Chest Wall Capacity
The Chest Wall Capacity parameter sets the total (combined) intrapleural and lung volumes at
which the chest wall is considered distended. Also, see Chest Wall Compliance Factor and
Distended Chest Wall Compliance Factor.
Default: 3900
Range: 1500 - 3900
Chest Wall Compliance Factor
The Chest Wall Compliance Factor parameter describes the interaction of the chest wall with the
lungs. The Chest Wall Compliance Factor parameter defines the volume-pressure relationship in
the normal operating lung volumes. Once distended, however, the chest wall rapidly becomes much
less compliant (i.e., much “stiffer”) and resistant to further inflation.
Default: 1
Range: 0.15 - 10.00
Distended Chest Wall Compliance Factor
The Distended Chest Wall Compliance Factor parameter, along with the Chest Wall Compliance
Factor parameter, describes the interaction of the chest wall with the lungs. The Chest Wall
Compliance Factor parameter defines the volume-pressure relationship in normal lung volumes.
Once distended, however, the chest wall rapidly becomes much “stiffer” and resistant to further
inflation.
The Distended Chest Wall Compliance Factor parameter must be set to a low value for increased
intrapleural volumes to result in elevated inspiratory pressures with positive pressure ventilation.
Also, see Intrapleural Volume (Vol): (Left and Right).
Default: 1
Range: 0.10 - 10.00
Functional Residual Capacity
The Functional Residual Capacity parameter sets the combined left and right lung volume
remaining at the end of a normal, spontaneous exhalation. This parameter influences the speed of
desaturation during apnea.
Default: 2300 mL
Range: 500 mL - 4000 mL
