6 Introduction Welch Allyn Spot Vital Signs LXi
Blood Pressure Warnings
These warnings pertain to the Spot LXi blood pressure feature.
WARNING  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.
WARNING  To ensure pediatric blood pressure accuracy and safety, the Child 
Reusable Two-Piece Blood Pressure Cuff (4500-01), Infant Durable One-Piece 
Cuff (REUSE-07-2MQ), and the 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.
WARNING Avoid compression of the blood pressure hose or cuff tubing of Spot 
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 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.
