Pressure Cycled Ventilator

There are two main methods of ventilating subjects. Volume controlled ventilation uses either a Starling type pump comprising of a piston/cylinder arrangement which allows the volume and respiratory rate to be adjusted independently. The pressure controlled method employs a pressure sensor to determine the time of inspiration and expiration.

CWE SAR 830A/P

Standard Features

Dependable, all electronic ventilator
Pressure or Volume-cycled
Analog airway pressure signal
Wide tidal volume and rate adjustment
Expandable to large species
Multiple subject ventilation possible
Safe with anesthesia and oxygen

A built-in solid-state transducer monitors airway pressure. The operator simply dials-in the desired end-inspiratory pressure. During inspiration, airflow is introduced to the lungs until this pressure is reached, at which point inspiration is terminated. This mode is especially convenient with small subjects where accidental hyperinflation of the lungs can be a problem. An analogue output for the pressure signal is provided for external recording.
