Tidal Volume
The Tidal Volume parameter is used to set the tidal volume to a given volume per breath. Once Tidal
Volume is set to a numeric value, arterial oxygen and carbon dioxide values have no effect on the
tidal volume, but continue to influence other components of the physiological models.
For example, with the tidal volume set to 600 mL in the adult simulator, the tidal volume remains a
constant (set) 600 mL even in the event of falling arterial oxygen levels. In such situations, the patient
can only respond to arterial oxygen or carbon dioxide levels by altering the respiratory rate, either
automatically via the model-driven controls or when the Respiratory Rate parameter is adjusted.
Default: Modeled
Range: 0 mL- 2500 mL
Intrapleural Volume (Vol): (Left and Right)
The Intrapleural Vol parameters allow intrapleural volume to accumulate, for example, as happens
during pneumothorax, hydrothorax or hemothorax.
To simulate a pneumothorax, set the corresponding Intrapleural Vol to a value greater than 0 mL.
Values more than 1500 mL reduce the corresponding lung volume significantly. Breath sounds and
chest rise are automatically diminished on the appropriate side due to decreased ventilation of the
affected lung.
Default: 0
Range: 0 mL - 2500 mL
Fraction of Inspired O
2
(FiO
2
)
This parameter is used to simulate changes in the FiO
2
, such as would occur with the administration
of supplemental oxygen.
Default: 21%
Range: 0% - 100%
