B.2 Mandatory modes
The mandatory ventilation modes ((S)CMV and P-CMV) deliver
time-cycled mandatory breaths, volume-controlled or pressure-
controlled, respectively.
When the patient triggers, or the operator initiates a breath,
the respiratory rate increases, while both the inspiratory time
and the tidal volume (for (S)CMV), or the inspiratory pressure
(for P-CMV) remains constant. The minute volume increases
as a result.
B.2.1 Synchronised controlled mandatory ventilation
((S)CMV) mode
The (S)CMV mode provides volume-controlled mandatory
breaths only. The controls active in the (S)CMV mode are
shown in Figure B-1. The tidal volume (Vt) setting defines the
delivered volume. The Rate and breath timing settings (see
Appendix J.4.1) define the breath cycle timing. Breaths can be
triggered by the ventilator, patient, or operator.
In this mode, the operator sets the Vt, the Rate and other
breath timing controls, and the FlowPattern. As in all other
modes, the operator also sets the PEEP/CPAP and Oxygen,
and the pressure or flow trigger when required.
