Pressure Reservoir
Small animal pressure reservoir
The pressure reservoir is divided into two sections, negative and positive. The positive reservoir is used to inflate
the lungs at the configured inspiration flow rate. The negative reservoir section is used to slowly deflate the lungs
at the configured slow expiration flow rate during PV tests, and to deflate the lungs as quickly as possible during FV
tests.
The pressure in both reservoirs is set on the Valve Control Module.
The pressure reservoir is available in two sizes. Small animal (SA) and large animal (LA). The small animal model is
used for mice, rats, and guinea pigs. The large animal model is used for rabbits, ferrets, and small primates.
