Dual BiLevel ST
Dual BiLevel Spontaneous Timed.
Combination of BiLevel ST mode and dual BiLevel, allowing spontaneous breaths
during the entire respiratory cycle. The dynamic adaption of the ventilation pres-
sure refers to the mandatory and spontaneous portions of the respiratory cycle.
Breath cycles are defined by setting a fixed respiratory rate (60/f). If spontane -
ous breathing results in the machine's trigger threshold being reached, pressure
support with volume guarantee (= dynamic PSV) will be provided for the spon -
taneous breath. If the patient fails to breathe spontaneously during the cycle,
the machine will initiate a conventional BiLevel breath with volume guarantee
(= dynamic BiLevel) at the end of the calculated cycle time. In patients with no
spontaneous breathing activity, ventilatory support is delivered in the form of the
set mandatory minute volume (f x Vt). In patients who stop breathing for short
periods of time, the mandatory ventilation components provide an intelligent
back-up system for apnoea ventilation.
