Calibration Check - Vyaire SpiroUSB Manual De Funcionamiento

Calibration Check

The spirometer is calibrated to read in litres 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 Calibtration Check. The device
search effectively scans the PC's comms/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.
