A diver has been rescued after getting into trouble exploring a sunken steam ship.

The woman was diving the wreck of the Shuna in the Sound of Mull when she developed a case of the bends on Friday morning.

Oban RNLI took the woman and her diving partner back to shore after they were assessed by the team's doctor.

She was then driven four miles to a recompression chamber at Dunstaffnage for treatment.

A spokesman for Oban RNLI said: "Oban Lifeboat is fortunate to have a doctor as one of her crew, and with many years of experience working with divers in this situation his input is invaluable in providing excellent casualty care.

"When the lifeboat arrived alongside the dive boat at 11.16am the diver and dive-buddy were assessed by our doctor and the decision was made to transfer the divers back to Oban as quickly as possible.

"Upon arrival back in Oban the diver was transferred to a waiting ambulance which took the diver on the four mile journey to the recompression chamber at Dunstaffnage."

The Shuna sank in May 1913 while carrying a load of coal from Glasgow to Gothenburg. The steam ship hit rocks near Lochaline and now lies in nearly 100ft of water.

The bends is a medical condition often caused when divers surface too quickly from a deep dive. This causes gases like nitrogen to dissolve rapidly inside their bodies.

The painful and often fatal condition can be treated by spending time in a recompression tank, which allows gases to dissipate slowly.
