3. Insert lower pole into pole base.  
4. Assemble M8 screw, small washer, and large washer  
as shown on previous page. Install from the bottom  
9
through base into pole base. Use /16" wrench to tighten.  
5. Insert spring into lower pole.  
6. Insert upper pole into lower pole.  
7. Install height adjustment knob in upper pole. Adjust  
upper pole to desired height. Turn knob clockwise to  
tighten.  
8. Install basket on upper pole; insert two M4 screws to  
secure it as shown on previous page. Use Phillips screw-  
driver to tighten screws.  
9. Install lower bracket on upper pole; insert two M6  
screws and washers to secure it as shown on previous  
page. Use Phillips screwdriver to tighten screws.  
10. Slide sphygmomanometer's upper bracket into lower  
bracket.  
Ensure that sphygmomanometer is assembled as de-  
scribed, and that all components are securely fastened,  
before use.  
Adjust height: Turn the height adjustment knob counter-  
clockwise to loosen it, move upper pole to desired height,  
then turn knob clockwise to tighten.  
BLOOD PRESSURE  
Blood Pressure is a measure of the blood’s pressure in  
the circulatory system, which changes constantly during  
the course of the cardiac cycle. Blood pressure readings  
report two values. The higher reading (systolic pressure)  
shows the highest pressure in the arteries occurring when  
the heart contracts. The lower reading (diastolic pressure)  
shows the lowest pressure in the arteries, which occurs  
right before the heart contracts. Blood pressure readings  
Labtron 223B / V223 Mobile Adjustable Aneroid Sphygmomanometer  
 
 
are written with the highest value first, then the lowest  
value. Readings of 120/80 are considered to be normal,  
with high blood pressure being defined as a systolic  
pressure which is 140mmHg or more at rest and a diastolic  
pressure which is 90mmHg or more at rest. Only a patient’s  
physician is qualified to determine whether the readings  
obtained are normal for that person.  
Measuring blood pressure: Have the patient, while relaxed  
and in a sitting position, extend the arm from which the  
blood pressure will be taken to the front or laterally with  
the palm of the hand up.  
Attach the cuff and diaphragm: Hold the end of the cuff  
containing the inflation bag firmly against the inside of the  
bare upper arm with the artery symbol positioned over the  
brachial artery. Never place the cuff over clothing. Pull  
the opposite end of the cuff snugly around the arm and  
secure the Velcro® strips. The range lines, indicated by the  
arrows, show the correct cuff size when the cuff is placed  
on the arm. If the index line on the end of the cuff falls be-  
tween the two range lines, the cuff is the proper size. If the  
index line falls outside the range lines, a larger or smaller  
cuff should be used. The cuff should be snug, but not too  
tight. If one or two fingers can fit between the cuff and the  
arm, the cuff is properly secured. Place the diaphragm of  
the stethoscope over the brachial artery inferior to the  
cuff.  
Inflating the cuff: Close the bulb’s air valve by turning the  
air release valve clockwise. Squeeze the inflation bulb at a  
steady rate until the gauge’s needle points at approximate-  
ly 30mmHg above the individual’s normal systolic pres-  
sure value. If the individual’s normal blood pressure is not  
known, it is recommended to inflate to 200mmHg.  
Systolic blood pressure reading: Open the air release  
valve slowly by turning it counter-clockwise while holding  
the diaphragm of the stethoscope over the brachial artery.

Proper deflation rate is vital for an accurate reading. The  
recommended deflation rate is 2-3mmHg per second, or  
a drop of one to two marks on the pressure gauge with  
each heartbeat. Do not keep the cuff inflated any longer  
than necessary. As the cuff begins to deflate, listen care-  
fully with the stethoscope. Note the reading on the gauge  
as soon as a faint, rhythmic tapping or thumping sound is  
heard. The first sound is the systolic pressure reading. Al-  
ways check with your health care provider to ensure read-  
ings are performed correctly.  
Diastolic blood pressure reading: Allow the pressure to  
continue dropping at the same deflation rate. Note the  
reading on the gauge when the last audible thumping,  
swishing, or blowing sound is heard; this is the diastolic  
blood pressure reading. After a few seconds have passed  
and no audible thumping, swishing, or blowing sounds are  
heard, deflate the cuff using the air release valve complete-  
ly. Remove the cuff and stethoscope from the arm.  
Record the systolic and diastolic readings. Repeat the  
measurement two or more times to ensure accuracy. Only  
a patient’s physician is qualified to analyze blood pressure.

MAINTENANCE  
Recommended care and maintenance:  
Do not drop or pull excessively on the sphygmomanometer components.  
Never inflate beyond 300mmHg.  
Do not expose the cuff to direct sunlight.  
Do not put the sphygmomanometer in contact with sharp objects which could  
pierce the material and cause damage.  
Do not dismantle or disassemble sphygmomanometer component.  
Cleaning  
Wipe off the manometer, bulb, poles, basket and base with a  
clean, damp cloth. Wash the cuff with soap and cold water,  
rinse and air dry. Do not press cuff with a hot iron.  
Sterilization  
Do not use steam, heat or liquid disinfectants to sterilize the  
cuff, inflation system or manometer. Gas sterilization may be  
used on the cuff only, if necessary.  
Storage  
Always deflate the cuff completely before storage.
