Parameter Description
Vital Capacity
(VC) maneuver Procedure: The clinician instructs the patient to inhale to maximum
capacity at the next inspiration, then exhale completely, followed by a
normal inspiration. The maneuver automatically ends at the next inspiration
(following the maneuver breath) or if 20 seconds elapse without another
inspiration. Available in VCV and PCV. Not available in NPPV.
During the maneuver: Once the maneuver starts, settings for maneuver
breath are mode = CPAP, PEEP = 0 cmH
2
O (during the start of the next
inhalation or exhalation following pressing the start button), and PSV = 0
cmH
2
O. For the breath following the maneuver breath, PSV = 0 cmH
2
O and
PEEP is restored to its original setting. Pre-maneuver settings are restored
during exhalation of the breath following the maneuver breath. Any
scheduled breaths that were postponed by the VC maneuver are delivered
after the maneuver is complete.
Results display: Measured volumes from 0 to 9999 mL are displayed for the
VC maneuver: if measured volume exceeds these limits, only a message (no
data) is displayed. VC is displayed in mL, and is time-stamped based on
ventilator time and date.
Range: 0 to 9999 mL
Resolution: 1 mL
Accuracy: ± 10% of true value
Maximum
Inspiratory
Pressure (MIP)
maneuver Procedure: To perform a MIP maneuver, the clinician asks the patient to
inhale as forcefully as possible against a closed circuit that allows the
patient to exhale through a one-way valve. Available in VCV and PCV. Not
available in NPPV.
During the maneuver: Once the maneuver starts, settings for maneuver
breath are mode = CPAP, PEEP = 0 cmH
2
O (during the start of the next
inhalation or exhalation following pressing the start button), and PSV = 0
cmH
2
O. For the breath following the maneuver breath, PSV = 0 cmH
2
O and
PEEP is restored to its original setting. Any gas exhaled during an MIP
maneuver is not applied to the tidal volume or minute volume calculations.
Results display: MIP is displayed in cmH
2
O, and is time-stamped based on
ventilator time and date. Measured pressures from –100 to +200 cmH
2
O
are displayed for the MIP maneuver: If measured pressure exceeds these
limits, only a message (no data) is displayed.
Range: -100 to +200 cmH
