disinfection and cleaning are performed in the way and with
the frequency described;
• any modification or fixing is carried out by qualified
personnel;
• the environmental conditions and the electrical plants
where the device operates are in compliance with the
specifications of the manual and the present regulations
concerning electrical plants. In particular grounding
reliability and leakage current suppression can only be
assured when the device three – wire receptacle is connected
to a yellow - green return connected to earth ground.
Attempting to defeat the proper connection of the ground
wire is dangerous for users and equipment.
3. Before powering the system, check the power cables and the
plugs. Damaged electrical parts must be replaced
immediately by authorised personnel.
4. The battery charger sold with Pony FX must be used only to
re-charge the battery. If you would like to perform test with
Pony FX connected to the mains, use the medical version
battery charger (see Installation chapter).
5. Cleaning residue, particulates, and other contaminates
(including pieces of torn or broken components) in the
breathing circuit pose a safety risk to the patient during
testing procedures. Aspiration of contaminates can
potentially be life-threatening. You must follow all the
cleaning procedures in System Maintenance, and you must
thoroughly inspect the components after cleaning and before
each patient test.
6. This device is not suitable for use in presence of flammable
anaesthetics. It is not an AP nor an APG device (according to
the EN 60 601-1 definitions).

C02388-01-05 Pony FX battery charger*
C02383-01-05 Pony FX battery charger, medical grade*
* Other battery charger with different plugs (Australia, UK,
USA) available on request.
The standard packaging of the Pony FX contains the first charger.
This one can be used only to charge the device battery. It is not
allowed performing tests with Pony FX connected to the mains.
In order to perform tests also when the device is connected to the
mains, use the medical grade battery charger (C02383-01-05),
compliant with the medical devices Standard.
Connect the battery charger to the Pony FX unit through the
connector with the symbol by side.
Near the keyboard, a led indicates the battery status:
Green led In charge
Orange led Full charged

• Very low battery, because of the unit has been not used for a
long time. The led switches to green after some time of
charging. Please fully charge the unit.
• Failed battery. Please contact the technical support.
Note: The first time you use the device, charge the battery for at
least 12 hours, even if the led indicates the completion of the
charge before the time elapsed.
Connect the flowmeter to the Pony FX
The Pony FX can operate with two types of flowmeters:
• Turbine flowmeter
• Pneumotachograph (disposable)
The turbine flowmeter
It is made of a handle (the reader)
with a hole, in which it is placed the
turbine.
The air passing through the helical
conveyors, takes a spiral motion
which causes the rotation of the
turbine rotor. The rolling blade
interrupts the infrared light beamed
by the two diodes of the reader.
Every interruption represents 1/4
turn of the rotor, this allows to
measure the number of turn in the
time.
It is connected to the unit through
the Turbine connector.
For hygienic reasons, we strongly
recommend the use of a bacterial
filter, to be connected as in the
picture by side.
Note: While inserting the turbine, be sure to push the turbine up
to touch the end of the reader.
Chapter 3 - Installation - 31
The pneumotachograph
It is disposable, and measures the flow detecting the difference of
pressure at the two sides of a membrane.
It is connected to the unit connecting the two tubes to the P+ e Pconnectors.
Connect the Pony FX to the PC
The Pony FX can be connected to the PC in order to transfer and
store the performed tests, to back-up the data on a different unit
(HD, floppy, CD ROM), to analyse the tests or to perform the
tests sending the controls directly from the PC.
If the PC connected to the Pony FX is placed within the patient
area (according to the IEC 60601-1-1 norm), the PC has to be
made compliant with the IEC 60601-1-1 norm by means of an
isolation transformer.
The PC is connected to the Pony FX unit, through an USB
connection, to the USB port with the symbol by side.
If the PC does not have an USB port, it is possible to use a
RS232 serial connection.
The first time you connect the Pony FX to the PC through an
USB connection, you will be requested for the drivers. Install
them from the installation CD.
Connect the Pony FX to an external printer
The Pony FX can be directly connected to an external printer in
order to print the performed tests on a different paper.
If the printer connected to the Pony FX is placed within the
patient area (according to the IEC 60601-1-1 norm), it has to be
made compliant with the IEC 60601-1-1 norm by means of an
isolation transformer.
The printer is connected to the Pony FX unit, through an USB
connection, to the USB port with the symbol by side.

Logic of the keyboard
The logic of the keyboard follows these rules:
• If the current input field (the one with the cursor) allows an
alphanumeric input (for example, name, company,…), you
have to follow these instructions in order to enter the
characters:
⇒ A repeated pressure of a key scrolls the available
characters for that key until another key is pressed or it
elapses 1 second.
⇒ If you wait more than 1 second or if you press another
key, you confirm the input and the cursor moves 1 place
towards right.
For example, in order to enter the string “BB4” you have to
press the following keys:
<wait>
The keys will enter the character first (letter or signs), and
then the digit.
• Pressing the Left key, the cursor moves towards left, deleting
the characters.
For some fields, you have to select an option from a
predefined list. In these cases, this key allows scrolling
backwards the list.

