Chest X-Ray for Respiratory Care: Systematic Read | Pulmonics 23/100

What a chest radiograph physically measures, why a border vanishes when lung next to it fills with fluid, how to read a film in a fixed order, and how to check and correct an endotracheal tube, central line, nasogastric tube and chest tube. Taught by Kasim Hassen, MD, RRT. Part of Pulmonics — respiratory care from first principles.
