11.2 Loops
The ventilator displays the following three loops:
flow versus volume, flow versus pressure and
volume versus pressure.
The ventilator draws three loops before refreshing
the window. Each loop is coloured differently in each
three loop cycle. The colours being red, green and
black.
The ventilator has the ability to store one set of
loops in its internal memory for each type of loop.
These stored loops are date and time stamped.
When the loops are retrieved from the memory they
appear underneath the current active loops.
The loops are accessed by pressing the Display
Graphs Options button . This activates the
Loops and Waveform panel where the appropriate
loop can be selected.
