32 Monitoring Welch Allyn Propaq CS Vital Signs Monitor
Take a Noninvasive Blood-Pressure (NIBP) reading
At powerup, the Propaq CS monitor has an NIBP default inflation pressure (cuff inflation
target) based on the patient mode (see
“NIBP specifications” on page 99 for the values).
After each NIBP measurement, the monitor adjusts the target inflation pressure to
optimize the next NIBP measurement. To avoid possible patient discomfort, turn the
monitor off and then on between different patients to reset the cuff inflation target to the
default value.
NIBP measurements can be adversely affected by poorly fitting cuffs or improper cuff
placement. Be sure to select the appropriate cuff and apply the cuff properly according to
the directions in this manual.
Improve NIBP accuracy with Smartcuf ™
NIBP measurements can be adversely affected by many factors such as cardiac
arrhythmias, sudden changes in blood pressure, body motions such as convulsions or
shivering, bumping the cuff, vibration, vehicle motion, or weak pulses.
The patented Smartcuf software filtering technology greatly increases NIBP
measurement accuracy in the presence of motion artifact or diminished pulses. Smartcuf
synchronizes the NIBP reading with the R-wave of the patient’s ECG to eliminate noise
created by external stimuli such as patient motion or vibration. The monitor must perform
ECG monitoring while using Smartcuf.
WARNING Periodically observe the patient’s limb to make sure that the
circulation is not impaired for a prolonged period of time. Also make sure the cuff
is properly placed according to the following instructions. Prolonged impairment
of circulation or improper cuff placement can cause bruising.
WARNING The Propaq CS monitor should never be used to monitor NIBP on
one patient while simultaneously monitoring ECG on another patient.
WARNING If a noninvasive blood pressure measurement is suspect, repeat the
measurement. If you are still uncertain about the reading, use another method.
WARNING Do not attempt to take NIBP pressures on patients during
cardiopulmonary bypass.
WARNING When monitoring NIBP, match the monitor patient mode to the NIBP
cuff. For neonates, set the monitor to Neonatal Mode unless the circumference of
the limb is too large for the cuff. In that case, use the Pediatric Mode. Be aware,
however, that the maximum cuff inflation limits are based on the patient mode,
not the cuff; the maximum cuff inflation limits for Pediatric Mode are greater than
for Neonate Mode (see
“NIBP specifications” on page 99 for values).
WARNING Before you use a Propaq CS monitor on a new patient, always turn it
off for a few seconds, then turn it on again. This clears the prior patient’s NIBP
cuff inflation target, trend values, and alarm limit settings.
Note NIBP measurements are affected by normal physiological pressure variations
from reading to reading.
