APPENDIX 1 DESCRIPTION OF VENTILATION MODES  

Appendix 1.1 Description of CMV / VCV mode  

In CMV/VCV mode (Controlled Mandatory Ventilation / Volume Control Ventilation) the patient 
receives  the  set  tidal  volume.  Flow  curve  is  rectangular  or  decreasing  (as  shown  below),  ac-
cording to doctor’s choice. The device provides the set volume of a respiratory cycle at the set 
respiratory rate with the set duration of the respiratory cycle.  

 

Figure. App. 1.1 – Graphs of pressure (top) and flow (bottom) in CMV / VCV modes with de-

creasing flow.  The shaded area shows volumes of both inspiration and expiration 

 

In the CMV/VCV mode possibility of support of the spontaneous breaths initiated by the patient 
is  provided.  This  possibility  is  realized  by  setting  of  the  trigger  sensitivity.  Automatic  breath  is 
triggered when trigger operates within a trigger window. 

In CMV/VCV modes user also can set the inspiration pause by Tplat parameter.
