What type of vent do you use? LifeCare (now owned by Respironics) has
several different type/size cuirasses for use with their negative pressure
systems. Also, our daughter uses a cuirass manufactured by Breazy Medical
to go with her Hayek Oscillator (also negative pressure). The LifeCare
Cuirass has a central access to the cuirass, the Hayek cuirass has two
access ports of smaller diameter.
