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

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.
