This episode was shot live twice on the same day. Once for east coast viewers and again for west coast viewers.
This episode does not use any of the soundtrack music normally heard in the series, such as the rapid beat music heard during every trauma procedure.
To give this episode a more 'documentary-like' style, it breaks with the normal style of the series. For example, the episode uses handheld cameras only (and lacks the steadicam which can be seen as a trademark of the series). Also this is the only episode of the entire series which was filmed in the 4:3 aspect ratio.
This episode was broadcast live.
