(from uptodate-Modes of mechanical ventilation)

Volume-limited ventilation (also called volume-controlled or volume-cycled ventilation)

1. 需要設 peak flow rate, flow pattern, tidal volume, respiratory rate, positive end-expiratory pressure (applied PEEP), & FiO2

2. Inspiration ends after delivery of the set tidal volume.

3. (I:E) ratio 由the peak inspiratory flow rate決定：增加的peak inspiratory flow rate會減少inspiratory time而增加expiratory time

4. 氣道壓力(peak, plateau, and mean) 決定於both the ventilator settings and patient-related variables (eg, compliance, airway resistance).

5. 高氣道壓力的原因有許多：large tidal volumes, a high peak flow, poor compliance (eg, acute respiratory distress syndrome, minimal sedation), or increased airway resistance
