Calibration Check - CareFusion SpiroUSB Manuel D'utilisation

Calibration Check

The spirometer is calibrated to read in liters at body temperature,
Barometric Pressure Saturated with water vapour (BTPS).
The calibration should remain stable indefinitely, unless the
transducer is physically damaged, and the unit should not require
re-calibration. However, to ensure the correct functioning of the unit
we do recommend that a calibration check is performed after the
transducer was removed for cleaning.
Pressing the 'Verify Calibration' button in SPCS invokes the start of a
device search and the option Calibration Check. The device search
effectively scans the PC's commas/usb ports for any attached
device. On finding a device the screen will change to the main verify
calibration test screen. The option to perform an expiratory only and
expiratory and inspiratory calibration check, and a single volume
calibration or more advanced calibration check at three separate
flow rates, can be chosen in the calibration screen.
Connect a 3L syringe to the transducer with the minimum of
adapters and empty it by pushing the handle fully in.
Note: It is recommended that the transducer is disinfected prior to a
calibration check or a MicroGard® filter is used during the procedure.
