Parameter fields
Parameter fields report parameter values and
indicate the alarm status of parameters. Parameter
fields can also report technical conditions such as
disconnected sensors, and so on. For detailed
information regarding the content of parameter
fields for each parameter, see the chapter
"Troubleshooting" on page 509
The following diagram shows a ventilator
parameter field.

Viewing loops
Loops offer important information about the
response of the patient to mechanical ventilation.
You can review loops on two pages:
Pressure/volume and Flow/volume.
Pressure-volume loops illustrate changes in
compliance, resistance, and work of breathing. A
mandatory breath plots counterclockwise, while a
spontaneous breath plots clockwise. Inspiration
starts at a point defined by baseline pressure and
the volume level at the beginning of inspiration.
Flow-volume loops also report mechanical and
spontaneous breaths. Inspiration begins at the
origin and moves upward and clockwise. Expiration
plots below the horizontal axis and progresses
counterclockwise to the original starting point.
NOTE
The following diagram shows a typical parameter
field layout. This layout may change when addi-
tional parameters are put on display. For more in-
formation, see "Parameter fields" on page 62.
