Breath Analyser
The breath analyser changes the display to a graphical format, like an oscilloscope.
This can be useful to evaluate a patient’s breathing pattern and to assess the
effectiveness of the triggering.
The pressure and flow waveforms are stored then displayed on the screen.
•
The screen displayed shows the stored information from the previous breath.
•
The width of the trace is the period of the back up rate, displayed in seconds
on the X axis. E.g. if back up rate is set to 10BPM, the trace width represents
3 seconds.
•
The pressure in cm H
2
O is displayed on the left Y-axis and relates to the RED
trace.
•
The flow in litres/minute is displayed on the right Y-axis and relates to the
BLUE trace.
•
The insp trigger (IT) and exp trigger (ET) points are marked along the X-axis
as they occur.
•
The display may be “frozen” by pressing the
◄ -
button. Press the
+ ►
button to restart the display.
