NIBP Safety Information
NIBP Safety Information
The monitor cannot operate effectively on patients who are experiencing convulsions or tremors.
Warning
If the NIBP measurement is unsuccessful or when there are doubts about measurement values, assess
the patient's condition immediately. The patient's condition may have deteriorated to the point where
measurement limits are exceeded. If values appear questionable, it is the clinician's responsibility to
repeat the measurements.
Inaccurate measurements can be caused by:
•
Incorrect cuff applications or use, such as placing the cuff too loosely on the patient, using the
incorrect cuff size, not placing the cuff at the same level as the heart, or placing the cuff over
thick clothing or a rolled up sleeve
•
A leak in the cuff or tubing
•
Excessive patient motion, including CPR and bed movement
•
Serious episodes of shock, hypotension, or decreased body temperature
•
Frequent episodes of arrhythmia
The monitor displays results of the last blood pressure measurement until another measurement is
completed. If a patient's condition changes during the time interval between measurements, the
monitor does not detect the change or indicate an alarm condition.
Sometimes, electrical signals at the heart do not produce a peripheral pulse. If a patient's beat-to-beat
pulse amplitude varies significantly (for example, pulsus alternans, atrial fibrillation, rapid-cycling
artificial ventilator), blood pressure and pulse rate readings can be erratic and an alternate measuring
method should be used for confirmation.
A patient's vital signs can vary dramatically during administration of agents affecting the
cardiovascular system, such as those used to raise or lower blood pressure or raise or lower heart rate.
Ensure that heavy objects are not placed on the tubing. Avoid crimping or excessive bending, twisting,
or entangling the tubes.
Connecting the NIBP Cuff and Hose
Warning—Use only recommended Philips blood pressure tubing and cuffs. Using other cuffs or
tubing can result in inaccuracies.
Connect the appropriate hose to the cuff hose connector on the back of the unit. See Chapter2, Setting Up
the Monitor
Select the appropriate sized NIBP cuff and attach it to the hose. Sizes range from neonatal through large
adult and thigh.
Smart Inflation Feature
The VS1 monitor provides a Smart Inflation feature that inflates the cuff to a level based on a patient's
individual requirements. The monitor automatically inflates the cuff to a pressure above arterial occlusion.
Most monitors inflate to 180 mmHg (
be uncomfortable. The Smart Inflation feature monitors blood pressure during inflation, and stops inflating
when necessary, not at a preset pressure.
