Calibration of the PhysioTel Digital L11R versus a Pneumotach requires acquisition of both respiratory signals in a synchronized manner. It also requires calibration of the pneumotach signal versus a reference.

The technical notes below document the steps required for these processes depending on the hardware being used for Pneumotach data collection:

Available hardware options:

1. Hans Rudolph amplifier with DSI ABDC amplifier
2. Validyne transducer with DSI Carrier amplifier
