Description : Check out this medical PowerPoint presentation titled "Comfort and Sedation".

This medical PowerPoint presentation talks about Comfort and Sedation. Comfort and sedation are related concepts, but they are not exactly the same thing. Comfort refers to a state of physical and emotional well-being, free from pain, discomfort, and distress. Sedation, on the other hand, refers to a state of reduced consciousness or awareness, often induced by medication.
