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.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

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

Each component has a specific meaning:

  • Simplified formula incorporating RR — The simplified formula incorporating rr recorded for the scenario being assessed.
  • Vt — The vt recorded for the scenario being assessed.
  • PEEP — The peep recorded for the scenario being assessed.
  • Peak pressure — The peak pressure recorded for the scenario being assessed.

Note: Interpret the mechanical power result against the thresholds and context described above.

How to Use

Enter the simplified formula incorporating RR, Vt, PEEP, peak pressure for the scenario you are assessing. 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. Use the mechanical power result to inform your calculation.
