Non-invasive Ventilation – Basic concepts


In this short video tutorial, I discuss the basics of non-invasive ventilation. We will be covering the following core concepts:


  1. Basic physiology – advantages and disadvantages of PEEP
  2. NIV Terminology – PEEP/CPAP/BiPAP
  3. Which mode to use
  4. How should I be titrating NIV, and what monitoring should I use?


Here is a link also to conceptualise PEEP:

Oxygen Delivery and High Flow Nasal Cannula

In this video tutorial, we will be discussing the use of high flow nasal oxygenation as a therapy in hypoxemic respiratory failure. As we see an increase in the number of patients with COVID-19 pneumonia, this is a therapy that we need to have some familiarity with.

This video will discuss the following:

  1. The benefits of high flow nasal oxygenation
  2. Commencement and titration
  3. When should we bail out?
