ECG/RESP
Welch Allyn 44 Propaq Encore Reference Guide
6. If an electrosurgical unit is going to be used, place the ECG cable and electrode wires
as far as possible from the surgical site and from the electrosurgical return electrode
and its cables. This will minimize interference.
By now there should be some kind of ECG waveform displayed on the monitor. A
heart rate should be displayed to the right of the waveform. Depending on how the
Propaq Encore is programmed, a beep tone may occur with each detected QRS event.
7. If there is no waveform, check the electrodes, wires, cable, and the monitor for a
possible lead fault.
If an ECG electrode becomes disconnected or disrupted so that the Propaq Encore
cannot receive the ECG signal, a message and tone are conveyed with an equipment
alert.
Setting Up the ECG/RESP Channel
Press ECG or ECG/RESP (available with the Impedance Pneumography Option) to set the
selections:
ECG SIZE, ECG LEAD, RESP SZE (available with Impedance Pneumography). The MORE
button displays the second ECG/RESP menu and a status window with selections for HR/
PR TONE, PACER DISPLAY, ECG BANDWIDTH, and RESP LEAD (available with
Impedance Pneumography). If the patient being monitored has a pacemaker, you may want
to turn on the Pacer indicator function.
Setting ECG/RESP Alarms
Set the alarm limits according to your hospital's standards.
Motion artifact or other factors can cause false HR/PR alarms. To help minimize false alarms,
the Propaq delays or “holds off” triggering an HR/PR alarm for 3 seconds. During this
holdoff period, if the Propaq detects that the patient’s HR/PR vital sign has returned to
acceptable limits, the Propaq cancels the alarm holdoff. The next time an HR/PR limit is
violated, the Propaq starts a new 3-second HR/PR alarm holdoff period.
Two RESP leads are available. Choose the one that gives you the best signal.
If neither signal is adequate, it may be necessary to experiment with
nonstandard electrode placement such as placing the RA and LA electrodes
on the respective mid-axillary lines just above the level of the nipples.
