Snapshot Types - ZOLL M2 Operator's Manual

Snapshot Types

The ZOLL M2 unit triggers snapshots in response to nine different types of events. Besides the
information in the previous section that is included with every snapshot, the ZOLL M2 unit
stores additional information in each of the following types of snapshots.
Presenting ECG
This snapshot is taken one time at the start of each new rescue incident. The snapshot is not
retaken if the unit is shut off for less than 30 seconds. Additional information in this snapshot
includes 18 seconds of the primary ECG lead waveform recorded after the first ECG leads
connection to the patient.
Note:
Figure 12-3. Presenting ECG Snapshot
ECG Analysis (AED Mode Only)
This snapshot is taken during ECG analysis (shockable rhythm analysis) and records six
seconds of pre-analysis and 12 seconds of ECG data recorded during and after the analysis
period. Additional information in this snapshot includes markers at the beginning and end of
each 3-second segment of the ECG trace used by the analysis to determine whether ventricular
fibrillation or shockable ventricular tachycardia is present. (Each segment is represented at the
top of the strip with either an asterisk (*) for shockable, or a dash (-) for non shockable.)
Analysis results includes the messages: SHOCK ADVISED, NO SHOCK ADVISED, NOISY
ECG, ANALYSIS HALTED.

Once started, ECG recording continues during the presenting rhythm period even if
there is a Leads Off condition.
The date/time printed on the top of the strip is located directly above the data that was
recorded at that time.
