Dog Tidal Volume Calculator
Calculate the correct tidal volume and ventilation parameters for mechanical ventilation in dogs based on body weight.
What Is the Dog Tidal Volume Calculator?
Calculate the correct tidal volume and ventilation parameters for mechanical ventilation in dogs based on body weight.
Mechanical ventilation in anesthetized or critically ill dogs requires precise tidal volume settings to prevent barotrauma and volutrauma. Tidal volume that is too high causes lung injury; too low causes atelectasis. This calculator provides evidence-based ventilation parameters for dogs.
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
Tidal volume (VT) for mechanical ventilation in dogs is standardly calculated at 10–15ml/kg for healthy lungs, or 6–8ml/kg for lung-protective ventilation in ARDS/pneumonia cases. Respiratory rate is typically set at 8–15 breaths/minute to achieve a minute ventilation of 150–250ml/kg/min. Peak inspiratory pressure should ideally be kept below 20cmH2O. I:E ratio is typically 1:2 for most patients.