Forced Vital Capacity (pre)
FVC is a reference test to verify obstructive (airflow limitations)
and restrictive disorders (lung volume limitations). To achieve
good test results it is fundamental a good manoeuvre (quality
control messages, real time plots …)
The main parameters measured during FVC tests are:
FVC Forced Vital Capacity
FEV1 Forced Expiratory Volume in 1 second
FEV1/FVC% FEV1 as a percentage of FVC
PEF Peak Expiratory Flow
FEF25-75% Forced mid-Expiratory Flow
The two representative plots are the Flow/Volume and
Volume/Time loops.
By comparing FVC, FEV1 and FEV1/FVC% values the software
allows an automatic interpretation concerning the levels of
obstructive and/or restrictive disorders.
Perform a FVC (pre) test
1. Select Forced Vital Capacity pre from the Test menu and
wait for the green led is prompted on the right side of the

Maximum Voluntary Ventilation
Test for assessing the maximum ventilatory capacity. In the past,
it was commonly performed during routine PF tests, however its
clinical use declined over the years. Today MVV test is most
commonly performed as part of the exercise tolerance tests,
where it is used as an index of maximum ventilatory capacity.
Test consists in breathing in and out deeply and rapidly for 12, 15
seconds. The expired volume during this short period is then
extrapolated

Bronchial Provocation Test
Bronchodilator test
Note: Read
carefully the
contraindications
in Chapter 1.
Bronchodilators are administered routinely in the PFT laboratory
to determine whether airflow obstruction is reversible.
Bronchodilators increase airway calibre by relaxing airway
smooth muscle.
The test consists of comparing results between the reference FVC
(FVC PRE) and the FVC POST performed after the
administration of the drug. Increasing value of 13-15% of FEV1,
respect to the basal value (FVC Pre) is considered as a reversible
condition.
Main parameters are the following:
DFEV1%pre Change of FEV1 as a percentage of test PRE
DFVC%pre Change of FVC as a percentage of test PRE
DPEF%pre Change of PEF as a percentage of test PRE
Some authors states that the above mentioned parameters are too
dependent from the FVC Pre, hence latest reference (ERS93, [A
comparison of six different ways of expressing the
bronchodilating response in asthma and COPD; reproducibility
and dependence of pre bronchodilator FEV1: E. Dompeling, C.P.
van Schayck et Al; ERJ 1992, 5, 975-981]) recommend the
following parameters:
DFEV1%pred Change of FVC as percentage of predicted value
DFEV1%poss Change of FEV1 as percentage of possible value
Methacholine and Histamine Bronchial provocation Tests
The most common indication for performing methacholine and
histamine bronchial challenges is to diagnose hyperresponsive
airways. Some patients demonstrate normal baseline pulmonary
function despite complaints of “tightness” wheezing, cough, and
a little or not response to bronchodilator. Other patients
demonstrate spirometric improvement after use of bronchodilator
have diurnal variation in peak flows. In this groups aerosolised
bronchial challenges are used to confirm a diagnosis of Asthma.
We can summarise the use of the test as follows:
1. Diagnose asthma
2. Confirm a diagnosis of asthma
88 - Pony FX User Manual
3. Document the severity of hyperresponsivness
4. Follow changes in hyperresponsivness
When patients with hyperresponsive airways inhale certain
pharmacologic agents (i.e. Methacholine or histamine) the
airways respond by constricting.
Test consists of executing repeated FVC following the
pharmacologic agents inhalation according to an established
protocol. The fall of the FEV1 parameter is used to calculate the
bronchial hyperresponsivness. The most important parameter is
the PD20 that is amount of drug (mg/ml) that causes a reduction
of 20% of the FEV1 respect the basal value (without drug).
Main parameters are:
P10 Dose that causes a 10% fall of FEV1.
P15 Dose that causes a 15% fall of FEV1.
P20 Dose that causes a 20% fall of FEV1.
The representative plot is the Dose/response curve, showing the
percentage variation of FEV1 versus the Drug dose in
logarithmic scale.
The program assumes as the baseline test the best FVC pre
carried out during the today’s visit. You can change the reference
pre test editing the Post test.
The name of the drug, its quantity and its unit of measurement,
can be typed immediately before any FVC post manoeuvre
(manual protocol) or can be stored in a database of
bronchoprovocation (File/Bronchial Provocation protocols
Database…).
Perform the test
(During 1st step only) select Protocol... from the Test menu and

