Narrative:

A single F18 was enroute at 36000 feet and negative rvsm. The F18 notified us of an emergency due to pressurization problems and requested a rapid descent. I was training on the radar position and first issued a descent to 23000 feet. The pilot immediately requested a descent to 10000 feet. At that point; the instructor took over and I moved to the radar assist position to provide assistance. The radar controller pointed the aircraft out to the underlying sector. We were unable to accomplish the coordination with the approach controls before the F18 had penetrated those respective airspaces. Within 1 - 2 minutes; the F18 reported at 10000 feet; VFR and said he had lost cabin pressure and was possibly hypoxic. The pilot also reported that he had the airport in sight and wanted to proceed straight in to the southwest runway. The radar controller issued the tower UHF frequency. More training on military rapid descents and the most needed information to have available to help with coordination procedures to other involved facilities would be helpful.
