Values are stated as mean (SD). VT, tidal volume; VT PBW, tidal volume per predicted body weight;[9] CRS = respiratory system compliance, DAP = mean diastolic arterial blood pressure, MAP = mean arterial pressure, PEEP = positive end-expiratory pressure, PetCO2 = end-tidal carbon dioxide partial pressure, PIP = peak inspiratory pressure, SAP = mean systolic arterial blood pressure, VF = ventilation frequency; CO, cardiac output (calculated by the multiplication of the stroke volume of the comparative literature analysis [supplemental content; http://links.lww.com/MD/F645] and the respective individual heart rate). IQR, interquartile range. For data that were not normally distributed (∗), values are given in median (IQR).
