Basics of mechanical ventilation for non-anaesthetists. Part 1: Theoretical aspects.

The expanding number of chronic respiratory diseases and the new Covid-19 outbreak create an increasing demand for mechanical ventilation (MV). As MV is no longer limited to intensive care units (ICU) and operating rooms (OR), more clinicians should acquaint themselves with the principles of mechanical ventilation. To fully acknowledge contemporary concepts of MV, it is crucial to understand the elemental physiology and respiratory machine nuances. This paper addresses the latter issues and provides insight into ventilation modes and essential monitoring of MV.
