General warnings and cautions Welch Allyn Connex® ProBP™ 3400 digital blood pressure device

12

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 To ensure pediatric blood pressure accuracy and safety, the Small
Child Reusable Cuff (REUSE-08) and the Small Child Disposable Cuff (SOFT-08) are
the smallest cuffs approved for use with young children. The child's arm must fit
within the range markings on the cuff.

13

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.

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.

14

NIBP warnings and cautions Welch Allyn Connex® ProBP™ 3400 digital blood pressure device

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.

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.

23

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 measurement

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).

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.

37

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.

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 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.

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.

reading and ProBP 3400 reading

Incorrect reference Use the correct Korotkoff sound to determine diastolic

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).

Keep arm still during blood pressure cycle.

Movement may cause inaccuracies from artifact.

Check for regularity of heart rate (palpate pulse or
check device).

• 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
too quickly. The American Heart Association
