Abstract
A moisture sump integrated into a carbon dioxide absorber canister provides a collection reservoir for condensate from a patient ventilator system when the carbon dioxide absorber canister is attached to the ventilator system. The volume of the moisture sump is appropriately sized so that the time interval required to collect a maximum amount of condensate interval is not more than the life expectancy of the carbon dioxide absorbing material contained within the canister. The moisture sump allows condensate management of difficult to drain areas such as the inlet to the expiratory check valve of a ventilator system. The removal of the carbon dioxide absorber canister by a patient attendee to replace the carbon dioxide absorbing material ensures that the condensate collected by the integral moisture sump is eliminated from the patient ventilator system.
