1.3. Contraindications
Do not measure NIBP on patients with sickle-cell disease or any condition
where skin damage has occurred or is expected.
Use clinical judgments to decide whether to perform frequent Auto NIBP
measurements on patients with severe thromboembolism disease because of the
risk of hematoma in the limb fitted with the cuff.
Use clinical judgments to decide whether to perform Auto BP measurement on
the patients of thrombasthemia.
NIBP measurements are impossible with heart rate extremes of less than
40bpm or greater than 240bpm, or if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible:
——with excessive and continuous patient movement such as shivering or
convulsions;
——if a regular arterial pressure pulse is hard to detect;
——with cardiac arrhythmias;
——with rapid blood pressure changes;
——with severe shock or hypothermia that reduces blood flow to the
peripheries;
——on a edematous extremity.
RESP monitoring and apnea alarm based on chest impedance method are not
suitable for patients with obstructive sleep apnea.
Patients with chronic septicemia or hypercoagulable state cannot consider
using this equipment. Because this equipment may cause suppurative or
non-irritating thrombus;
Patients with Parkinson's disease and tricuspid valve prolapse may be at risk
of arrhythmia.
