PROBLEM:
ECG waveform, heart rate corrupted by Electrosurgery or Electrocautery.
RECOMMENDED ACTIONS:
Monitor is specified to return to Clinical Utility within 8 seconds of discontinuance of electrosurgery;
Heart Rate display may require up to 20 seconds to stabilize.
Verify that electrosurgery neutral (return) line is making good contact with patient.
Route ECG cables as far as possible from electrosurgery site and neutral line.
PROBLEM:
ECG Heart Rate significantly differs from SpO
RECOMMENDED ACTIONS:
ECG heart rate may be inaccurate due to arrhythmia, cabling problems.
SpO2 pulse rate may be inaccurate due to poor perfusion, poor blood flow to limb, light interfering with
sensor, patient movement.
Manually measure pulse by
troubleshoot that instrument further.
PROBLEM:
Pacemaker signals not visible on ECG trace.
RECOMMENDED ACTIONS:
Pacemaker signals are displayed as captured; the Atlas Monitor does not have an option to present
symbolic indication of pacemaker signals;
Change ECG Bandwidth to Extended in Advanced Configuration menu.
Change ECG Gain to Automatic in Advanced Configuration menu.
PROBLEM:
Heart Rate inaccurate on pacemaker patient.
RECOMMENDED ACTIONS:
Certain unusual artifacts of pacemaker signals may be counted as pulse signals. Connect SpO
monitor displayed Pulse rate as an adjunct measurement.
In patients with pacemakers that are not successfully capturing the pulse, certain timing interactions
between pace signal and pulse can cause an occasional additional pulse beat to be counted.
E.1.5 Impedance Respiration
PROBLEM:
Cannot detect impedance respiration.
RECOMMENDED ACTIONS:
Move leads to mid-axillary positions as shown in Connecting the ECG Electrodes.
Check connections:
ECG trunk cable at Atlas Monitor socket.
ECG leads at trunk cable.
ECG leads at electrodes.
