Geometrical view of mechanical power for volume-controlled ventilation. Left pane (a) l: the violet contoured trapezoid represents the mechanical power as calculated with the reference formula (Eq. 1). Right panel  (b): the violet contoured trapezoid represents the mechanical power as calculated with our unadjusted surrogate (Eq. 3). The violet-filled triangle represents the bias (Eq. 4) between our unadjusted surrogate (Eq. 3) and the reference formula (Eq. 1)
