From: An appraisal of respiratory system compliance in mechanically ventilated covid-19 patients
Association of airway inspiratory plateau pressure with static respiratory system compliance. Linear Mixed model analysis of the association of respiratory system compliance with airway inspiratory plateau pressure during the first 7 days of mechanical ventilation (grey-scale coded bar for day 1 through 7 is reported on the right section of each graph and in parenthesis is reported the number of analysed patients). Fitted line of the model is depicted, and the upper and lower lines display the 95% predictive interval. Analysis is adjusted for body mass index. The model highlights significant association between respiratory system compliance and airway plateau pressure (estimated decrease − 0.22 cmH2O/L, 95% CI − 0.23 to − 0.21, p < 0.001), but based on the model prediction, airway plateau pressure remained predominantly below 30 cmH2O
