Sounds like a pretty serious case. Just pray for the best for the unconscious diver. From reading Wikipedia of it, this wreck is deep. SS Andrea Doria - Wikipedia
"Due to the luxurious appointments and initially good condition of the wreck, with the top of the wreck lying initially in 160 feet (50 m) of water, Andrea Doriahas been a frequent target of treasure divers. It is commonly referred to as the "Mount Everest of scuba diving."[24] The comparison to Mt. Everest originated after a July 1983 dive on the Doria by Capt. Alvin Golden during a CBS News-televised interview of the divers following their return from a dive expedition to the wreck aboard the R/V Wahoo. The depth, water temperature, and currents combine to put the wreck beyond the scope of recreational diving. The skills and equipment required to successfully execute this dive, such as use of mixed gases and staged decompression, put it in the realm of only the most experienced technical divers. The wreck is located near 40°29.408′N 69°51.046′W.[25]"
Currently, it's more like 200-240 feet deep. I'm not discounting the seriousness of the dive, but it isn't anywhere near the "Mount Everest of scuba diving", at least not today.
