Blood Pressure Measurement Using
Diagnostic Desk System
Blood pressure measurements determined with this device are
equivalent to those obtained by a trained observer using the
auscultatory method, within the limits prescribed by the
American National Standard ANSI/AAMI SP10:, 2002,Manual,
electronic, or automated sphygmomanometers.
Intended Use
Welch Allyn aneroid sphygmomanometers are used by
professional healthcare providers and individuals trained in
auscultatory blood pressure technique to determine systolic and
diastolic blood pressure in humans and animals.
Contraindications
Welch Allyn aneroid sphygmomanometers are contraindicated
for neonatal use. Do not use with neonatal cuffs or on neonate
patients.
WARNINGS
A warning statement in this manual identifies a condition or
practice which, if not corrected or discontinued immediately
could lead to patient injury, illness, or death.
WARNING: If luer lock connectors are used
in the construction of tubing, there is a
possibility that they might be inadvertently
connected to intravascular fluid systems,
allowing air to be pumped into a blood
vessel. Immediately consult a physician if
this occurs.
WARNING: Do not allow a blood pressure
cuff to remain on the patient for more than
10 minutes when inflated above 10 mm Hg.
This may cause patient distress, disturb
blood circulation, and contribute to the
injury of peripheral nerves.
WARNING: Safety and effectiveness with
neonate cuffs (sizes from neo 1 to neo 5) is
not established.
WARNING: Use only Welch Allyn
manufactured blood pressure cuffs and
accessories; substitution might result in
measurement error.
WARNING: If the blood pressure
measurement device was used and stored
beyond the specific the scope of
temperature and humidity, the performance
may not be achieved.
Connection
1.
Connect one end of the coil tubing to the sphygmomanometer
valve at the bottom of the unit.
2.
Align and press the FlexiPortadapter onto the cuff port.
3.
Attach the inflation bulb to the tube (if needed).Use alcohol to
facilitate this.
4.
Join the coil tubing to the cuff tube.
5.
Verify an airtight seal is achieved at all connection points.
Operation
Blood pressure measurements can be affected by the position of the
patient and their physiological condition. Before beginning a procedure,
ensure that the patient rests for at least five minutes, has support for
their back and feet, and does not cross their legs. Passively support the
patient's lower arm and keep the upper arm at heart level. The
procedure needs to take place in a quiet environment with no talking.
Failure to follow these recommendations can result in inaccurate blood
pressure measurements.
1.
Select cuff size appropriate for the patient's arm circumference.
The applicable range, in centimeters, is printed on each cuff.
Note: The "Artery Index Marker" on the cuff should fall within the
"Range" indicated on the cuff. If the artery index marker falls short of the
indicated range, use a larger cuff to ensure accurate results. If the
artery index marker is past the range, use a smaller cuff to ensure
accurate results.
2.
Wrap the cuff around the arm with the artery index marker
located over the brachial artery and with the lower edge of the
cuff 2.5 cm above the bend in the elbow.
3.
Inflate cuff rapidly to a level 30 mm Hg above estimated (or
palpatory) systolic pressure.
4.
Partially open the valve to allow deflation at a rate of 2 to 3 mm
Hg per second. As the pressure falls, note systolic pressure and
diastolic pressure using your stethoscope
5.
Rapidly release the remaining pressure and record
measurements immediately. After a minimum of 30 seconds,
repeat the above steps for a second reading.
Specifications
The aneroid sphygmomanometer is accurate to ± 3 mm Hg. This
product will maintain the safety and performance characteristics
specified at temperatures ranging from 10 °C to 40 °C at a relative
humidity level from15% to 95%.
