Detailed Descriptions for the elements in the Media resource.
| Media | |
| Element Id | Media | 
| Definition | A photo, video, or audio recording acquired or used in healthcare. The actual content may be inline or provided by direct reference.  |

| Type | DomainResource | 
| Summary | false | 
| Media.identifier | |
