Saving reference loops
Displaying loops
You can save up to six pairs (flow/volume and pressure/volume)
of reference loops. Both loops are saved at the same time. When
more loops are saved, the most recent one is erased from
memory.
The loops allow you to visually detect changes in the patient’s
respiratory status.
