Four standard mechanical ventilatory modes were discussed: CMV, A/CMV, IMV, and SIMV. These modes combine attributes and limitations uniquely so that each mode is distinct. Table 1 outlines a summary of these differences. The patient's inspiratory effort triggers mechanical inspiration during A/CMV, and SIMV. Only IMV and SIMV allow spontaneous ventilation and partial ventilatory support, but SIMV increases the work of spontaneous breathing because it necessitates a demand valve. Partial ventilatory support is delivered best with an IMV system that includes a high continuous flow inspiratory reservoir to supply gas for spontaneous ventilation and a threshold resistor expiratory valve.
