ZOLL M Series Defibrillator Rev YH - Manual (Page 61)

ECG Monitoring
9-5
messages are only displayed the first time the
augmented or V-leads are selected. They are not
redisplayed as the user cycles through the Lead
selection.
Simultaneous 3 Lead Printing (If Configured)
To simultaneously print 3-leads of the patient ECG when
leads are selected, a 5 lead ECG cable must be in use
and the “Print 3 Leads When Leads are Sel” option must
be selected as “YES” in System Configuration (Refer to
the M Series Configuration Guide).
The lead selection shown on the display will always be
the top ECG printed on the recorder strip. Signals
simultaneously recorded by the other leads of each
triplet (limb leads, augmented leads, etc.) will be printed
below this trace. For example, if AVR is selected, the
recorder will simultaneously print AVR (top) followed by
AVL (middle) and AVF (bottom).
Changing from 5 Lead to 3 Lead ECG Monitoring
To change from 5 lead ECG monitoring to 3 lead ECG
monitoring, perform the following:
• Turn the unit OFF for at least 10 seconds.
• Disconnect the 5 lead ECG patient cable from the back of
the unit.
• Connect the 3 lead ECG patient cable to the back of the unit.
• Turn the unit ON.
Note: The message, “ECG LEADS OFF will appear on
the display if the unit was not turned OFF for at
least 10 seconds after the 5 lead ECG cable has
been removed even if leads are properly attached
to the patient.
Vital Signs Trending
Some M Series models include a vital signs trending
feature that samples the instantaneous values of
monitored physiological parameters and stores the
sampled data in a log that includes the time these values
were recorded. These vital signs include the patient’s
heart rate, SpO
2
, end tidal CO
2
, respiration rate and
noninvasive systolic, diastolic and mean blood pressure
values.
Stored trend data may then be viewed in tabular form on
the M Series display or printed by the unit’s stripchart
recorder.
If the M Series is configured with trending enabled, the
values of monitored vital signs are sampled once each
minute and stored in the unit’s trend memory. Storage is
provided for 24 hours of one minute trend records. When
this storage is filled, the newest trend record replaces the
oldest trend record. Additional trend records will be
stored whenever a parameter alarms or an NIBP
measurement is taken. Note that these additional
records will decrease the overall number of one minute
trend records that can be stored in the unit’s memory.
Viewing Vital Signs Trending Data on the Display
The display for vital signs trend data always shows the
time of the recorded data, the heart rate/pulse rate and
the SpO
2
. The date of the recording appears at the top of
the trend display. EtCO
2
and NIBP are optionally
displayed based on the configuration of the unit.
To select either EtCO
2
or NIBP data for viewing:
1. Press the SUMMARY button.
2. Press the Trend softkey on the Summary menu.
3. Use the Select softkey to highlight either EtCO
2
or
NIBP.
4. Press the Enter softkey to select the desired option.
To view only SpO
2
data when multiple parameters are
installed on the unit, use the Select softkey to highlight
SpO
2
from the Trend submenu, then press the Enter
softkey.
If only one parameter is installed on the unit, the trend
screen automatically displays when the Trend softkey is
pressed.
Not all trend data can be displayed on the monitor at the
same time. However, the screen can be changed to
display additional recorded data. Using the Zoom
softkey, the user can view trend records taken at 1
minute, 5 minute, 10 minute, 15 minute, 30 minute, and
60 minute intervals. Data is presented with the newest at
the top to the oldest at the bottom of the display.
If an alarm occurs while the unit is monitoring vital signs,
such as an NIBP alarm, the unit records the data at the
moment of the alarm independent of the standard one
minute interval recording.
An alarm condition is indicated on the trend display by
placing brackets around the alarmed parameter(s).
Invalid data is indicated on the display by substituting a
dashed line for the actual data. Invalid data may occur,
for example, when the measuring probe or device is not
properly connected to the patient.
