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 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 4 Safety Summary Welch Allyn Spot Vital Signs LXi Temperature Warnings These warnings
