Variation of mechanical power in function of variation of driving pressure. In this figure, the variation of mechanical power (ΔMP) in J/min changes in function of the variation of driving pressure ΔP (ΔΔP) with (1) fixed respiratory rate to 10 breaths/min on the left, and (2) variable respiratory rate according to the formula by Costa et al. on the right. The figure depicts the variation at different compliances of the respiratory system (20, 30, 40, 50, 60 mL/cmH2O). Basal MP is assumed to be calculated on a tidal volume (VT) of 7 ml/kg of predicted body weight (70 kg) and PEEP = 0 cmH2O, according to the formula of MP in pressure control ventilation = 0.098 × respiratory rate × VT × (PEEP + ΔP)
