Set-point parameter is a set-point for PaO

progressive stimulation of spontaneous minute ventilation occurs. Both tidal volume and respiratory
rate rise, which under appropriate conditions results in PaO
that influence this control effort include baseline tidal volume, baseline respiratory rate, respiratory
gain, O
consumption, respiratory quotient, lung compliances, chest wall compliance, bronchial

resistances, the presence of artificial airways in the simulator and the inspired gas mixture. Minute
ventilation is not affected for PaO

I to E Ratio (1:X)
The I to E Ratio (1:X) parameter sets the inspiratory-expiratory (I:E) ratio for spontaneous ventilation. At
the default setting, the time for exhalation is twice that of inhalation.
Default: 2
Range: 0.5 - 7.0
