12 General warnings and cautions Welch Allyn® Connex® ProBP™ 3400 digital blood pressure device
NIBP warnings and cautions
WARNING ProBP 3400 is not intended to measure blood pressure on neonatal
patients. The AAMI SP10:2002 standard defines neonates as children 28 days or
less of age if born at term (37 weeks gestation or more); otherwise up to 44
gestational weeks.
WARNING This device is not intended for use on neonates, infants, or children
under the age of 3 years. The effectiveness of this device has not been established
in pregnant, including pre-eclamptic, patients.
WARNING To ensure pediatric blood pressure accuracy and safety, the Small
Child Reusable Cuff (REUSE-08) is the smallest cuff approved for use with young
children.
WARNING Do not compress the blood pressure hose or cuff. This may cause
system errors or patient safety risks to occur.
WARNING NIBP readings may be inaccurate for patients experiencing moderate
to severe arrhythmia.
WARNING Inaccurate measurement risk. Do not use the device on patients who
are experiencing convulsions or tremors.
WARNING Use only blood pressure cuffs and hoses listed as approved
accessories to ensure safe and accurate NIBP measurements.
WARNING Patient injury risk. When several blood pressure measurements are
taken on the same patient, regularly check the cuff site and extremity for possible
ischemia, purpura, and/or neuropathy.
WARNING Do not allow a blood pressure cuff to remain on the patient more than
3 minutes when inflated above 15 mmHg. Excessive cuff tightness may cause
venous congestion, peripheral nerve injury, discoloration of the limb, and patient
distress.
WARNING Inaccurate measurement risk. Do not place the cuff where it can
disturb proper circulation. Do not place the cuff on any area where circulation is
compromised or on any extremity used for intravenous infusions.
WARNING The blood pressure cuff must be properly positioned to ensure blood
pressure accuracy and patient safety. Wrapping the cuff too loosely (preventing
proper inflation) may result in inaccurate NIBP readings.
13
WARNING Patient injury risk. Never install Luer Lock connectors on Welch Allyn
blood pressure tubing. Using these connectors on blood pressure cuff tubing
creates the risk of mistakenly connecting this tubing to a patient's intravenous line
and introducing air into the patient's circulatory system.
WARNING NIBP measurements may be inaccurate in the presence of excessive
motion artifact. Minimize extremity and cuff motion during blood pressure
readings.
WARNING The position and physiologic condition of the subject can affect a
blood pressure reading.
WARNING If the blood pressure cuff is not at heart level, note the difference in
reading due to the hydrostatic effect. Add the value of .2 kPa (1.80 mmHg) to the
displayed reading for every 2.5 cm (inch) above heart level. Subtract the value of .2
kPa (1.80 mmHg) from the displayed reading for every 2.5 cm (inch) below heart
level.
WARNING Proper blood pressure cuff size and placement is essential to the
accuracy of the blood pressure determination. See Blood pressure cuff selection
for sizing information.
WARNING Continuous cuff pressure due to connection tubing kinking may result
in blood flow interference and harmful injury may occur to the patient.
WARNING Frequent measurements can cause injury to the patient due to blood
flow interference.
WARNING Do not place the cuff over a wound as this can cause further injury.
WARNING Blood flow interference may result if the application of the cuff and its
pressurization on any limb where intravascular access or therapy, or an arterio-
venous (A-V) shunt is present and could result in injury to the patient.
WARNING Avoid pressurizing a cuff on the arm side of a mastectomy.
WARNING Pressurization of the cuff may result in temporary loss of function of
simultaneous used monitoring equipment applied on the same limb as the cuff.
WARNING The automated sphygmomanometer needs to be checked to ensure
that its operation does not result in prolonged impairment of blood circulation of
the patient.

Blood pressure hose and cuff
Identify and have available the ProBP 3400, blood pressure cuff, and the blood pressure hose.
1. Inspect the blood pressure hose; notice that one end has a single, gray Welch Allyn FlexiPort
fitting and the other end is plain with two recessed holes.
2. Completely push the plain end of the blood pressure hose onto the two silver blood pressure
ports on the device. Make sure the hose is fully seated.
3. Snap the Welch Allyn FlexiPort connector onto the blood pressure cuff.
Blood pressure cuff selection
Careful sizing of the cuff is important for accurate blood pressure readings. If the cuff is too small or
too large, you may have false high or low readings, respectively. When there is an area of overlap
for using a smaller or larger cuff, use the larger size cuff.
The device uses oscillometric technology to determine blood pressure; therefore, if the cuff
extends to the antecubital fossa (bend in the elbow), you can still acquire an accurate blood
pressure reading.
Measure the arm circumference (midway between the elbow and shoulder) for the correct cuff
size.
Wrap the cuff around the patient’s upper arm and verify that the artery index marker falls within the
two divisions that identify the “range” on the cuff to indicate a proper fit.
The following table provides measurements for Welch Allyn blood pressure cuffs.

