Snapshots and events
need more memory than the previous ones. Therefore, more than one snapshot
may have to be erased.
To erase snapshots, you must discharge the patient/end a case. Note that this will not
erase just the snapshots but also all other patient and trend data from the monitor
and a connected PDM or TRAM, and will also return monitor settings to their defaults.
1. Select the patient information area on screen, or select Data & Pages > Start
/ Reset Case (OR and PACU software packages) or Admit/Discharge (other
software packages).
2. Select Patient > Discharge Patient .
3. Select Yes .
Snapshots and alarm history
CAUTION
— MEASURING DATA STORED IN ALARM HISTORY — Waveform
data is stored in the alarm history using compression
technology that may not allow perfect reconstruction of
the waveform data when subsequently viewed. Although
differences occur relatively frequently and are usually
very minor, users are urged to verify diagnostic waveform
measurements with the waveform data from realtime graph
strips.
When a PDM or telemetry transmitter is connected to the monitor, the saved alarm
history and ST history will be transferred to the monitor. One snapshot is created
for each alarm history.
The PDM or a telemetry transmitter alarm history has 10 seconds of waveform data
from two or three ECG leads and the first arterial invasive pressure line. The snapshot
will display waveforms only if the snapshot field configuration includes the same
ECG waveforms and/or arterial invasive pressure channel. Otherwise, no waveform
data is displayed.
A snapshot is sent to the CARESCAPE Network if it contains one of the following
waveforms: ECG lead I, II, III, or Va, or any arterial invasive pressure.
Snapshot transfer to PDM
Telemetry transmitters store snapshots independently. They are stored on the PDM
when they are transferred by the monitor. Only snapshots created by arrhythmia
alarms are transferred. Manual snapshots and snapshots triggered by SpO
2
high/low
and arterial IP high/low alarms are not stored to the PDM.
ST snapshots
Creating ST snapshots manually
An ST snapshot displays QRS complexes.
