Table 21.15-1. Types of invasive mechanical ventilation


Limited-volume ventilation

Limited-pressure ventilation

Key adjustable parameter


Peak inspiratory pressure

Key monitored parameter

Peak inspiratory pressure

Vt, MV

Main uses

CNS disorders, general anesthesia

Lung diseasesa

a Pressure-limited ventilation is frequently preferred due to pathophysiologic considerations (preventing a barotrauma requires less vigilance than with volume-limited ventilation).

CNS, central nervous system; MV, minute ventilation; Vt, tidal volume.
