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 .
