Respiratory Rate
The Respiratory Rate parameter is used to set the respiratory rate to a given number of breaths per
minute. Once set, arterial oxygen and carbon dioxide values have no effect on the resulting
respiratory rate, but continue to influence other components of the physiological models. The
patient continues to breathe at the set number of breaths per minute, regardless of the arterial
oxygen or carbon dioxide levels.
For example, when the respiratory rate is set to 10 breaths per minute, the respiratory rate remains
at 10 breaths per minute, regardless of arterial oxygen or carbon dioxide levels. In such situations,
the patient can only respond to arterial oxygen or carbon dioxide levels by altering the tidal volume,
either automatically via the model-driven controls or when the Tidal Volume parameter is adjusted.
Default: Modeled
Range: 0 breaths per minute - 40 breaths per minute
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
Tidal Volume Factor
The Tidal Volume Factor (along with the Respiratory Rate Factor) parameter is used to change the
baseline tidal volume (before the control-of-breathing and drug influences are taken into account). A
value of 2 doubles the baseline tidal volume. A value of 0.5 decreases the baseline tidal volume by
50%.
Default: 1
Range: 0.10 - 4.00
TIP: First decrease the respiratory gain factor to reduce the influence of the respiratory control mechanism
on the respiratory rate and tidal volume.
