Modes of ventilation

Volume Controlled Ventilation

◆ AV-S delivers a mandatory set volume of gas at fixed breath intervals.

The Patient is making no respiratory effort.

♦ AV-S is volume limited and time cycled.

♦ Tidal volume setting range, 20 to 1600ml.

Inspiration terminated after a preset time.

Modes of ventilation

Airway Flow and Pressure Patterns

Modes of ventilation

Volume ventilation parameter limits:

Tidal volume adjustable from 20 – 1600 mL

Rate adjustable from 4 – 100 bpm

I:E ratio adjustable from 1:0.3 – 1:8

♦ Peep 'Off or adjustable from 4 – 20 cmH $ _{2} $O

Inspiratory pressure limit from 10 to 80 cmH $ _{2} $O

Inspiratory pause 0-60%

Does not affect I:E ratio

Sigh 1.5 x Set Vt

Adjustable 1:10 to 1:100 breaths
