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.
How ECG/RESP is displayed
Because of the critical nature of monitoring ECG, it is always displayed in the top part of
the waveform display area. The ECG waveform is the only waveform that cannot be
turned off using the Setup Wave Select Menu.
Respiration rate numerics are sourced from the CO
2
channel and displayed as BR when
CO
2
is active. Otherwise, respiration rate numerics are sourced from the ECG/RESP
channel and displayed as RR.
Patient artifact
Patient movement and other artifact might cause the waveform to move on the display.
Most artifact such as this is automatically detected, and the waveform is adjusted so that
it always remains centered in the waveform window.
Severe artifact and interference (such as interference from defibrillation) may cause the
waveform to move off the display. The Propaq Encore will always automatically reposition
the waveform in just a few seconds so you can see it again.
ECG/RESP menus and status window
ECG SIZE Selects the ECG waveform size; sizes are shown in millivolts per
centimeter (.2, .5, 1, 2, or 4 mV/cm) to the left of the waveform.
ECG LEAD Selects the ECG lead. The available leads are lead I, II, III, aVR, aVL,
aVF, or V. The Propaq's factory default lead setting is Lead II.
