Consent | Standard human subjects consent | Standard video release (except for research studies) |
High image quality | Maximize output resolution, minimize intergenerational loss | Same |
High sound quality | Minimize impact of acoustically poor OR environment, facilitate audio de-identification | Better acoustical environment |
Reliability | Operate for extended periods with only minor maintenance or repair | Same |
Ruggedness | Withstand daily transport to and from OR and storage site | Packaging requirements reduced since equipment in fixed location |
Portability | Easily moved and configured by a single operator several times a day | Reduced requirements since equipment in fixed location |
Clinical environmental standards compliance | Conform to OR environmental standards including infection control and material properties requirements | Clinical environmental standards not relevant. Material properties requirements relaxed |
Clinical electrical safety standards compliance | Conform to OR electrical standards including line isolation and hospital grade component requirements | Conformation to OR electrical standards generally unnecessary |
Data stream synchronization | Required for accurate playback and analysis of multiple data streams across all formats | Same—important for effective debriefing |
Ergonomics | Minimize physical size of system to increase portability, reduce barrier hazard and space cost | Larger sizes tolerable. Barrier hazard reduced |
Minimal processing time per case | Reduce overall temporal and monetary cost and allow for maximum amount of processed data | Same |
Optimal image and voice de-identification | Mask identities of subjects without obscuring relevant actions, events or sounds | Less critical since subjects are volunteers |
