Dog Minute Ventilation Calculator
Calculate minute ventilation and adjust ventilator settings to target normal EtCO2 in mechanically ventilated dogs.
What Is the Dog Minute Ventilation Calculator?
Calculate minute ventilation and adjust ventilator settings to target normal EtCO2 in mechanically ventilated dogs.
Minute ventilation (tidal volume x respiratory rate) determines CO2 clearance. EtCO2 monitoring allows real-time adjustment of ventilator settings.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
Minute ventilation is the total volume of gas moved in and out of the lungs per minute — calculated as tidal volume multiplied by respiratory rate. Normal minute ventilation in dogs is 170–350 ml/kg/min. During mechanical ventilation or manual IPPV (intermittent positive pressure ventilation), the goal is to maintain normocapnia (PaCO₂ 35–45 mmHg). Hypoventilation (high PaCO₂) causes respiratory acidosis and CNS depression. Hyperventilation (low PaCO₂) causes respiratory alkalosis and cerebral vasoconstriction. Tidal volume for mechanical ventilation in dogs: 10–15 ml/kg at 8–20 breaths/minute. Inspiratory:Expiratory ratio should be 1:2 to 1:3 to allow adequate exhalation.
