Indications for Use
The Asthma Monitor AM3/AM3 BT/AM3 GSM/G+ is an electronic measurement
device to monitor the lung function (determination of the respiratory ows and vol-
ume) with high reproducibility wherever and whenever there is a need of. The AM3
measures the ow during expiration serving for the calculation of further parameters
as FEV1.
The AM3 is used to monitor the respiratory status of adult human beings in the areas
of asthma, chronic obstructive pulmonary disorder and in areas like occupational
medicine, clinical trials and disease management.
The patient is informed of the results by numeric values for the selected parameters
(e.g. PEF, FEV1). Furthermore, a visual control unit, displayed in the form of trafc
lights, allows an immediate indication of the measurement based on criteria dened
by the patient’s physician.
The device saves the results of a measurement (always with date and time) automati-
cally in an internal database. In addition, questionnaire functionality can be called up
by the use of a software package (AMOS) to record e.g. the “Quality of Life” status.
When enabled, the AM3 can be programmed with a couple of questions, where the
patient can then select from a couple of different answers. This information is also
stored in the internal database and can be transmitted for evaluation to a standard
PC using the software package AMOS.
The AM3 is designed to replace an ordinary peak ow meter, diary and pencil by a
single system. Easy handling, sturdy and handy design allow the Asthma Monitor
AM3 to be used in healthcare, clinical and home use environments/settings.
US FEDERAL LAW RESTRICTS THIS DEVICE TO SALE BY OR ON THE
ORDER OF A PHYSICIAN. (Rx only)
The application of this system is restricted to trained users who can guarantee for the
correct usage of the device.
The AM3 is powered with a Lithium-ion battery. No energy is transferred to the
users.

The sensor is intended for single patient use, only. If the AM3 is passed
on to another patient, the AM surfaces will have to be cleaned and
disinfected with a disinfectant. See 8.4 for cleaning of housing.
See below for informa tion on disposal of a used sensor.
8. Cleaning
8.1 Cleaning of Sensor
To clean the rotary ow sensor, release and remove sensor, rinse it with mild
cleansing agent, e.g. Instruton E by ANTISEPTICA Dr. Hans-Joachim Molitor GmbH
according to instructions of manufacturer, and then rinse with clean distilled water.
Shake off any remaining water on the sensor. Air-dry and reinsert the sensor. Any
minor discoloration in the sensor does not affect the performance of the AM3.
The Cleaning of the sensor should be performed every week or more frequently if
often heavily polluted. Furthermore, it is recommended to exchange the rotary ow
sensory with a new one after one year of use or 2000 measurements. If the sensor
is heavily polluted frequently, the exchange with a new sensor should be performed
every six months or as required. If there are any doubts that the measurement values
are correct, the rotary ow sensor has to be exchanged immediately.
8.2 Checking the Sensor
If your AM3 does not measure accurately, exchange the sensor or contact the
responsible Monitor or ERT Customer Care Helpdesk.
DO NOT use alcohol or any type of household cleaner!
![](/img.php?id=3279088&img=bg17.png)
Page 23/40Version 02.01 • Date 19JAN2017
8.4 Cleaning of Housing
If the device is polluted or passed on to another patient, the AM surfaces have to
be cleaned and disinfected with a disinfectant. We recommend combined cleansing
and disinfecting agents with basic substance quaternary ammonium compound, for
example „Cleanisept Wipes“ by Dr. Schumacher GmbH.
The method of application provided by the disinfectant manufacturer have to be
considered.
8.3 Disposal of Sensor and Mouthpiece
It is absolutely vital to avoid the patient, medical assistant or sensor
becoming contaminated with sputum during disassembly of the
disposable sensor.
Therefore, release and remove the sensor by pulling the disposable sensor
downwards (see picture). Dispose of it immediately.

The Instructions for Use is regarded to be a part of the instrument,
and should always be kept on hand.
9. Safety Precautions AM3
The instruction manual describes the present state of the device/system including
software and accessories with regard to the fundamental requirements of the MDD
93/42/EEC. Exact adherence to the instructions issued is a prerequisite for perfect and
intended functioning of ERT instruments.
