Preparing For Use

The contents of the Vitalograph micro package are:

• The spirometer device

• User Instructions

• Firmware Description

• SafeTway™ Mouthpiece samples

• Adaptor for fitting Precision Syringe or BVF

• Serial Spirometry Record Card samples

• Vitalograph micro – Serial Cable

• Vitalograph Print Utility (Windows PC application)

A 9-V (e.g.PP3) alkaline battery (not provided) must be installed before the
Vitalograph micro is used for the first time.

Open the door at the back of the unit to insert the battery. Make sure the
the battery.

Note that it is recommended to remove the battery if you do not intend
using the Vitalograph micro for several weeks.

Installing the Print Utility software on your PC

Once installed, the Vitalograph Print Utility automatically runs in the
background, printing to your PC or network printer or simply creating PDF
spirometry reports for you to file, transmit or archive in your PMS
software. You need not even be aware of it’s presence.

The Print Utility must be installed before the Vitalograph micro will print a
PDF document or a paper spirometry report on your PC’s printer. You must
be running Windows 2000 or XP Pro to use this utility.

Insert the CD into your CD drive, it should auto-run. Read and answer the
questions as they appear in the Install Shield. Think carefully about where
to send the PDF files on your computer. If you are trying out the Print

7

Utility for the first time you might like to point them to your desktop
initially.

Is is recommended to create the PDF files as an electronic archive. You
may also wish to set the ‘print’ setting, but note that the PDF files may be
printed at any time without using the ‘print’ setting.

Connecting the Serial Cable

If your PC has a Serial Port, simply plug the ‘D’ plug into the Serial socket.
Bring the jack plug end of the cable to the front of the PC ready to plug in
the Vitalograph micro after a test has been performed.

If you only have USB Ports (such as on a Laptop PC, you will need to buy
and install a USB to Serial converter, such as Vitalograph Cat No 77051.
Follow the install instructions on the CD.
IMPORTANT: If you use a USB/Serial converter, you will need to
change the setting of the Com Port in the Print Utility Application. Open
this by right clicking on the blue ‘V’ Icon at the bottom right-hand side of
your taskbar. If you do not know how to find which Com Port is being used
by the converter, seek help from your network administrator.

not the total volume that will be delivered. It is very important to
adjust this if you are using a syringe with a different stroke volume;
otherwise, the accuracy check will be incorrect.

Press . The display will look like …

6. Ensure the syringe piston is fully withdrawn. At this point, connect the
unit to the syringe and leave it in a stable position - do not move the
unit during this procedure.

7. With an even stroke, pump the air from the syringe through the device. The
stroke must be at least one second in duration.

8. Wait for a double beep, then withdraw the syringe piston fully and repeat this
procedure of injecting the full syringe volume until five beeps sound. It is very

important to wait for the double beep before withdrawing the piston each
time.

If there is a Thumbs Up on the LCD, then the
unit is within the +/- 3% accuracy tolerance1.

9. Turn the unit off by pressing . The device will automatically switch
of after 2 minutes.

1

The user will be prompted (by means of a double beep) for another stroke of the syringe when the volume

difference of the present stroke is not within 3% of the previous stroke. If the maximum of five strokes is
executed, then the five beeps will occur, signifying the end of the accuracy check. If there is a thumbs down icon
on the LCD, the unit is outside the 3% accuracy tolerance. Check for faulty assembly of the flowhead and your
accuracy check procedure. Recheck the accuracy. If still outside tolerance seek technical assistance.

Performing a Test

To obtain accurate and meaningful spirometry test results it is essential that
the operator is properly trained.
It is vital to conduct the test properly to ensure that there is proper use of
the device and interpretation of the test data during testing. There are many
types of training courses available. Please contact Vitalograph, your
distributor or your national lung association for more details.

Follow these steps to perform the FVC test.

1. Press . After several seconds, the display

like…

11

7. It is only possible to perform a test when the ‘blow icon’ is
displayed. Always watch for this to be displayed. It will be
accompanied by two beeps.

