Welch Allyn 56 Propaq Encore Reference Guide
NIBP
Intended Use
The Propaq Encore noninvasive blood pressure channel (NIBP) indirectly measures arterial
pressures using an inflatable cuff. If ECG is also monitored, the Propaq Encore synchronizes
the NIBP measurement process to the occurrences of the R-wave, increasing accuracy in
cases of extreme artifact, diminished pulses, or some dysrhythmias.
The Propaq Encore NIBP channel has been calibrated to agree with a central invasive blood
pressure. Diastolic pressures may be 5 to 10 mmHg lower than the auscultatory equivalent.
Systolic pressures may be lower than radial invasive equivalent.
Neonatal Mode is intended for use on infants of up to about 44 weeks gestational age in
neonatal care settings. The Neonatal Mode provides the lowest cuff pressure and shortest
inflation time limits to ensure patient safety and comfort.
Pediatric Mode is intended to be used on larger infants and small children up to nine years
old in pediatric care settings. This mode supports the widest range of cuff sizes and a higher
range of patient numerics for the hypertensive infant or child while still restricting the cuff
pressure and inflation times to limits lower than those allowed for adults.
Adult Mode provides the full range of patient numerics and cuff pressures but limits the cuff
sizes available to the standard child cuff and larger.
Warning The patient's limb should be periodically observed to ensure that the
circulation is not impaired for a prolonged period of time.
The Propaq Encore should never be used to monitor NIBP on one patient
while simultaneously monitoring ECG on another patient.
If a noninvasive blood pressure measurement is suspect, repeat the
measurement. If you are still uncertain about the reading, use another method.
Do not attempt to take NIBP pressures on patients during cardiopulmonary
bypass.
Some or all NIBP safety functions are disabled in the NIBP TEST screen in the
Service Menu. Do not attempt to conduct NIBP TEST when the cuff is
attached to a patient.
