Deferra

Controls when intraoperative alerts and guidance are shown. It suppresses unnecessary output while the operative course is stable, withholds guidance when the view is inadequate, and directs view correction before guidance resumes.

Case loading. Deferra establishes operative context and controls interruption. Guidance is shown only when the operative view and accumulated evidence support it.

Four questions Deferra checks

Which instrument answers each question. Each check is performed by a CMH Scientific instrument; Deferra combines them to route assistance.
