Static compliance
and resistance
(static C and R)
maneuver Procedure: Patient participation is not required, and patient interference
can affect the accuracy of the maneuver. If the patient initiates a breath
when a maneuver breath is scheduled, the ventilator does not perform the
maneuver. Available in VCV only. Not available in PCV and NPPV.
During the maneuver: The ventilator delivers a square waveform, regardless
of the current setting. No other settings change during the static C and R
maneuver. The maneuver is not performed unless a machine or operator
triggered breath is delivered within 20 seconds. The inspiration time must
be between 200 ms and 5 seconds for the maneuver to occur, and the
maximum plateau duration is 2.5 seconds.
Results display: Static compliance is displayed in mL/cmH
2
O. Static
resistance is displayed in cmH
2
O/L/s. All compliance and resistance values
are measured on time or operator triggered mandatory breaths only. During
the last saved Static C and R maneuver, Plateau Pressure (P
plat
) is
measured and displayed as a static value. Static C and R are time-stamped
based on ventilator time and date. Static compliance values from 0 to 350
mL/cmH
2
O and static resistance values from 0 to 400 cmH
2
O/L/s are
displayed: If either value exceeds its limits or a stable plateau pressure
cannot be achieved, only a message (no data) is displayed.

Inspiratory time
divided by total
breath time (TI/
TTOT). Calculated inspiratory time divided by total breath time, or percent
inspiratory time. An eight-breath running average. Available in VCV, PCV,
and NPPV.
Applicable to spontaneous and pressure-supported breaths only. If there
were no spontaneous or pressure-supported breaths within the last one
minute, - - - - is displayed.
