ratio (upper panels). Ventilatory ratio was not related to PaO2/FiO2 ratio nor to respiratory system compliance (lower panels). CRS, respiratory system compliance; PBW, predicted body weight
