PSV: Each breath is assisted by the ventilator with a predefined level of<br />
pressure. The duration of the inspiration (inspiratory time) is automatically<br />
adjusted to the patient’s inspiratory time. There<strong>for</strong>e the patient can control<br />
the respiration rate and the inspiratory time. (see also next chapter)<br />
PSV + Volume Guarantee: This combination of <strong>Pressure</strong> <strong>Support</strong> <strong>Ventilation</strong><br />
and Volume Guarantee (VG) allows the patient to control the rate and<br />
inspiratory time; at the same time a set target tidal volume is delivered by<br />
automatic adaptation of the pressure support level. The option Volume<br />
Guarantee is new type of volume controlled ventilation in neonates and is<br />
available with the Babylog 8000plus (<strong>for</strong> more details a separate booklet<br />
about Volume Guarantee is available).<br />
Thus, during SIMV and A/C, inspiratory time is fixed and determined by<br />
ventilator setting. Despite an inspiratory trigger active expiration may occur<br />
in case of inadequately set inspiratory time T I.<br />
