The ventilator is a pressure, volume, and flow machine — and so is the lung. These calculators span lung-protective tidal volume selection, compliance and resistance measurement, weaning-readiness indices, and mean airway pressure targets. Use them at the bedside to set safe parameters and interpret waveform data.

Total air moved per minute — tidal volume × respiratory rate.
Effective ventilation after subtracting dead space.
Lung-protective tidal volume from ideal body weight.
Inspiratory-to-expiratory time ratio on the ventilator.
Lung/chest-wall stiffness from plateau pressure.
Compliance during airflow, including airway resistance.
Resistance to airflow from the peak-plateau pressure gap.
Average pressure across the breath cycle — drives oxygenation.
Weaning-readiness index — rate over tidal volume.
Respiratory muscle strength for weaning readiness.
Composite ARDS severity score used in ECMO discussions.
