Background and description:

The physical aspects of the Body Plethysmograph (BPD), which includes the instrumentation used to conduct plethysmography tests with PLUS/2000 software, are referred to as hardware. The CPL system is another Collins instrument in the PLUS/2000 family that performs a pulmonary function and exercise testing.

The Collins Body Plethysmograph is a pressure chamber that measures lung volume, airway resistance, and other parameters. Within the sealed chamber, the patient performs breathing maneuvers as directed by the operator. The plethysmograph includes a peumotach and three transducers for measuring changes in box pressure, mouth pressure, and flow at the mouth during maneuvers. Section Three of this manual explains the basic theory for users who have never used a pressure plethysmograph before. Spirometry maneuvers, FVC and MVV, as well as PImax/PEmax, are also performed by the Collins BPD.

Manuals

There are two manuals for this system:

a. The BPD Instruction Manual, which you are now reading

b. The PLUS/2000 Software Manual.

The BPD manual describes system installation, testing setup, maintenance and troubleshooting.

The PLUS 2000 manual describes all aspects of the software, including patient testing, configuration, database utilities and reports.
