Blood Pressure Operation
Welch Allyn Spot Vital Signs LXi
Infant Disposable One-Piece Cuff (SOFT-07-2MQ) are the smallest cuffs approved for use
with young children and infants. The child’s arm must fit within the range markings on the
cuff.
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). Alternate blood
pressure measurement sites include the thigh, ankle, or forearm.
To initiate blood pressure measurements:
1.
Properly size the blood pressure cuff and position it around the patient’s bare upper
arm (or alternate site as necessary) with the artery index marker over the brachial
artery. Leave room between the cuff and the arm for two fingers.
2.
Press the Blood Pressure Start/Stop button. Spot LXi 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.
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, Spot LXi displays the systolic, diastolic, and pulse rate
measurements. If you have enabled MAP in the Internal Configuration Mode Spot LXi
also displays this value.
If Spot LXi is unable to determine a blood pressure while the cuff is inflating due to
patient movement, excessive noise, or an arrhythmia, the device will attempt to
measure the blood pressure while deflating the cuff.
WARNING Do not place the cuff on any extremity that is used for intravenous
infusions, or any area where circulation is compromised.
WARNING Using the same arm for cuff inflation and SpO
2
measurement may
cause inaccurate SpO
2
results.
WARNING Excessive cuff tightness may cause venous congestion and
discoloration of the limb.
WARNING Wrapping the cuff too loosely (preventing proper inflation) may result
in errors.
WARNING The Spot LXi 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.
Note
Spot LXi displays the pulse rate, as determined from the blood pressure
measurement method only if the SpO
2
option is absent or disabled. If the SpO
2
function is operational, all pulse rate determinations are a result of the SpO
2
measurement method.
