Spirometry is the most basic and frequently performed test of
pulmonary (lung) function. A device called a spirometer is used to
measure how much air the lungs can hold and how well the
respiratory system is able to move air into and out of the lungs.
Because spirometry is based on a maximal forced exhalation, the
accuracy of its results are highly dependent on your understanding,
cooperation, and best efforts; therefore good coaching is essential.
Spirometry differs from peak flow readings in that spirometry
records the entire forced breathing capacity against time, and peak
flow records the largest breathing flow that can be sustained for
10 milliseconds. Both are often used in asthma care.
Why would I need a spir
This test is used to deter
ule out any kind of obstr

restrictive disease that limits the expansion and capacity of the
lungs. Spirometry is most often used to diagnose and monitor lung
problems, such as chronic bronchitis, emphysema, pulmonary
osis, chronic obstructive pulmonary disease (COPD), or asthma.

Spirometry is also used to monitor how well medications for
respiratory problems are working and to evaluate breathing
capability prior to surgery.
How is spirometry performed?
A spirometry test is done with a spirometer, which consists of a
mouthpiece and disposable tubing connected to a machine that
records the results and displays them on a graph. To perform
spirometry, you must breathe through a flow transducer while
performing certain breathing maneuvers like deep inhalation or
forceful exhalation. Some of the test measurements are obtained

uctive disease that blocks breathing, or
tness of breath, to
by normal breathing, and other tests require rapid and forceful
inhalation and/or exhalation. The volume of air inhaled or
exhaled, and the length of time each breath takes are recorded
and analyzed.
Nose clips are usually used to make sure air is only coming out
of the mouth. Sometimes a test will be repeated to get the best
and maximum effort. Often, the tests are repeated after a person
takes a medication that opens the airways of the lungs (a bronchodilator). A spirometry test can take anywhere from 5 minutes
to a half an hour, depending on the different types of breathing
tests being performed.
Are there risks associated with spirometry?
The risks are minimal for most people. Because the test
involves forced and rapid breathing, some people may experience
temporary shortness of breath. Spirometry should not be done if a
person suffers from chest pains, has had a recent heart attack, or
has serious heart disease. There is a small risk of a collapsed lung
in people with a certain type of lung disease.
How should I pr
Do not eat a heavy meal before spirometry testing. Refrain from
smoking for 4 to 6 hours before the test. Empty your bladder right
before testing.

1 Install Software and USB Drivers
• This quick start guide is intended for use with CardioPerfect
orkstation Version 1.6.0 or higher.
W
or complete directions for use and warnings, please
• F
consult your user manual located on the SW CD.
2 Connect USB Dongle to CPU
• Use the USB extension cable supplied
with the sensor to lessen chance of
USB connector damage
• Connect the pressure tubing to the
sensor and the other end of the
tubing to a flow transducer.
• Connect the USB sensor to a USB port on
your computer.
3 Update Calibration Code
SPIROPERFECT
QUICK START GUIDE
Each lot of flow transducers has a specific Calibration code.
Make sure to update these in the SW when you receive a
new lot of flow transducers.
The Lot number and Calibration Code are located on the
outside packaging label of the flow transducer box. Update
this information in the pre-calibration window or in the
Recording tab of the spiro settings.
4 Calibrate the Spirometer
6 Patient Preparation
The spirometry module must be opened before you can perform
a calibration.
• Select Calibrate located on the Toolbar.
• Update Calibration Code if needed, and Temperature, Humidity
and Pressure fields.
• Press the Next button to continue.
• Pull syringe plunger out before connecting it to a new flow transducer.
• Press the Calibration button in the window.
• Wait until the message “Initializing sensor” disappears and the
dialogue box with the image of the syringe appears.
• Verify the syringe is completely filled and press the OK button.
• Push the plunger in and pull it out without stopping in between.
5 Select Patient
• Patient may sit or stand.
• Patient should loosen tight clothing.
• Patient should elevate chin and extend the neck slightly.
• Patient should use a nose clip or pinch his/her nostrils
with fingers.
Practice the procedure with the patient before starting the test
Verify that no finger is blocking the back of the flow transducer if
the patient holds it. This would create high back pressure and
result in extremely high % prediction, rendering the effort invalid.

• Close lips and teeth around the flow transducer to create a
tight seal, like if you were blowing in a musical instrument.
• Do not block the mouthpiece back screen with fingers.
• Keep your chin slightly elevated and make sure that your
tongue is out of the flow transducer.
• Take a good deep breath.
