Once all ventilation parameters are set on the ventilator, it calculates TEXP based on TINS and Rate, thus obtaining all ventilation
control times.
1
Represents a PCV (pressure controlled) cycle during TINS;
2
Represents a spontaneous breathing cycle of the patient WITHOUT PRESSURE SUPPORT;
3
Represents a PCV (pressure controlled) cycle when SIMV Period has elapsed;
4
and
5
Represents the spontaneous breathing cycle of the patient WITH PRESSURE SUPPORT, with cycling occurring
by flow, when this reaches a value between 5% and 80% of the peak value read. Percentage of peak flow in which cycling
occurs from inspiratory phase to expiratory phase is programmable. Rise time (TRISE TIME) also applies to pressure support
(see PCV).
6
If patient performs inspiratory effort, in the end of SIMV period (TSIMV), there is a timing window of the controlled ventilation
cycle, which is ‘open’ from 0.75 x TSIMV, i.e.,
in the last quarter of SIMV Period, a timing window opens for the mandatory
ventilation cycle. The information of what type of trigger activated the inspiratory cycle is reported in the message area and
screen status.
•
Default values are only for initial reference. Reset ventilation parameters as needed by the
patient.
Note
•
Respiratory rate monitored can be higher than respiratory rate set, because the patient can breathe
spontaneously during mandatory ventilation cycles
•
Pressure support (ΔPS) is a value above PEEP and can be adjusted b 5 cmH2O and PINSP
-
PEEP.