8. Fit a disposable SafeTway™™ mouthpiece (single use only). The use of a
nose-clip is also recommended. Give the following instructions to the
subject so that testing is performed properly.

a) Sit upright and fit the noseclip.
b) Hold the unit, keeping it away from your mouth. Do not jerk the unit

(this can de-stabilize the unit).

c) Inhale as deeply as possible, then insert the mouthpiece carefully into

your mouth, not like a trumpet, but clamping it gently between your

teeth.
d) Seal your lips round the mouthpiece.
e) Exhale as fast and as long as possible. Try to keep exhaling for at

least 6 seconds. (During exhalation the operator should encourage

the subject to keep going in an animated fashion. Keep eye contact

with the subject).

9. At the end of the blow the subject must remove the spirometer from
their mouth.

10. Wait for two beeps to indicate that the Vitalograph micro is ready for
the next blow. Repeat 3 times or more to ensure a good test.

Printing To The PC Utility

The PC Utility enables printing of a PDF file and/or to your PC Printer,
follow the steps below:

1) Immediately after a test session is completed, plug the jack plug into the
Vitalograph micro jack socket, which is located on the side of the
device.

2) Press  or  on the Vitalograph micro until the
following screen is displayed.

3) Press . The screen should immediately go blank. Put the unit down
carefully and talk to your test subject. The Vitalograph micro will take
about two minutes to download all the test data during which time it
should not be interfered with.

4) After two minutes transmission, the device will ‘beep’ and briefly
display ‘PRN’ again.

5) At this time the creation of the spirometry report begins in the PC Print
Utility.

6) Depending on your settings, a PDF will be created and/or a print
command will be sent to your designated printer2.

Note: The best test in the session is printed, not necessarily the last test
which is still showing on the LCD screen.

7) To cancel at any time press and hold the switch for 15 seconds
approx.

8) Another test can be performed as long as

is displayed.

2

If you installed the Print Utility with default settings, no print command will be sent but
a PDF file will be created in the following location:
C:\Program Files\Vitalograph\VitalPrint\Data

13

Figure 1 – Vitalograph Print Utility Product Perspective

Note: When the Vitalograph micro switches itself off, the best test from the
last session is retained until the next blow. This stored test may be printed at
any time as long as no new blow is detected by the device. Switch ON, press
Enter repeatedly until the Blow Icon and time are displayed, then press 
and  together to print.

Serial Spirometry Record

The subject’s session best test should be recorded on a Serial Spirometry
Record sheet to plot the FEV1 value against Lower Limit of Normality
(LLN). Pads can be ordered from Vitalograph (Cat. No. 63054).

Printing Directly To A Parallel Printer

If you have purchased the optional parallel printer/intelligent cable and
parallel printer, follow the steps below:

1) Ensure that the cable is correctly connected at both ends.

2) Press  or  until the following screen is displayed.

3) Make sure the printer is online and paper is installed.

4) Press

and walk away.

14

Note: Because of the serial data transmission, converted to parallel in the
cable, and the large amount of data, the printing speed is very slow using
this method of printing.

5) Only the best test in the session is printed. To cancel at any time press

and hold the switch for 15 seconds approx.

6) After the data is sent, the device displays PRN on screen again. Another

test can be performed as long as is displayed.

15

Care of the Vitalograph micro

Vitalograph recommends that you return this unit to your local service
centre for annual PPM servicing, which includes checks for function,
safety, performance, hygiene procedures, routine maintenance and
calibration certification.

Flowhead

It is recommended that the flowhead be removed for cleaning and
disinfecting at least monthly or every 50 tests. See below.

Hydrophilic Filters

You can see two small white cylindrical filters on the top of the unit after
the flowhead is removed. These are designed to prevent ingress of water
and should be replaced if they get accidentally immersed in water.
Otherwise, they are replaced once a year, as a part of the annual service.

SAFETY PRECAUTIONS

The Vitalograph micro does not offer protection against ingress of liquids
and must not be used in the presence of flammable agents.
The Vitalograph micro complies with EN60601-1-2: 1993 but does not
guarantee that other equipment in the vicinity will not be affected by
electromagnetic emissions from the Vitalograph micro. Similarly, other
equipment in the vicinity may affect the operation of the Vitalograph
micro.
It is recommended that all equipment used near the Vitalograph micro
complies with the relevant electromagnetic compatibility requirements for
that equipment and to check before use that no interference is evident or
disruptive. Increasing the distance between offending devices, and keeping
interconnecting leads as short as possible will help reduce the effect.

