NIBP Monitoring
WARNING: As with all automatically inflatable blood pressure devices, continual
cuff measurements can cause injury to the patient being monitored. Weigh the
advantages of frequent measurement and/or use of STAT mode against the risk of
injury.
WARNING: During use on patients, ensure that heavy objects are not placed on the
hose. Avoid crimping or undue bending, twisting, or entanglement of the hose.
WARNING: Never use an adult or pediatric monitor setting or cuff for an NIBP
measurement on a neonatal patient. Adult and pediatric inflation limits can be
excessive for neonatal patients, even if a neonatal cuff is used.
WARNING: NIBP readings may be inaccurate for patients experiencing moderate to
severe arrhythmia.
Note: A patient's vital signs may 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.
Note: Blood pressure measurements can be affected by the position of the patient, the
patient's physiological condition, and other factors.

General

NIBP processing by the monitor uses the oscillometric measuring technique. A motorized
pump inflates the cuff to initially blocking the flow of blood in the extremity. Then, under
monitor control, the pressure in the cuff is gradually reduced, while a pressure transducer
detects air pressure and transmits a signal to the NIBP circuitry.
When the cuff pressure is still above systolic pressure, small pulses or oscillations in the cuff
pressure begin to be sensed by the transducer. As the cuff continues to deflate, oscillation
amplitude increases to a maximum and then decreases. When maximum oscillation
amplitude occurs, the cuff pressure at that time is measured as mean arterial pressure
(MAP). The systolic and diastolic pressures are calculated based on analysis of the
oscillation amplitude profile.
