ERT AM3 - Interface, Supervision, and Contraindications

Page 27/40Version 02.01 • Date 19JAN2017
Interfaces
The AM3 must only be connected to a PC that corresponds to EN 60950 standards.
If the connection cable is defective, it has to be replaced by a new one. The operator
must not touch the Interfaces during measurement.
Medical Supervision
A qualied physician has to reassess all AM3 measurements. An interpretation by the
AM3 is only important if it is considered in connection with other clinical ndings.
Contraindications and possible adverse effects:
According to ‘‘ATS/ERS TASK FORCE: STANDARDISATION OF LUNG
FUNCTIONTESTING’’ (ERS Journals Ltd 2005) performing lung function tests can be
physically demanding for a minority of subjects. It is recommended that subjects
should not be tested within 1 month of a myocardial infarction.
In rare cases spirometry testing can lead to syncope due to extensive exhalation.
Furthermore, the following conditions probably lead to suboptimal lung function
results:
- Chest or abdominal pain of any causes,
- Oral or facial pain exacerbated by a mouthpiece,
- Stress incontinence,
- Dementia or disorientation.
According to “German Airway League, German Respiratory Society and German
Society of Occupational and Environmental Medicine, 2015” (S2 guideline
“Spirometry”) forced manoeuvers should not be performed in case of
- acute, life threatening diseases of every description (e.g. acute fulminant
pulmonary embolism, large ascending aortic aneurysm, tension pneumothorax)
Should the measuring values of the AM3 be changed after a longer period of use, a
new sensor should be used.
