Operation
In this ventilation mode, the “controlled” cycle (PCV) delivers a fixed pressure at the set frequency RR
SIMV. A SIMV period arises from this frequency.
E.g. for a SIMV frequency set to 10 cycles per minute, the SIMV period between two “controlled” (PCV)
cycles is 6 seconds.
In the event of absence of patient respiratory activity, this mode provides the guarantee of controlled
ventilation (PCV).
When the patient has regular and detectable respiratory activity, the unit responds by:
•
supplying a “spontaneous” cycle (PSV) if the time elapsed since the last “controlled” cycle is less
than the SIMV period,
• supplying a “controlled” cycle (PCV) if the time elapsed since the last “controlled” cycle is greater
than the SIMV period.
If patient respiratory activity declines again after a “spontaneous” cycle, Monnal T60 Advanced waits
for the SIMV period to expire before triggering a “controlled” cycle (PCV).
Insufflation in a spontaneous cycle with pressure support ends:
•
If the flow rate falls below the set expiratory threshold (E. Trig);
• If the patient makes an expiratory effort;
• or if the insufflation time reaches the maximum Ti setting (Timax).
Note: Apnea ventilation can be activated; the apnea parameters should be suited to the con-
dition and requirements of the patient.
4.6.10 APRV (Airway Pressure Release Ventilation)
Principle
The APRV mode is defined by spontaneous ventilation, and alternation between a constant high pres-
sure level and a lower pressure level.
