12 Hygiene and instrument maintenance

When used correctly the EasyOne-CS requires minimal maintenance and service.
When you use the spirette™ respiratory tube, you do not need to clean the instrument. Instead of
cleaning, you simply change the respiratory tube. In order to ensure absolute hygiene, we recommend
that the spirette™ be used only once per patient.
Caution:
Always exchange the spirette™ if you suspect the risk of infection. This is the only
way of absolutely preventing transmission of diseases.
Use a damp cloth to clean the spirometer housing and the base unit. Use a soft cloth and alcohol (e.g.
isopropyl alcohol) for particularly thorough cleaning.
Caution:
Avoid fluid penetrating the spirette™ holder or the inside of the instrument when
cleaning the spirometer.
To change the batteries please procede as follows: Open the battery lid on the back side of the instru-
ment. Remove the old batteries. Insert two new alcaline batteries (Type AA, 1.5V). Put the battery lid
back on. Ensure that the battery compartment cover is firmly closed since patient safety may depend
on it.
In the event of instrument malfunction, please contact your EasyOne-CS dealer or call the After-Sales
Servicing Department of GE Medical Systems Information Technologies
(http://www.gehealthcare.com).
Please proceed as follows if you wish to check whether your instrument is functioning correctly:
1. Check calibration. Please read Chapter 13.
2. Conduct a spirometry test on yourself.
3. Ensure that the results are plausible and that you can print out the report as required.
Consult your EasyOne dealer if you encounter problems with one of these points.

13 Calibration Check

Calibration of the instrument can be checked with a syringe using the calibration check function. The
American Thoracic Society (ATS) recommends that calibration be checked every day. The EasyOne-CS
spirometer requires no calibration, even if used frequently.
To perform a calibration check, you need the optional ndd calibration adapter and an optional calibra-
tion syringe (order number 2030431-010), in addition to the spirometer and a spirette™. Ensure that
the correct syringe volume is entered in the instrument's configuration setting (see also Chapter 8).
Proceed as follows:
•
Choose item "Check calibration" in the main menu.
•
Connect the spirometer as shown below using the calibration adapter and the syringe. Ensure
that the piston is fully inserted and at the stop position.
