Correct Answer » A Explanation

Ans:A. Assist Controlled Mode.

Modes of ventilation.

• Assist mode, control mode, and assist-control mode

• A basic distinction in mechanical ventilation is whether each breath is initiated by the patient (assist mode) or by the machine (control mode). Dynamic hybrids of the two (assist-control modes) are also possible.

• Assist Mode:

• In this mode, the ventilator supports every breath, whether it’s initiated by the patient or the ventilator.

• Control ventilation :

• The respirator delivers the preset volume or pressure regardless of the patient’s own inspiratory efforts.

• Volume control (VC) means that both volume and flow are preset prior to inspiration.

• Pressure control (PC) means that inspiratory pressure is preset.

• Assist -Controlled:

• The first breath in this cycle is one initiated by the ventilator. The second breath is the patient triggered breath. There is a slight dip at the beginning of the breath, which is the patient creating a negative pressure. The ventilator senses this and delivers another breath.
