17.3. Strip Chart Recordings
Strip chart recordings contain a waveform area that includes a 40 mm-wide grid
with descriptive text above and below the grid. The waveform grid has major
divisions at 5 mm intervals and minor divisions at 1 mm intervals, in both the x
and y direction.
The waveform area contains one or two user-selected waveforms. If one
waveform is selected, the waveform uses the entire grid. If two waveforms are
selected, each waveform uses half of the grid, with no overlap. If the same
waveform is selected for both waveform channels, it is treated as a single
waveform selection (i.e., one waveform using the entire grid).
Any displayed waveform may be selected for printing. The printed waveform
scaling and lead-off handling matches that of the displayed waveform. The
descriptive text above the waveform area describes the top waveform. The text
below the waveform area describes the bottom waveform (or is left blank if only 1
waveform is printed). The descriptive text includes the waveform label, the
waveform scale and the associated parameter value. For ECG waveforms, the
frequency response (fixed at monitor) is printed. Additionally, the descriptive
text above the waveform area includes the current date/time, the waveform delay,
and the sweep speed (fixed at 25 mm/sec).
Strip chart recordings contain a trailer with the current date/time and a list of all
parameters (label, value, and units of measure) that are currently on display.
Alarm-generated strip chart recordings contain a header with an "Alarm
Snapshot" banner and a list of the parameters (label, value, and units of measure)
that are currently in alarm.
When a strip chart recording is in progress, you can cancel it by pressing the Print
key.
