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 note below documents the steps required for this process.

NOTE: An adapter is available (276-0951-001) for connection of the Hans Rudolph Pneumotach to the Bias Flow.

Hardware option:
