Pressure Sore Assessment and Staging

The video tutorial discusses pressure sores, focusing on their grading and clinical appearance. It explains the four grades of pressure sores, from Grade 1 with non-blanching hyperemia to Grade 4 with infective necrosis. The tutorial also provides guidelines for identifying established pressure sores, highlighting signs like necrosis and the healing process involving granulation and epithelialization.

What are the two main aspects to consider when a pressure sore has already occurred?

What happens to the underlying muscle in a Grade 3 pressure sore?

• It swells and becomes inflamed
