AeroVent Collapsible Holding Chamber (CHC)

Holding Chamber (CHC) Maintains the ventilator closed circuit integrity. Designed to be placed in the inspiratory limb of the ventilator circuit. The collapsible unit is easy to connect and has less disruption for patient comfort. Can be used with most pMDIs, including those with incorporated dose counters.

The AeroVent Collapsible Holding Chamber provides for easy and quick aerosol drug delivery without breaking the ventilator circuit during continuous mechanical ventilation. When not in use, the AeroVent CHC can be closed to become part of the ventilator circuit.

A study conducted by Coleman et al concluded that spacers with MDIs were twice as efficient in delivering the percentage of starting dose than nebulizers. These results have been reproduced in several studies.

Another study conducted by Marik et al concluded in a study using the AeroVent CHC and albuterol that 38% of the dose was delivered with AeroVent CHC vs. 9% with a typical right-angle adapter. They further concluded that right-angle adapter ports should not be used to deliver bronchodilators to ventilated patients
