MP timeline. Physiological foundations are based on experimental studies: A. The key role of PEEP: the energy required to move the lung from its resting position (FRC) to the end-inspiratory volume, is the sum of the static component (due to PEEP) and the elastic component (due to VT). B. Iso-MP achieved adjusting TV or RR or PEEP is responsible for the iso-damage to the lungs. C. A MP value between 12 and 4–7 J/min was associated with the lowest injury assessed using anatomical and physiological variables. Epidemiological validation: To date the MP has been studied using epidemiological data, assessing the association between MP and mortality to identify a safe MP threshold. Several power formulas have been proposed for controlled and spontaneous ventilation. Personalization: In the future we envisage that the protective value of MP may be calculated for each individual patient (personalised) in relationship to anatomical or physiological characteristics. The total MP could therefore be normalised based on anthropometric values or functional values in normal subjects or ventilated patients with normal lungs. FRC: functional residual capacity, MP: mechanical power, PEEP: positive end-expiratory pressure, PEEP vol: Volume related to PEEP, VT: tidal volume, RR: respiratory rate
