>I've been diving for 16 years, but I never expected to use the skills I've learned to save a life. Before we got in the water on that beautiful blue day on the Great Barrier Reef, I was filled with anticipation about seeing hammerheads, mantas and reef sharks. But soon I would find myself at the right place at the right time.
>We were on our way to a bommie (Australian slang for coral formation) to check out a cleaning station when we heard banging on a tank. We assumed someone had spotted a shark or manta, but none was visible — nor could I see a diver banging on his or her tank. The banging continued insistently until finally I spotted a diver ascending diagonally toward my friend Heidi. Just as he reached her, he froze and went limp. Heidi later said, "I saw his mouth open a few times and take in water. I saw him go unconscious and have a full-body seizure and then slump." I quickly started finning toward the lifeless diver, hoping to not lose too much time.
>The diver was pale, open-eyed and unresponsive. There was a little bit of water in his mask, and his mouth hung slack without his regulator. Not a single bubble came out. I knew that the top priority upon finding an unresponsive diver at depth was getting him to the surface as quickly as possible.
>Energized and acting on instinct, I grabbed the diver, who was much bigger than me. We were slowly sinking when my friend Rod, Heidi's husband, showed up by my side. We couldn't inflate the diver's BCD at first, but as we kicked upward in an emergency ascent Rod reached for the diver's tank valve and turned the knob — that's when we realized the tank was only partially open.
>At the surface I yelled and used my Dive Alert audible signaling device as Rob and I worked to keep the diver afloat with his head above water. Fluid and blood were coming from the diver's mouth.
>The tender reached us quickly, and we were able to get the unresponsive diver on board without too much difficulty. As soon as we reached the liveaboard, the crew positioned the diver on the deck, began administering oxygen and hooked him up to a defibrillator. Two doctors who were on board, one from Singapore and one from China, also helped.
>I was traumatized by the whole event. It's hard to explain what it felt like to have had someone's life in my hands. Immediately after the rescue I couldn't help but think that if I had messed up, the diver would have been gone. The doctor who treated him was very generous and spoke to me on the phone on several occasions. He helped me through the trauma and the mixed bag of emotions that overwhelmed me. He said it was a miracle that the diver survived with no neurological damage and that he might not have been so lucky had he been submerged for much longer. "Focus on the blessing of the life you saved, Christina, and nothing else that might have been or could have been," he said to comfort me.
>The fact that the diver's tank valve was barely open meant he had enough airflow to descend but that once he was three atmospheres underwater his nearly closed tank couldn't provide him with sufficient air. He did not approach his buddy or dive guide but panicked and bolted for the surface, banging on his tank as he finned. Later it was discovered that he had failed to disclose to the liveaboard that he was taking three medications that could possibly affect his well-being while diving. Hiding the truth is a dangerous game.
>It is a blessing that the diver lived, and fortunately he did not suffer a lung overexpansion injury. Salt-water inhalation, however, damaged his alveoli (the air sacs in the lungs).
>There are reasons why specific rules and guidelines were developed for scuba diving: The rules reduce the likelihood of dive accidents. No one is exempt — it is imperative that all divers follow protocol. The purpose of the predive safety check is to give our dive buddies a chance to catch anything we might have missed. Never be in a hurry before a dive; rushing can lead to omission of crucial steps such as double checking that the tank valve is fully open.
>Dive safety experts now advise divers to always dive with their tank valves completely open — not turned back a half or quarter turn. Find out more at AlertDiver.com/Tank-Valves-and-Out-Of-Air-Emergencies.
