What mechanical power level is considered safe?

Mechanical power >17 J/min is associated with increased VILI risk and mortality in ARDS, while power <12 J/min is generally considered lower risk when normalized to lung volume.

How is mechanical power reduced in practice?

Mechanical power is reduced by lowering respiratory rate, tidal volume, PEEP, or inspiratory flow rate, though these must be balanced against oxygenation and CO2 clearance goals.

Mechanical Power — Ventilator-Induced Lung Injury Risk

Calculate mechanical power (MP) transferred to the respiratory system per breath cycle to assess ventilator-induced lung injury (VILI) risk using the simplified formula incorporating RR, Vt, PEEP, and peak pressure.