Deviation from Intended Use
Any non-observance of the procedures (such as preparing for the measurement and
methods, disinfecting procedures, use of accessories and replacement parts etc.)
described in the Instructions for Use results in a deviation from intended use.
In case of a deviation from intended use the operator/user has to supply proof of
meeting all corresponding fundamental requirements. This is possible by performing
a corresponding conformity assessment procedure within in-house manufacture (see
§ 12, paragraph 1 last sentence of MPG (= Medizinproduktegesetz/ Medical Products
Act).
The operator/user is, however, not only responsible for performing the conformity
assessment correctly but is also completely liable for defective products - i.e. the
operator/user is not only liable for his/her modication of the medical product.
ERT only guarantees for the safety, reliability and functioning of the device if:
- installation, extension, modications, and repairs are exclusively carried out by
personnel authorized for these tasks by ERT.
- the ambient conditions at the place of installation are suitable for the device.
- the device is used according to the Instructions for Use.
- Unpack your medical device. Please check if the unit is damaged. If so, do not use
it and return it for a replacement.
The user has to follow the instructions. If the user doesn’t obey
the safety precautions this can lead to hazardous situations which
can lead to injury or death of the patient and/or destruction of the
device.
![](/img.php?id=3279088&img=bg19.png)
Page 25/40Version 02.01 • Date 19JAN2017
Electrical Safety
The AM3 is powered from an internal Lithium-Ion rechargeable battery, the battery
can be charged over a direct plug-in power supply (unit).
Attention:
- Only the original power supply delivered with the AM3 must be used for charging
the device.
- Do not perform measurements if the AM3 is connected to another device.
- Data transfer is not permitted during measurement.
Patient Safety according to EN 60601-1
The subject has to keep a distance of at least 1,5 m from a connected modem or
notebook to avoid any contact with electrical voltage.
Valid for all ERT Devices
Additional equipment connected to medical electrical equipment must comply with
the respective EN or ISO standards (e.g. EN 60950 for data processing equipment).
Furthermore all congurations shall comply with the requirements for medical
electrical systems. Anybody connecting additional equipment to medical electrical
equipment congures a medical system and is therefore responsible that the system
complies with the requirements for medical electrical systems. Attention is drawn to
the fact that local laws take priority over the above mentioned requirements. If in
doubt, consult your local representative or the ERT Customer Care.
Radiated Interference
The ERT device meets the regulations according to EN 60601-1-2 regarding
interference radiated and received. It is recommended not performing
a measurement with the device directly next to other equipment or in
combination with other devices in a stacked form, as this may result in faulty
operation.
![](/img.php?id=3279088&img=bg1a.png)
Page 26/40 Version 02.01 • Date 19JAN2017
However, if performing a measurement is required in the manner described above,
the devices should be observed to ensure they work properly.
The device should not be installed in the vicinity of high-frequency devices, X-ray
equipment, motors or transformers with high installed power rating, since electric or
magnetic interference elds may falsify the results of measurements or make taking
measurements impossible. Due to this, the vicinity of power lines is to be avoided as
well.
Existing environmental interferences may cause deviations of the measuring values
without impairing the device’s function.
Therefore, it is recommended to keep a distance of about 2 meters from possible
error sources when using the device.
Use ERT approved accessories or spare parts for this medical device only. Use of
unapproved equipment can result in increased electromagnetic interference or
reduced electromagnetic immunity of the medical device and can lead to faulty
operation.
Other portable RF communication equipment (including their accessories, such as
antenna cables and external antennas) should not be spaced less than 30 cm (or
12 inches) from the parts and leads of the AM3. Failure to do so may result in a
reduction in the performance of the AM3.
Ambient Conditions
AM3 must not be operated in rooms or in the presence of ammable anaesthetic
mixture with air or ammable anaesthetic mixture with oxygen or nitrous oxide.
AM3 has to be effectively protected against moisture. Therefore, it is required that
the AM3 is always stored in the corresponding bag. The device corresponds to IP 22
degree of protection. Measurements in the rain or in the shower are not allowed.
Measuring Mode
As the combination with an IEC 60950-1 proofed PC or modem can lead to a sum-
mation of the leakage current, the AM3 must not be connected to a PC or modem
during the measurement.
