MODES OF MECHANICAL VENTILATION
Conventional Ventilation vs. Non-Conventional Ventilation
Conventional ventilation is the primary mode of ventilation we think of when
using a mechanical ventilator. Within conventional ventilation, there are two
primary modes: volume ventilation and pressure ventilation.
Non-conventional ventilation incorporates the following types of ventilators:
- High frequency oscillatory ventilation (HFOV)
- High frequency jet ventilation (HFJV)
- Liquid ventilation
CONVENTIONAL MECHANICAL VENTILATION (VOLUME & PRESSURE)
VOLUME VENTILATION
Volume control ventilation operates under the precept of delivering a set tidal
volume (VT) of air with each breath, regardless of how much pressure it takes to
get that breath in.
Operator sets the following parameters: VT,PEEP, I-time, and rate.