Blood pressure procedure
Blood pressure measurement
WARNING Patient injury risk and inaccurate measurement risk. Do not place the
cuff where it can disturb proper circulation. Do not place the cuff on any area
where circulation is compromised or on any extremity used for intravenous
infusions.
WARNING Patient injury risk. The blood pressure cuff must be properly
positioned to ensure blood pressure accuracy and patient safety. Wrapping the
cuff too loosely (preventing proper inflation) may result in inaccurate NIBP
readings.
WARNING Patient injury risk. Do not allow a blood pressure cuff to remain on the
patient more than 3 minutes when inflated above 15 mmHg. Excessive cuff
tightness may cause venous congestion, peripheral nerve injury, discoloration of
the limb, and patient distress.
WARNING Patient injury risk. ProBP 3400 is not intended to measure blood
pressure on neonatal patients. The AAMI SP10:2002 standard defines neonates as
children 28 days or less of age if born at term (37 weeks gestation or more);
otherwise up to 44 gestational weeks.
WARNING Patient injury risk. This device is not intended for use on neonates,
infants, or children under the age of 3 years. The effectiveness of this device has
not been established in pregnant, including pre-eclamptic, patients.
The preferred blood pressure measurement site for adults and children is the upper arm. Keep the
patient’s arm relaxed and motion-free during measurement(s). The patient should be seated and
relaxed for 5 minutes prior to the blood pressure measurement. The patient should also be
comfortably seated, legs uncrossed, feet flat on the floor, back and arm supported. The middle of
the cuff should be at the level of the heart. The patient should not talk during the measurement.
35
Obtain blood pressure measurement
Patient position:
Recommended operator position:
1. Stand in front of the device within 1 meter.
2. Face the device with the monitor at an angle that allows you to easily view the screen.
To initiate blood pressure measurements:
1. Press the Power on/power off button to turn the device on.
2. Properly size the blood pressure cuff and position it around the patient's bare upper arm with
the artery index marker over the brachial artery. Leave room between the cuff and the arm for
no more than two fingers.
3. From the Home screen, press the Blood Pressure Start/Stop button.
The ProBP 3400 inflates the blood pressure cuff to the appropriate pressure and displays the
pressure as the blood pressure cuff is deflating.
If your device contains the SureBP feature (captures blood pressure on inflation): From the
Home screen, press the Blood Pressure Start/Stop button. The ProBP 3400 inflates the cuff to
the appropriate level, measuring the blood pressure as the cuff is inflating. The systolic display
shows the pressure in the cuff as the blood pressure determination is in process. If the device is
unable to determine a blood pressure while the cuff is inflating due to patient movement,
excessive noise, or an arrhythmia, the device will use the Step algorithm to inflate the cuff to a
higher pressure, then attempt to measure the blood pressure while deflating the cuff.
Pressing the Blood Pressure Start/Stop button at any time during a blood pressure determination
aborts the measurement and rapidly deflates the cuff.
When complete, the ProBP 3400 device displays systolic, diastolic, pulse rate measurements, and if
enabled, MAP calculation.

Troubleshooting
Inaccurate blood pressure readings
Possible cause Corrective action and explanation
Incorrect cuff size
Use Welch Allyn approved cuffs only.
Measure patient’s arm circumference midway
between elbow and shoulder (see “Blood pressure
cuff selection” to select correct cuff size).
Patient’s arm position Ensure patient’s arm is at heart level.
Arm movement during blood pressure cycle
Keep arm still during blood pressure cycle.
Movement may cause inaccuracies from artifact.
Blood pressure taken over clothing Take blood pressure on a bare arm.
Arrhythmia
Check for regularity of heart rate (palpate pulse or
check device).
Moderate to severe heart rate irregularities may make
blood pressure difficult to measure accurately.
Change in blood pressure between auscultatory
reading and ProBP 3400 reading
Check blood pressure immediately before ProBP 3400
reading.
Blood pressure is dynamic and changing. It is normal
for blood pressure to fluctuate 5 to 10 mmHg.
Incorrect reference Use the correct Korotkoff sound to determine diastolic
blood pressure.
• Many listeners incorrectly equate diastolic blood
pressure with the disappearance of sound only
(phase 5). ProBP 3400 was developed using the
American Heart Association recommendations,
which state that phase 5 be used unless sound
continues to 0 mmHg, in which case the change
in the quality of sound (phase 4) is to be used.
Deflate cuff no faster than 3 mmHg per second.
• One of the major sources of error in auscultatory
blood pressure measurement is deflating the cuff
65
Possible cause Corrective action and explanation
too quickly. The American Heart Association
recommends deflation no faster than 3 mmHg
per second.
Only use a sphygmomanometer that is calibrated.
• An uncalibrated sphygmomanometer may result
in inaccurate blood pressure measurements.
Poor auscultatory sound recognition by observer Use high-quality stethoscope. Have a different
observer check patient’s blood pressure.
