WARNING: As with all automatically infl atable 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 infl ation 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.
WARNING: Do not touch the monitor when a defi brillator is being discharged
(electrifi ed), as doing so may cause electric shock. NIBP monitoring only in
this monitor is protected against the discharge of a defi brillator. The other
functions (SPO2, TEMP) are not protected. Please be sure of no other patient
connections, except NIPB, before using the defi brillator.
Note:
A patient’s vital signs may vary 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.
7.1 General
NIBP processing by the monitor uses the oscillometric measuring technique. A motorized
pump in
fl
ates the cuff to initially block the
fl
ow 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 de
fl
ate,
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 pro
fi
le.
