Abstract
A ventilator breathing circuit is provided with an inline axially extensible inhalation chamber. Telescoping conduits are disposed within the chamber and normally are in fluid communication. The chamber comprises a pleated outer shell so that it may be axially extended upon separation of the telescoping conduits. A receptacle is provided opening into the chamber for receiving a metered dose inhalation medication cannister. In addition, an air leakage path is provided from the chamber which is designed to be covered manually during use, but which will provide an audible signal if the chamber is left in extended position and unattended.
