Details

The Bear Cub 750 Ventilator for small animals offers three layers of safety for lung protection. Providing flow cycling, adjustable pressure limit and volume limit.

Bear Cub Infant Ventilator is designed to accomodate a range of animals from the small neonate to the 30 kg pediatric patient. The 750 incorporates Integrated Synchronized Ventilation, Tidal Volume Monitoring and Independent Base & Inspiratory Flows for clinical flexibility in a compact design. Volume Limit™ provides the clinician with an additional guidance tool during pressure ventilation as it enhances volume management and establishes an upper boundary for deliverable tidal volumes during mechanical breaths.

The Bear Cub 750 provides responsive and accurate proximal airway flow triggering and volume monitoring. The improved heated wire anemometer flow sensor provides accuracy in the breath-to-breath measurement of spontaneous and mechanical inspiratory and expiratory tidal volume and percentage of tube leak.

Flow triggering at the proximal airway offers the sensitivity and response time that is required for tiny premature infants with rapid respiratory rates. This results in consistent ventilator-patient synchrony and decreased work of breathing in infants.

The Ventilator Graphics Monitor can be used interchangeably between different Bear Cub 750 Ventilators. This monitor interfaces with the ventilator and uses the flow measurements from the proximal airway flow sensor and pressure measurements from the proximal pressure line to monitor pressure, flow and volume waveforms. Pressure and Flow Volume Loops may also be displayed.
