• Make sure that leadwires are properly fastened and in good
condition.
• If these actions fail to resolve the problem, select a different lead.
Lead Fault Indication
The lead fault indication messages listed here are on the central
monitor/station and not the transmitter display.
The message CHECK XX (where XX identifies the failed or missing
electrode) appears in the ECG waveform zone if a lead fault occurs.
If automatic lead switching is enabled, another lead is automatically
selected so that monitoring is uninterrupted.
A LEADS OFF message appears if automatic lead switching is
disabled.
Noise Detection
A NOISY SIGNAL message appears in the ECG waveform zone of the
central monitor/station if noise is detected. If both the first and
second lead are noisy, the module suspends processing temporarily.
If the noise persists for 10 seconds, the system initiates an alarm. The
message and alarm cease when the noise disappears.
Notes:
• If monitoring is interrupted because of overload or saturation
of the input amplifiers, including overload caused by a
defibrillator discharge, the ECG waveform is shown as an
out-of-range signal accompanied by a NOISY SIGNAL or
HR UNAVAILABLE message.
• If the waveform shown does not appear noisy, but the NOISY
SIGNAL message persists, check all leads for noise before
calling a qualified field service engineer.
False Alarms
Careful attention to skin preparation and electrode application,
especially during setup, will reduce false alarms.
If false alarms occur, check for the issues from the list that follows:
• Excessive noise on the signal (the most common cause of false
alarms). Electrodes that are placed incorrectly over muscles, or a
poor lead connection, can cause significant noise when the
patient moves.
• Heart rate limits set too close to patient's heart rate. Adjust the
limits as necessary.
