Blood Pressure Warnings
These warnings pertain to the Spot Vital Signs LXi blood pressure feature.
WARNING Spot Vital Signs 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.
WARNING To ensure pediatric blood pressure accuracy and safety, the Child
Reusable Two-Piece Blood Pressure Cuff (4500-01), Infant Durable One-Piece
Cuff (5082-82-4MQ), and the Infant Disposable One-Piece Cuff (5082-92-4MQ)
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.
WARNING Avoid compression of the blood pressure hose or cuff tubing of Spot
Vital Signs LXi. This may cause system errors to occur in the device.
WARNING Patients who are experiencing moderate to severe arrhythmias may
give inaccurate blood pressure measurements.
WARNING Spot Vital Signs LXi does not operate effectively on patients who are
experiencing convulsions or tremors.
WARNING Use only Welch Allyn blood pressure cuffs and/or hoses. Using other
manufacturers' blood pressure cuffs and/or hoses may produce inaccurate blood
pressure readings.
WARNING 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 10 minutes when inflated above 10 mmHg. This may cause patient distress,
disturb blood circulation, and contribute to injury of peripheral nerves.
WARNING Do not place the cuff on any extremity that is used for intravenous
infusions or any area where circulation is compromised.
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 Do not change the connector(s) on the blood pressure cuff tubing of
this device to luer type. Luer type connectors are commonly used in intravenous
infusion systems. Using the luer connectors on blood pressure cuff tubing
creates the risk that the blood pressure tubing could be mistakenly connected to
a patient's intravenous line, resulting in the introduction of air into the patient's
circulatory system.
