Interpreting Arterial Blood Gases - ABGs

Learn to interpret arterial blood gases (ABGs) in this comprehensive 32-minute video lecture by Michael Greenlee for OPENPediatrics. Explore the differences between arterial and venous blood gases, understand the components of ABGs, and delve into acid-base balance principles. Examine normal ranges and various acid-base imbalances, including respiratory acidosis and alkalosis, as well as metabolic acidosis and alkalosis. Study their causes, signs, symptoms, compensatory mechanisms, and appropriate interventions. Apply your knowledge through four case studies, enhancing your ability to diagnose and manage ABG imbalances in critically ill children. Gain valuable insights into troubleshooting mechanically ventilated patients and strengthening respiratory muscles.
