The Harvard Apparatus Large Animal Volume Controlled Ventilator is suitable for ventilating a single animal from 1.5 to 50 kg. It has adjustable tidal volume from 30 to 700 ml/stroke and an adjustable respiratory rate from 7 to 50 breaths/minute. 

This is the workhorse of the Harvard Apparatus Volume Controlled Ventilators. There are literally thousands of these Ventilators in use in leading research laboratories throughout the world.

  • For animals from 1.5 to 50 kg (3.3 to 110 lb) in weight 
  • Volume adjustable from 30 to 750 cc/stroke 
  • Variable Inspiratory: Expiratory Ratio

Note that the volume adjustment is made on the piston shaft, and that therefore accurate volume adjustment cannot be made while the ventilator is running. However, the rate and the I:E % can be varied while the ventilator is running. Air/gas valving is by the four port system with separate ports for gas inlet, gas outlet (to animal), gas return (from animal), and ventilator exhaust.

The gas inlet can be used to supply air or any non-flammable gas supply. Like the other Harvard mechanical ventilators, attachment of the ventilator exhaust to a column of water can be used to produce a positive and expiratory pressure (PEEP).