![](/img.php?id=3279088&img=bg1b.png)
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 qualied 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.

Page 28/40 Version 02.01 • Date 19JAN2017
Putting the Device into Operation
Temperature changes may give rise to condensation in the device. Consequently, the
device has to adapt to the ambient temperature before putting it into operation.
Cleaning and Hygiene
Prior to every application, all parts which come in contact with the patient and which
are intended for reuse must be cleaned or disinfected (unless otherwise instructions
are available).
During cleaning, the AM3 must not be connected to a PC or modem.
Referring to humidity and water which may get into the device, AM3
corresponds to the safety degree IP 22. This means, the device can be cleaned with
a damp (in no case dripping wet) cloth which does not produce uff. More detailed
information can be found under “Cleaning”. Chemicals required for operation or
care of the unit have to be used in accordance with instructions of the manufacturer
and must always be stored, prepared and made available in specially marked vessels
to prevent any mistakes.
- massive pneumothorax (within the rst weeks)
- abdominal or thoracic surgery (depending on the ndings 1 to 4 weeks
postoperatively)
- surgery of the eyes, brain, or ears (variable, consultation with the surgeon)
- Special care must be taken when dealing with hemoptysis of unknown origin
Maintenance
The device doesn’t require to perform preventive inspection, maintenance and
calibration. No part of the AM3 should be replaced by the subject/doctor.
Use ERT approved accessories and spare parts for this medical device, only.
If the device/applied part has been exposed to extreme mechanical stress, a function

Page 31/40Version 02.01 • Date 19JAN2017
For the efcient and safe operation of your AM3, please read the following
information carefully.
Safety and Hazards
Do not operate the AM3 with wireless communication in areas where blasting is in
progress, where explosive atmospheres may be present, near life support equipment,
or any equipment which may be susceptible to any form of radio interference.
In such areas, the wireless communication module MUST BE POWERED OFF. The
AM3 with enabled wireless communication can transmit signals that could interfere
with this equipment. Do not operate the wireless communication module any
aircraft, whether the aircraft is on the ground or in ight. In aircraft, the wireless
communication module MUST BE SWITCHED OFF. When operating, the wireless
communication module can transmit signals that could interfere with various
onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. The wireless communication module may be used at
this time.
RF Safety
GENERAL
The AM3 uses a wireless communication module based on the 3G standard for
cellular technology. The 3G standard is spread all over the world and is the most
used telecommunication standard. The wireless communication module is actually a
low power radio transmitter and receiver. It sends out and receives radio frequency
energy. When you use your wireless communication application, the cellular system
which handles your transfers controls both the radio frequency and the power level
of your cellular modem.
9.2 Safety Precautions for Wireless Communication
Page 32/40 Version 02.01 • Date 19JAN2017
EXPOSURE TO RF ENERGY
There has been some public concern about possible health effects from using
wireless communication terminals. Although research on health effects from RF
energy has focused on the current RF technology for many years, scientists have
begun research regarding newer radio technologies, such as 3G. After existing
research had been reviewed, and after compliance to all applicable safety standards
had been tested, it has been concluded that the product was t for use. If you are
concerned about exposure to RF energy there are things you can do to minimize
exposure. Obviously, limiting the duration of your calls will reduce your exposure
to RF energy. In addition, you can reduce RF exposure by operating your cellular
terminal efciently by following the guidelines below.
EFFICIENT TERMINAL OPERATION
For your wireless communication terminal to operate at the lowest power level,
consistent with satisfactory transfer quality:
Do not hold the device when the transfer is in progress. Holding the antenna affects
transfer quality and may cause the wireless communication module to operate at a
higher power level than needed.
General Safety
ELECTRONIC DEVICES
Most electronic equipment, for example in hospitals and motor vehicles, is shielded
from RF energy. However, RF energy may affect some improperly shielded electronic
equipment.
MEDICAL ELECTRICAL EQUIPMENT
Turn your wireless communication module OFF in health care facilities when any
regulations posted in the area instruct you to do so. Hospitals or health care facilities
may be using RF monitoring equipment.
