5 Using Print and Waveform Freeze
Pressing the
Print button prints the waveforms (and current measurements) if the waveforms are
displayed. If a screen of trend data is displayed, all the trend data is printed. Atlas Monitors without
printers have a
Freeze button that halts the waveform display for 10 seconds for examination.
Print or Freeze - Except for model 623xx, the
printer is optional. Your Welch Allyn Atlas
Monitor has a printer if there is a button labeled
Print beneath the screen. If there is no printer, this
button is labeled Freeze .
Printing waveforms - To print the waveforms
and the current measurements, press
Print while
the screen shows the waveforms. When you print
waveforms, the waveforms are printed starting
from 9 seconds before you pressed the
Print
button until 6 seconds after you pressed it. The
numeric data is captured and printed at the
moment that the
Print button is pressed.
Printing trend data – To print trend data, press
Trend to view the data on the screen, then press
Print . If trend data is displayed and you want to
print the waveforms, press Trend to go back to
the waveforms, then press Print .
Note: If the monitor was not turned off between
patients, the printed trend data will include that
recorded from previous patients. Trend data is
only erased when the unit is turned off.
Printing On Alarm - If the Print On Alarm
configuration is set to Yes in the Advanced
Configuration screen, then a new Patient Alarm or
a new Measurement Invalid Alarm will trigger a
print of the currently configured waveforms and
current measurements. The alarming values are
marked with asterisks in the printed report. The
printout shows 9 seconds of waveform before the
alarm and 6 seconds after the alarm.
Note: If multiple alarms occur at the same time, it
is considered one new alarm and only one print
occurs. If the Atlas is printing and one or more
new alarms occur during the print cycle, an
additional print will occur after the first print.
The Atlas does not issue one print per alarm.
A Print On Alarm will not occur for low battery
alarms or for instrument problem alarms. If alarms
are silenced or suspended, a Print On Alarm will
not occur, but if the alarm is still active when the
silence period is over or when the alarm is
unsuspended, a Print On Alarm will occur.
Freeze - If your monitor does not have a printer, it
has a
Freeze button. Pressing this button halts the
waveforms. You can then examine something on
the screen before it is overwritten. The heart rate
and alarm status are not updated during a freeze.
Three events can end the freeze period and return
the waveforms to the normal, updating mode:
• Pressing Freeze a second time ends the
freeze period.
• Ten seconds after you press Freeze , the
waveform starts again, automatically.
• Any patient alarm or instrument problem
alarm that affects the frozen display will
end the freeze period.
Note: No data is lost during the freeze period.
Data is still added to the trend list during this
time.
ECG waveforms – Changing the ECG
bandwidth affects both the displayed and printed
waveforms. The bandwidth choices in Advanced
Configuration are:
•
Monitor — a narrow bandwidth, which
produces a cleaner waveform printout.
•
Extended — a wider bandwidth, which
allows better viewing of the ST segment
and enhanced detail of the pacemaker
signals in a paced patient.
Note: It is normal for the ECG baseline to wander
slightly in Extended bandwidth.
