  1. BMI: body mass index; COPD: chronic obstructive pulmonary disease; MV: mechanical ventilation; SOFA: sepsis-related organ failure assessment; PSV: pressure support ventilation; CRS: respiratory system compliance; RRS: respiratory system resistance. CRS and RRS were recorded during PAV+. PSL: pressure support level; PEEP: positive end-expiratory pressure; PEEPi: intrinsic positive end-expiratory pressure; AHF: acute heart failure
