48 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor
Important information about automatic measurements
A blood pressure measurement will begin when the minute of the time of day clock is
evenly divisible by the interval. For example, if the interval is set to 10 (minutes),
measurements will begin at the hour and at 10, 20, 30, 40, and 50 minutes past the hour.
Note, however, that for intervals 1, 2, or 3 (minutes), measurements begin 1, 2, or 3
minutes after the interval is set. For example, if the 1 minute interval is selected at
10:45:20, the next measurement starts at 10:46:20.
The start time may be delayed if the previous measurement ended within 30 seconds of
the scheduled start time, because the monitor requires that the cuff pressure be below
5 mmHg for a minimum of 30 seconds between measurements to allow time to restore
blood flow to the limb.
NIBP messages
The following NIBP messages can appear in the equipment alert window. An NIBP
caution message also appears in the numerics window. If an error number (ERR# x) is
listed in an NIBP trend printout or display, it indicates that the corresponding NIBP
equipment alert occurred.
AIR LEAK, CHECK HOSE (ERR# 1). The Propaq Encore could not properly inflate cuff.
Check the hose and cuff for obvious leaks, such as O-rings in the hose connections.
CUFF NOT DETECTED (ERR# 2). During cuff inflation the detected pressure did not
sufficiently rise. Check that the cuff connection is tight and take the measurement
again.
KINKED HOSE, CHECK HOSE (ERR# 3). The Propaq Encore could not properly inflate
cuff. Check for a kinked hose between the monitor and the patient.
OVERPRESSURE CONDITION (ERR# 4). The pressure in the cuff exceeded the
acceptable limits for patient mode. Check the hose and try taking another
measurement.
WEAK PULSES, CAN'T FIND SYS/DIA (ERR# 5). There are not enough pulses to
determine the systolic or diastolic pressures, but a mean pressure is available. Try
reapplying the cuff after squeezing as much air from it as you can.
ARTIFACT, CAN’T FIND SYS/DIA (ERR# 6). The systolic or diastolic pressures are
unreliable due to artifact, but a mean pressure is available. May be caused by patient
motion.
NO PULSES DETECTED (ERR# 7). The cuff may not be properly applied to the patient,
or the patient may not have detectable pulses due to shock or arrhythmias.
CONNECT ECG TO REDUCE NIBP ARTIFACT (ERR# 8). NIBP artifact prevents a valid
reading. Connect ECG electrodes to improve NIBP measurements.
NO VALID BLOOD PRESSURE FOUND (ERR# 9). This message can occur due to
motion artifact, the Propaq Encore being set in the wrong patient mode, or the wrong
hose or cuff being used in relation to the patient mode.
WARNING The Propaq Encore cannot differentiate between physiologic and cuff
application causes of the NO PULSES DETECTED message. Always evaluate the
patient for presence of life threatening conditions whenever this message occurs.
