variable tidal volume ventilation (V-VCV)
The initial tidal volume was set at 6-8 ml/kg IBW according to the Ideal Body Weight (IBW).The maximum tidal volume (Vt\_max) and minimum tidal volume (Vt\_min) were set at 10-20% of the basal tidal volume (Vt\_base). Respiratory Rate 12. Inspiratory Flow Rate (IFR) 60L/min, Inspiratory to Expiratory Ratio (IER) 1:2, Positive End-Expiratory Pressure (PEEP) 5cm water column, and Inhaled Oxygen Concentration (FiO2) 41%.
pressure-regulated volume-controlled ventilation (PRVC)
The initial tidal volume was set at 6-8 ml/kg IBW according to the Ideal Body Weight (IBW), the upper limit of peak inspiratory pressure was 30 cmH2O, the maximum tidal volume (Vt\_max) and the minimum tidal volume (Vt\_min) was set at 10-20% of the base tidal volume (Vt\_base). Respiratory Rate is 12, Inspiration to Expiration Ratio is 1:2, Positive End-Expiratory Pressure (PEEP) is 5cmH2O, and Inhaled Oxygen Concentration (FiO2) is 98%.
conventional volume-controlled ventilation (C-VCV)
The initial tidal volume was set at 6-8 ml/kg IBW according to the Ideal Body Weight (IBW).The maximum tidal volume (Vt\_max) and minimum tidal volume (Vt\_min) were set at 10-20% of the basal tidal volume (Vt\_base). Respiratory Rate 12. Inspiratory Flow Rate (IFR) 60L/min, Inspiratory to Expiratory Ratio (IER) 1:2, Positive End-Expiratory Pressure (PEEP) 5cm water column, and Inhaled Oxygen Concentration (FiO2) 98%.
pressure-controlled ventilation (PCV)
The inspiratory pressure level is set, usually with an initial value of 20 cmH2O, a respiratory rate of 12, an inspiratory/expiratory ratio of 1:2, a positive end-expiratory pressure (PEEP) of 5 cm water column, and an inspired oxygen concentration (FiO2) of 98%.
