Tutorial 13 Mechanisms of Hypoxia-Hypoxemia

If you treat patient with hypoxic respiratory failure you really need to understand what is going on in their lungs. These two tutorials look at diseases of the lung parenchyma and how blood flow and gas flow interact. This tutorial focuses on alveolar oxygen content and how it is impacted by disease. I explain the concept of airway closure (which will will revisit in detail several times during this series), stale alveolar gas, the various causes of atelectasis and the six S approach to figuring out what is going on in the airways (Slimy, Soggy, Sticky, Stiff, Squished, Shunty). ‪@ccmtutorials‬ www.ccmtutorials.org www.ccm-tutorials.com Contents 00:08 Introduction 00:25 Review of Previous Tutorial 01:50 Contents of This Tutorial 02:30 Clinical Scenario Trish (59y) 03:30 Causes of Hypoxemia 05:10 Alveolar Blood Flow 07:50 Understanding Oxygen Flow From the Airways to the Capillaries 09:40 Airway Closure 11:25 Stale Alveolar Gas 12:25 Atelectasis after airway closure (inc. hypoxic pulmonary vasoconstriction) 13:40 Atelectasis and Right to Left Intrapulmonary Shunt 15:00 Types of Atelectasis 15:25 Compressive Atelectasis 17:10 Obstructive Atelectasis 18:00 Absorption Atelectasis - consequent of hyperoxia 21:00 Lung Abnormalities Resulting in Hypoxemia 24:30 Snotty/Slimy Material in Airways - Resulting in Stale Alveolar Gas 25:00 Soggy Lungs (pulmonary edema) 26:25 Stiff Lungs 27:20 Sticky Lungs 29:00 Squished (externally compressed) Lungs 30:30 Shunty (right to left intracardiac shunt) 30:20 Review of Tutorial 31:10 Preview of Next Tutorial
