Aneroid Sphygmomanometer
Use, Care, & Maintenance

Device Description and Intended Use
An aneroid sphygmomanometer is used by professional healthcare providers and individu-
als trained in the auscultatory blood pressure technique to determine systolic and diastolic
blood pressure in humans.
Contraindications:
Aneroid sphygmomanometers are con-
traindicated for neonate use. Do not use with
neonatal cuffs or neonate patients. Review
the size chart (right) for proper age and limb
range usage.
General Warnings
A warning statement in this manual identifies a condition or practice which, if not cor-
rected or discontinued immediately could lead to patient injury, illness, or death.
WARNING:
Do not allow a blood pressure cuff to remain on patient for more than 10
minutes when inflated above 10 mmHg. This may cause patient distress, disturb blood
circulation, and contribute to the injury of peripheral nerves.
WARNING: If luer lock connectors are used in the construction of tubing, there is a
possibility that they might be inadvertently connected to intra-vascular fluid systems,
allowing air to be pumped into a blood vessel. Immediately consult a physician if this occurs.
WARNING: Safety and effectiveness with neonate cuff sizes 1 through 5 is not estab-
lished.
WARNING: If this equipment is modified, appropriate inspection and testing must be
conducted to ensure its continued safe use.
WARNING: Do not apply cuff to delicate or damaged skin. Check cuff site frequently
for irritation.
WARNING: Only use the cuff when the range markings indicated on the cuff show that
the proper cuff size is selected, otherwise erroneous readings may result.
WARNING: Allow space between patient and cuff. Two fingers should fit in this space
if the cuff is correctly positioned.
WARNING: Do not apply cuff to limbs used for IV infusion.
WARNING: Patient should remain still during measurement to avoid erroneous read-
ings.
WARNING: When using with an infant or child cuff, extra care must be taken to pre-

vent over-inflation. With smaller cuffs (infant or child) the cuff can inflate to over
300mmHg with just two full compressions of the bulb. To prevent discomfort or injury to
the patient and damage to the instrument, bulb should only be partially squeezed, so that
each “stroke” inflates the cuff in 40mmHg to 60mmHg increments until inflated to the de-
sired level.
WARNING: This product may contain a chemical known to the state of California to
cause cancer, birth defects, or other reproductive harm.
CAUTION:
To obtain the greatest accuracy from your blood pressure instrument, it is
recommended that the instrument be used within a temperature range of 50°F (10°C)
to 104°F (40°C), with a relative humidity range of 15%- 5% (non-condensing).
CAUTION: Extreme altitudes may affect blood pressure readings. Your device has been
designed for normal environmental conditions.
Operation of Pocket Aneroids
This booklet contains operating and main-
tenance information for pocket aneroid
sphygmomanometers. Please read and re-
tain.
Your pocket aneroid sphygmo-
manometer consists of an aneroid
manometer (gauge), complete inflation
system, (latex-free inflation bladder,
squeeze bulb, and the valve), a zip-
pered carrying case, and operating in-
structions.
Most models come preassembled and ready for use. If assembly is
required, attach gauge and bulb and valve assemblies to the tubes as shown in illustration.
To facilitate, use alcohol or soapy water.
Measurement Procedure
1. Patient P siti n
The patient should sit or lie comfortably. The arm should be fully supported on a flat sur-
face at heart level. (If the arm’s position varies, or is not level with the heart, measurement
values obtained will not be consistent with the patient’s true blood pressure.) When seated,
the patient should have their back and arm supported, and their legs should not be crossed.
The patient should relax prior to measurement comfortably for five (5) minutes and
should refrain from talking or moving during measurement. Observer should view manome-
ter in a direct line to avoid “Parallax error”.
2. Apply the cuff
Nylon cuffs are specially designed to promote the precisely accurate determination of blood

pressure. Index and range markings ensure use of
the correct cuff size. The artery mark indicates
proper cuff positioning.
Place the cuff over the bare upper arm with the ar-
tery mark positioned directly over the brachial ar-
tery. The bottom edge of the cuff should be
positioned approximately (1”) one inch (2-3cm)
above the antecubital fold. Wrap the end of the cuff not containing the bladder around the
arm snugly and smoothly and engage adhesive strips (Figure 1).
NOTE: If the unit is equipped with a calibrated
nylon cuff, featuring Index and Range markings, a
correct fit may be verified by checking that the
Index Line falls between the two Range Lines.
(Figure 2).
3. Inflate the cuff
Close the valve by turning thumbscrew clockwise.
Palpate the radial artery while inflating the cuff. Be sure to inflate cuff quickly by squeezing
bulb rapidly.
Inflate cuff 20-30 mmHg above the point at which the radial pulse disappears.
NOTE: Cuff pressure range is 0 mmHg to 300 mmHg.
4. P siti n the Steth sc pe
Position the chestpiece in the antecubital space below the cuff, distal to the brachium. Do
not place chestpiece underneath the cuff, as this impedes accurate measurement. Use the
bell side of a combination stethoscope for clearest detection of the low pitched Korotkoff
(pulse) sounds.
5. Deflate the cuff
Open the valve to deflate the cuff gradually at a rate of 2-3 mmHg per second.
6. Measurement
Record the onset of Korotkoff sounds as the systolic pressure, and the disappearance of
these sounds as diastolic pressure. (Some healthcare professionals recommend recording
diastolic 1 and diastolic 2. Diastolic one occurs at phase 4).
NOTE: It is recommended that K4 be used in children aged 3 to 12, and K5 should be used
for pregnant female patients unless sounds are audible with the cuff deflated, in which case
K4 should be used. K5 should be used for all other adult patients.
After measurement is completed, open valve fully to release any remaining air in the cuff.
Remove cuff.

Care and Maintenance
STORAGE:
P cket Gauge: After measurement, fully exhaust cuff then wrap cuff around gauge and
bulb and store in zippered carrying case.
NOTE: This product will maintain the safety and performance characteristics
specified at temperatures ranging from 50°F to 104°F (10°C to 40°C) at a relative
humidity level of 15% to 5%.
Man meter: Your pocket aneroid gauge requires minimal care and maintenance.
The manometer may be cleaned with a soft cloth but should not be dismantled under any cir-
cumstances.
Gauge accuracy can be checked visually; simply be certain
the needle rests within the printed oval when the unit is fully
deflated (Figure 3).
Should the indicator needle of the manometer rest outside of
this calibration mark, then the manometer must be re-cali-
brated to within ±3 mmHg when compared to a reference
device that has been certified to national or international
measurement standards. A manometer whose indicator needle is resting outside of this
mark, is NOT acceptable for use.
In the event that the gauge is ever in need of calibration, simply return for service. Damaged
or broken parts will be replaced as needed at a minimal charge. Refer to the warranty for spe-
cific details of warranty coverage.
The manufacturer recommends a calibration check every 2 years.
Cuff Cleaning and Disinfecting
NOTE: Use one or more of the following methods and allow to air dry:
Wipe with mild detergent and water solution (1:9 solution). Rinse.•
Wipe with Enzol per manufacturer’s instructions. Rinse.•
Wipe with .5% bleach and water solution. Rinse•
Wipe with 70% isopropyl alcohol.•
Launder with mild detergent in warm water, normal wash cycle. Remove bladder first.•
Cuff is compatible with 5 wash cycles.
Low Level Disinfection
Prepare Enzol enzymatic detergent according to the manufacturer’s instructions. Spray detergent
solution liberally onto cuff and use a sterile brush to agitate the detergent solution over entire
cuff surface for five minutes. Rinse continuously with distilled water for five minutes. To dis-
NOTE: Store gauge with
valve in full exhaust position.