Bronchial Provocation protocols Database
The response to a bronchoprovocator is usually assessed in terms
of change in the FEV1, vital capacity or airways resistance on the
basis of serial measurements (FVC manoeuvres) in which the
results of the initial test constitute the reference values. The
international literature proposes several standardised protocols in
order to address the methodological issues of the various
available techniques.
The possibility to store a bronchoprovocation protocol in a
database is useful to simplify and automate the sequence of
operations that the Physician need to execute during the
bronchoprovocation tests.
The typical sequence of activities to carry out a
bronchoprovocation test are:
1. Typing and storing a bronchoprovocation protocol in the
database (usually only once).
2. Selection of protocol among the list of the ones already
present in the database before carrying out the FVC post
tests (the selection of “manual protocol” allows to execute
the test fully manually).
3. Performing the Post tests.

System maintenance
All service operations which are not specified in this user manual
should be performed by qualified personnel in accordance with
the service handbook (to be required to the manufacturer).
All materials used in the construction of the Pony FX are non
toxic and pose no safety risk to the patient or operator.
Prior to the device cleaning, disinfection and inspection it is
necessary to switch off the device and to disconnect adapters
from the supply mains.
In order to guarantee the highest accuracy of measurements we
recommend you to disinfect the turbine periodically.
Cleaning and disinfection
Cleaning and disinfecting instructions are of fundamental
importance to control infections and assure patient safety. In fact
aspiration of residue, particles and contaminated agents are life –
threatening.
In this handbook we strongly recommend you to follow the rules
worked out by ATS and ERS (see: ”Lung Volume Equipment
and Infection Control” – ERS/ATS WORKSHOP REPORT
SERIES, European Respiratory Journal 1997; 10: 1928 – 1932),
which are summarised and adapted for COSMED products as
follows:
• Accessible internal as well as external surfaces of equipment
exposed to expired gas should be washed and disinfected
prior to testing of subsequent patients.
• Disinfecting should ideally be performed by heat
sterilisation, but gas or liquid sterilisation can be used if the
equipment is well cleaned first (no droplets of saliva/sputum
remain).
• Disposable gloves should be worn when handling
mouthpieces, when cleaning equipment exposed to saliva or
sputum and especially when drawing blood.
• Laboratory staff should wash hands prior to testing of each
patient.
• Adopt particular precautions when testing patients with
recognised high – risk communicable diseases (e.g.
tuberculosis, multidrug – resistant staphylococcus). In these
98 - Pony FX User Manual
cases, the clinical need for such testing should justify the
risks.
During the disinfection:
• do not use alcohol or other liquids containing gluteraldehyde
on the exterior surfaces of the equipment. Actually they can
damage polycarbonates plastics and may produce unhealthy
substances.
• do not use abrasive powders or glass cleaners containing
alcohol or ammonia on the plexiglas components of the
equipment
• do not steam autoclave any parts of the equipment unless it
is clearly specified.
• do not immerse the optoelectronic reader.
Warning: Do not
use alcoholic
solutions for the
turbine,
otherwise there
can be damages
to the plastic
material.
Cleaning the turbine flowmeter
It is necessary to disinfect periodically the turbine for sanitary
measures or/and for the correct device function.
As disinfecting solution it is suggested Sodium hypochlorite 5%
(bleach).
The disinfecting procedure is easy and may be effected every
time the user needs, keeping attention to some precautions:
1. Take out the turbine.
2. Dip it in a disinfectant solution (non alcoholic based) for
about 1 hour.
3. Rinse the turbine in a vessel, filled of clean water, shaking
gently to remove the disinfectant (do not clean the turbine by
putting it under running water!).
4. Let it dry to air.
5. After cleaning the turbine, check if the turbine propeller
rotates freely even with a low speed air flow.
6. Connect the turbine to the reader.
Precautions during the cleaning of the turbine
1. Do not expose the turbine to high heat and do not put it
under running water.
2. Do not ever dip the optoelectronic reader in any kind of
solution, the liquid infiltration would damage the internal
circuit.
3. Do not use alcoholic solutions to clean the turbine.

The equipment requires easy inspections to be carried out in
order to assure a proper electrical and mechanical safety level in
the years.
These inspections are highly recommended after a rough use of
the equipment or after a period of storage in unfavourable
environmental conditions.
Referring to the electrical safety, it is important to check the
conditions of insulation materials of cables, plugs and any other
visible part by means of simple inspection, when the equipment
is switched off and adapters (or electrical feeders) are
disconnected from the supply mains.
Extract the turbine from the unit and verify, by inspection, that
the turbine axis fits correctly its seats and the blade is strongly
fastened on the axis itself (it can be useful to shake slightly the
turbine in order to note any anomalous movement).
Check if there are any torn or broken components in the
breathing circuits: remember that they can create safety risk to
patients during tests.
