Volume-Control to Pressure Control

Image 1: The Settings of VC-CMV. The settings highlighted in yellow are associated with patient-ventilator asynchrony. 

VC-CMV is likely the most utilized mode of mechanical ventilation. This is due to a few a reasons:

     1. VC-CMV is a standard mode on almost every intensive care ventilator (table 1).

     2. VC-CMV is one of the first modes of mechanical ventilation.

     3. VC-CMV is easy to understand in both theory and operation.

     4. VC-CMV is the standard of care when ventilating patients with Acute Respiratory Distress
          Syndrome (ARDS) and Acute Lung Injury (ALI).

In this months Canadian Journal of Anesthesia authors of the article "Brief Review: Theory and Practice of Minimal Fresh Gas Flow Anesthesia", conclude that with newer anesthesia delivery systems that using minimal fresh gas flow and third generation of inhaled anesthetic agents is a safe technique with many benefits [1]. 

The authors review advantages, potential limitations, and safety considerations when utilizing minimal fresh gas flow technique (mFGF).
