This reddening should substantially lessen within 72
hours.
There have been reports of burns under the anterior
electrode when pacing adult patients with severely
restricted blood flow to the skin. Prolonged pacing
should be avoided in these cases and periodic
inspection of the skin is advised.
There are reports of transient inhibition of spontaneous
respiration in unconscious patients with previously
available units when the anterior electrode was placed
too low on the abdomen.
This device must not be connected to internal
pacemaker electrodes.
Pediatric Pacing
Pacing can be performed on pediatric patients weighing
33lbs / 15kg or less using special ZOLL pediatric MFE
Pads. Prolonged pacing (in excess of 30 minutes),
particularly in neonates, could cause burns. Periodic
inspection of the underlying skin is recommended.
Monitor
The patient’s ECG is monitored by connecting the patient
to the unit via the 3 or 5 lead patient cable, MFE Pads, or
through the paddles. Four seconds of ECG is presented
on the display along with the following information:
• averaged heart rate, derived from measuring R to R
intervals
• lead selections - I, II, III, aVR, aVL, aVF, V (with ECG
cable), PADDLES, or PADS
• ECG size - 0.5, 1, 1.5, 2, 3 cm/mV
• pacemaker output in milliamps (Pacer version only)
• pacemaker stimulus rate in pulses per minute (Pacer
versions only)
• defibrillator output in joules
• other operational prompts, messages, and diagnostic codes
Monitoring or diagnostic ECG bandwidth is selectable.
Recorder Function
A strip recorder is provided to document events. The
strip recorder normally operates in the delay mode (6
seconds) to insure capture of critical ECG information.
The recorder may be activated manually by pressing the
RECORDER button. It will be activated automatically
whenever a defibrillation SHOCK is delivered, a heart
rate alarm occurs, or the rhythm analysis function is
activated. The strip recorder may also be configured not
to print during these events.
Paddle — Electrode Options
The M Series products will defibrillate, cardiovert and
monitor ECG using either defibrillation paddles or ZOLL
Multi-Function Electrode (MFE) Pads.
The pacer version of the M Series will also pace using
ZOLL MFE Pads.
Energy Select, Charge, and Shock controls are located
on the paddles and front panel. When using MFE Pads,
the controls on the front panel of the unit must be used.
To switch between paddles and MFE Pads, remove
Multi-Function cable from the apex paddle and connect
the MFE pads to the Multi-Function cable.
The Advisory function cannot be activated unless MFE
Pads are attached to the Multi-Function Cable and used
as the ECG monitoring lead.
Note: The MFE Pads, Pediatric MFE Pads, stat•padz,
and ECG electrodes (not the ECG cable) are
disposable, single-use items.
Batteries
The M Series products use easily replaced sealed, lead-
acid battery packs that, when new and fully charged, will
provide at least 2.5 hours of monitoring. Use of the
defibrillator, stripchart recorder, and pacemaker will
reduce this time.
When a “LOW BATTERY” message appears on the
display and the unit emits two beeps in conjunction with
the displayed message, the battery must be replaced
and recharged.
Internal Battery Charger
Battery charging can be performed within the device via
AC mains, an optional DC input, or by using an external
battery charger.
When the M Series products are plugged into AC mains
or to a DC power supply, the CHARGER ON indicators
will operate in the following manner:
The orange-yellow CHARGER ON indicator will
illuminate continuously whenever; the device is turned
OFF and charging the battery or turned ON with a
battery installed.
The green CHARGER ON indicator will illuminate
continuously whenever the unit is turned OFF and the
installed battery has been fully charged to present
capacity.
The green and orange-yellow Charger On indicators will
illuminate alternately when no battery is installed in the
unit or a battery charging fault has been detected.
When the device is not connected to AC mains, the
CHARGER ON indicators will remain extinguished.
If your M Series unit does not function as expected, see
the AC Charger Troubleshooting section on page B-7.
