True or False: Pressure support can be set in assist control.

The assertion regarding pressure support being set in assist control is false. In assist control ventilation, the ventilator delivers a set volume or pressure with each initiated breath by the patient, which aims to ensure adequate ventilation and oxygenation. While assist control can include elements of pressure support, traditional assist control does not apply pressure support as it is mainly determined by set parameters.

Pressure support ventilatory modes provide additional pressure during spontaneous breaths to help overcome the work of breathing, which is typically not a feature of assist control ventilation. Therefore, while some ventilators might allow modifications that enable pressure support in conjunction with assist control, it is not standard practice. These contrasting functions highlight the differences in their purposes: assist control primarily focuses on assisting with breathing and ensuring preset tidal volumes or pressures, while pressure support provides additional assistance without preset parameters.
