ESPIRATORY MECHANICS
Waveforms
Pressure waveforms are displayed next to the Paw parameter box. You can choose to
display either a flow waveform or a volume waveform next to the Vent parameter box
and size the waveform.
To choose between flow or volume waveforms:
1. Click on the Vent parameter box
or
Use the
Menu fixed key (see page 21-11) to get to the Vent menu.
2. Click on
Waveform Display.
3. Select
Flow or Volume, and click to confirm your choice.
To set or modify the size of the waveform:
1. Click on the parameter box labeled Paw or Vent.
or
Use the
Menu fixed key (see page 21-11) to get to the Paw or Vent setup menu.
2. Click on
Paw Scale (on Paw menu) or Flow Scale, Vol Scale (on Vent
menu). Available settings vary according to the type of waveform you wish to
configure. See page 21-8 for more information about these settings.
3. Scroll to the desired size and click to confirm your choice.
Loops
Loops are graphical representations of waveform data collected by the ventilator.
Pressure/Volume loops and Flow/Volume loops offer valuable information about the
patient’s response to mechanical ventilation.
The monitor automatically erases older loops and replaces them with newer ones. The
last loop drawn is the brightest.You can save and display a Reference Loop, which
serves as a useful point of analysis and comparison.
