Information Services
– Process in which flow is divided into very small . Flow is volume/time – end result is volume.

- Device that provides reverse of integration. Flow is obtained from volume signals

Data Backup- Temporary , permanent patient files, storage

Data Interface – Allows for both access to and of equipment during testing
12 bit converters – used most for volume and flow measurements

Converter speed – important for tests that require signal changes like FVC

Software – contains instructions stored in memory of computer. Most software contains interpretation programs that utilize algorithims

Mass Storage Devices – Hard Drives, stores lots of info
CPU – Performs most functions in software

Resolution- change that can be measure by computer. Calculated via: Volume range (liters), Signal range (volts), A/D converter (bits)
