Non-invasive blood pressure
14-13
Automatic NIBP double check
If the NIBP value exceeds the alarm limits, a low level alarm will be given and the auto
measurement takes place, if the alarm situation persists, the alarm will be raise to yellow level.
NIBP measurement limitations
•
A patient's vital signs may vary dramatically during the use of cardiovascular agents such
as those that raise or lower blood pressure or those that increase or decrease heart rate.
•
The NIBP feature not validated for pregnant, including pre-eclamptic patients use.
•
Although automated NIBP is generally safe and accurate, it has some limitations. It may
be difficult to obtain reliable readings under the following circumstances:
−
Shock accompanied by low blood pressure and pulse.
− Variations in blood pressure and pulse rate.
−
In patients with anatomic abnormalities, such as calcified (hardened) arteries or
subclavian compression.
− Compression of the cuff caused by shivering, seizures, arm movement, or bumping
against the cuff.
•
Proper sizing and position of the cuff are essential to obtaining reliable readings:
−
Too large a cuff is better than too small a cuff, which may yield falsely high readings.
− The cuff should also fit properly over the brachial artery (or whatever artery is being
used) so that the cuff is sufficiently sensitive to vibrations in the artery.
Checklist
Check that:
•
The hose is correct: grey NIBP hose for adults and pediatric and light blue for neonatal.
•
The O-ring on the hose connector is intact.
•
The connector is firmly pushed inside the cuff tube.
•
The NIBP hose is properly connected to the module and will not detach if pulled.
•
The NIBP cuff is correct for the patient size.
•
There are no holes or cracks in the cuff bladder or cuff tube.
•
The symbol indicating the center of the bladder is over the artery.
•
All residual air is squeezed out of the cuff before wrapping it around the arm.
•
The cuff is not loose.
•
The cuff is at heart level.
•
