Mechanical Power Calculators

Mechanical Power in Volume Controlled Ventilation with constant flow (mM) (Daoud, et al)

Equation: MP = 0.13 (mM) + 2.48

Mechanical Power in Pressure Controlled Ventilation

(mM) (Daoud, et al)

Equation: MP = 0.15 (mM) + 3.79

Reference: Mean airway pressure – Minute ventilation product (mM): A simple and universal surrogate equation to calculate mechanical power in both volume and pressure controlled

Mechanical Power in Volume or Pressure Controlled Ventilation

(mM) (Daoud, et al)

Equation: MP = 0.13 (mM) + 3.41

Reference: Mean airway pressure – Minute ventilation product (mM): A simple and universal surrogate equation to calculate mechanical power in both volume and pressure controlled ventilation

Note: This equation might overestimate MP in VCV and underestimate MP in PCV especially at high levels on mean airway pressures and minute ventilation

Mechanical Power in Volume Controlled Ventilation with constant flow (Gattinoni, et al)

Equation: MP = 0.098 x RR x VT x (𝑃𝑝𝑒𝑎𝑘 − (𝑃𝑝𝑙𝑎𝑡 − 𝑃𝐸𝐸𝑃) 2)

Mechanical Power in Pressure Controlled Ventilation

(Becher, et al)

Equation: MP = 0.098 x RR x VT x (∆P_insp + PEEP)