16

CLEANING AND DISINFECTING

General Recommendation

To reduce the risk of cross infection the use of SafeTway® mouthpieces is
recommended. A Risk Assessment should be carried out to assess the risks
presented to both operator and subject, and an action plan devised by the
facility to minimise the chance of cross infection occurring, particularly
where known-infectious or immuno-deficient subjects are being tested.

An assessment should be made of methods of decontamination available to
the operator, and their effectiveness against potential risks - a table of
materials used in the Vitalograph micro is provided below to assist in this.

It is recommended that in cases of high risk with no effective disinfection methods available, that the contaminated parts are disposed of. For this

device, the Flowhead Assembly: FLOWHEAD COMPLETE.

Routine Practice

A new mouthpiece (SafeTway mouthpiece) should be used for each
subject. A period of at least 5 minutes should be allowed between subjects
to allow settling of aerosolised particles.

It is recommended that the Flowhead Assembly be regularly cleaned
according to the guidelines of the user’s facility and replaced as a part of
the routine annual service.

In the event of visible contamination to the FLOWHEAD - it should be
cleaned and disinfected or replaced. It should also be replaced in the event
of damage.

All parts of the Vitalograph micro require cleaning, i.e. the removal of
visible particulate contamination. The parts of the Vitalograph micro that
make up the flowhead also require disinfecting.

Hygiene

It is vital for the user to set guidelines for protective hygiene measures
whilst performing spirometry testing. There are three main potential
sources of cross contamination, skin contact; aerosolised particles and
saliva/body fluids. By far the most important is the last item – a minimum
requirement is to use a new disposable mouthpiece for each subject tested.
We recommend using the SafeTway mouthpiece. We also recommend that
a period of at least 5 minutes be allowed between subjects. This allows
aerosolised organisms to be removed by gravitational sedimentation
between tests. (Am J Respir Crit Care Med Vol 159. pp 610-612, 1999)

17

Cleaning Instructions

All parts of the Vitalograph micro require regular cleaning, i.e. the removal of
visible particulate contamination. The parts of the Vitalograph micro that make up
the flowhead also require disinfecting. Vitalograph recommends that cleaning
and disinfecting should normally be carried out on a weekly basis. In addition to a
weekly cleaning and disinfection cycle, Vitalograph recommends cleaning and
disinfection of equipment to be carried out after use on infected subjects or prior to
use on immuno-compromised subjects. The user must determine what level of
disinfection is appropriate and acceptable in any particular circumstance.

Definitions of cleaning and disinfection are as defined in “Sterilization,
Disinfection and Cleaning of Medical Equipment: Guidance on
Decontamination from the Microbiology Committee to Department of
Health Medical Devices Directorate, 1996”

Recommendations for chemical disinfectants are derived from the PHLS
publication “Chemical Disinfection In Hospitals” 1993.

Disassembling for Cleaning and Disinfecting

1. Press in the two round ‘flowhead release buttons’.

2. Lift off the flowhead.

Clean the flowhead by washing in a mild detergent to remove

particulate contamination. To clean the Fleisch element, swill
vigorously in water with mild detergent. Do not attempt to “rub” or
“scrub” at capillaries. If the flow conditioning meshes appear dirty or
blocked the flowhead should be replaced.

Rinse with clean water.

Disinfect by immersion in sodium dichloroisocyanurate solution at 1000 ppm

concentration of free chlorine for 15 minutes. Prepare disinfectant solution as
directed in the manufacturer’s guidelines.

Rinse with hot water to aid drying.

Leave to dry completely before reassembling. Drying the Fleisch

element assembly may require placing it in a warm place overnight. A
drying cabinet is ideal, alternatively another heat source could be used.

Wiping with a 70% Isopropyl Alcohol impregnated cloth provides a suitable

form of cleaning and low-level disinfection for the case exterior, display,
screen, and keypad. Repeat at least weekly to prevent build-up of grime from
normal handling and use.

Always follow the safety guidelines given by the manufacturer of cleaning
and disinfectant chemicals or equipment.

19

Reassembling the Fleisch Flowhead

1. Ensure that the hydrophilic filters are undamaged and dry.

2. Orient the two circular holes under the flowhead with the hydrophilic filters

in the body.

3. Push the flowhead onto the body, making sure that the two buttons click

into place.

4. It is advisable to check accuracy and perform a functional check after

cleaning and disinfecting.
