Introduction

Congratulations on your purchase of the new Labtron Model

240. This aneroid sphygmomanometer is both easy-to-use
and ideally suited for daily measurements. The systolic blood
pressure reading and diastolic blood pressure reading are
clearly shown at the completion of each reading.

Blood pressure measurements determined with your 240 are
equivalent to those obtained by a trained observer using cuff/
stethoscope auscultation method, within the limits prescribed by
the Association for the Advancement of Medical Instrumentation
(AAMI) SP 9 requirements.

Please read this manual carefully before use. For specific
information on your own blood pressure, contact your physician.
Please be sure to keep this manual.

About Blood Pressure

What is Blood Pressure?

Blood pressure is the pressure exerted on the artery tube while
blood flows through the arteries. The pressure measured when
the heart contracts and sends blood out of the heart is systolic
(highest) blood pressure. The pressure measured when the
heart dilates with blood flowing back into the heart is called
diastolic (lowest) blood pressure.

Why Measure Your Blood Pressure?

Among the various health problems afflicting people today,
problems associated with high blood pressure are by far
the most common. High blood pressure's dangerously strong
correlation with cardiovascular disease has made measuring
blood pressure a necessity for identifying those at risk.

Blood Pressure Standard:

The World Health Organization (WHO) and National High
Blood Pressure Education Program Coordinating Committee
have developed a blood pressure standard, according to which
areas of low- and high-risk blood pressure are identified. This
standard, however, is a general guideline, and blood pressures
vary between different people, age groups, etc.

About Blood Pressure

It is important that
you consult with your
physician regularly.
Your physician will
tell you your normal
blood pressure range
as well as the point
at which you will be
considered at risk.

Assembling the Unit

Lay out the parts as pictured below. The cuff should already be
folded. If the cuff is not pre-folded, lay the cuff flat in front of
you and fold the cuff so that the hook and pile material faces the
outside of the cuff loop.

1. Attach the gauge to the
tubing on the left.

2. Attach the double end
of the Y-tubing to the
binaural.

Helpful Tips

BEFORE

1. READ this instruction manual carefully.

2. MEASURE your blood pressure at the same time each day.

3. RELAX for at least 5 minutes before taking a measurement.

4. REMOVE tight fitting clothing from your left upper arm.

5. DO NOT eat, smoke or exercise for at least 30 minutes before
taking a measurement.

6. DO NOT talk or move during a measurement.

7. DO NOT take a measurement when you feel stressed.

DURING

1. APPLY CUFF at the heart level.

2. INFLATE unit to proper level.

3. DEFLATE unit at 2-3 mmHg per second.

4. RECORD your measurements.

5. SMILE. You’re helping your doctor and yourself.

AFTER

1. WAIT 5 to 10 minutes before taking another measurement.

2. CONSULT your doctor.

Correct Measuring Posture

A. Place your elbow on a table

so that the cuff is at the same
level as your heart.

Note: The level of your heart is slightly
below your armpit.

Relax your entire body, especially

the area between your elbow
and fingers.

B. If the cuff is not at the same

level as your heart or if you can
not keep your arm completely
still throughout the reading,
use a soft object such as a
folded towel to support your
arm.

C. Turn your palm upward.

D. Sit upright in a chair, and take

5-6 deep breaths.

Note: Avoid leaning back or crossing
your legs while the measurement is
being taken.

Applying the Cuff

To apply the cuff

1. Press two fingers one inch above the bend of the elbow on
the inside of the arm. You may feel the pulse of the brachial
artery. Even if you do not feel the pulse, the stethoscope will
allow you to hear the pulse sounds.

2. Slip cuff up your arm. Place the bottom edge of the cuff
approximately one-half inch above the elbow. Adjust the cuff
so that the stethoscope chestpiece sits on the inside of the
arm over the brachial artery.

3. Remove any clothing that restricts your upper left arm. Wrap
the cuff around your upper left arm. The rubber tubes should
point in the direction of your hand. Position the artery mark
over the main artery (on the inside of your arm) in the upper
arm.

Measurement Procedures

1. To fasten the cuff, press the hook material
firmly against the fuzzy pile material. Make
sure the stethoscope chestpiece sits over
the brachial artery. If necessary, readjust the
cuff.

2. Place your arm on a table so that the cuff is at
the same level as your heart.

CAUTION: Before you put the stethoscope binaural in
your ears, make sure the eartips are securely fastened to
the binaural.

3. Insert eartips into your ears. Adjust the metal
binaural for comfort.

4. Clip the gauge to a hard cover book on the table
in front of you. Hold the inflation bulb in your
right hand. Close the air release valve attached
to the inflation bulb by turning it clockwise.

5. To inflate the cuff, slowly and steadily pump the
inflation bulb.

Caution: Do not inflate the cuff above 280 mmHg. You may damage the
instrument or injure yourself. If you are unsure, consult your doctor for the
correct inflation level.

Note: If you KNOW your SYSTOLIC reading, pump the inflation bulb until
the gauge reaches approximately 50 mmHg ABOVE your average SYSTOLIC
reading. If you DO NOT KNOW your SYSTOLIC reading, pump the inflation
bulb until the gauge needle reaches 180 mmHg.

6. Slowly open the air release valve by turning it counter-clockwise.
Release the air at a rate of 2-3 mmHg per second.

Measurement Procedures

7. As the cuff deflates, listen carefully with
the stethoscope for your pulse beat.
The first sound represents the Systolic
reading and the last sound represents
your Diastolic reading.

NOTE: If you make a mistake do not reinflate the cuff. Release all the air.
Wait 1 minute. Start again. Waiting allows the engorged blood vessels
to return to normal. If you want to take successive readings, wait 5-10
minutes. Waiting allows the engorged blood vessels to return to normal.
You may require more rest time between measurements depending on
your health.

Care And Maintenance

To protect your unit from damage, please AVOID washing or
moistening the cuff or dropping the gauge.

When the cuff is fully deflated, the gauge needle stays within the
zero box. If the needle points outside of the zero box, the gauge
gives inaccurate readings.

Your new blood pressure unit has been carefully checked
to assure reliability and accuracy prior to shipment and use.
However, as with any sensitive instrument subjected to repeated
use, we recommend that your blood pressure gauge be checked
yearly by a medical professional for proper calibration.
