    生命的教训:水下抽筋 被流吹走 Gets Swept Away

    一个小问题,比如腿抽筋,会迅速升级成一个大的问题。

     

    被流吹走

    摄影师与潜伴分开了让她陷入麻烦。

    Angie在石头上方盘旋,她放慢了她的呼吸。她试图使自己隐藏在水中,希望那只小鲇鱼会再次出现。她真的很想它从洞里出来,并拍下照片。

    最后,Angie拍到了一个完美的角度,拍了三张照片,被Angie的水下闪光灯吓到,小鲇鱼消失了。Angie离开了珊瑚礁,四处寻找她的潜伴,Cliff。

    潜水员

    Angie和Cliff多年来一直在一起潜水,他们很合拍。Angie是一名狂热的水下摄影师,但Cliff喜欢在水里闲逛,欣赏风景。他有在珊瑚礁里寻找小动物的第六感,所以他经常帮助她寻找下一个主题的生物。Cliff从未离Angie太远,他们两个都不喜欢成为一个坏的潜伴。他们是一个很好的团队,在水里互相支持。他们都40多岁,身体健康。

    在潜水的早上,Cliff并没有百分百的感觉太好,但他并没有让这个感觉影响到他的潜水。他们有一段时间没有一起潜水了,他不想让Angie失望。他没有吃早餐,他希望他的胃能安定下来。

    那一次潜水

    这是一次小团队潜水——不超过六个潜水员,这对Angie和Cliff来说非常好,这减少了潜水员干扰或捣乱Angie拍摄照片的机会。

    这次潜水拥有80s好条件,80华氏度的气温,80华氏度的水温和80英尺的能见度。在潜点附近流有点大,Cliff和Angie同意躲在珊瑚礁之间,并在船的附近。Angie把相机调成微距模式,这样就不需要在珊瑚礁里来回游了。

    事故

    Cliff看到Angie安置好相机,准备拍摄小鲇鱼,Cliff决定探索这片珊瑚礁,寻找Angie的下一个主题。他知道她希望能拍到一只小丑鱼在海葵上的照片。

    从一个珊瑚礁到另外一个珊瑚礁,暴露自己在大流之中,他顶着流往回踢,这样他不会被流带走。

    当Cliff已经游到珊瑚礁边上,突然他右脚抽筋,当他想伸直脚舒展抽筋时,他被流吹跑了,意识到不对劲,他想边舒展,边顶着流游,可是进展的并不顺利,他被流吹的离Angie更远了。

    Angie拍完照片,抬头寻找Cliff,看到他正在挣扎并被流吹着走。她把相机挂在BC上,向Cliff的方向游去,Cliff试图用自己的双手解除抽筋。Angie意识到他需要什么,抓住他的脚蹼,示意他伸出腿,放松下来,顺着流漂。过了一会儿,抽筋解除了,Cliff可以游动了。

    环顾四周,他们意识到他们已经离潜点太远了,无法返回。他们同意升水,往船的方向上游去。Cliff在水面上充气信号棒,并向船上的船员表示,他们都OK。船员们一直关注着他们等接上所有潜水员后,再接Angie和Cliff。

    分析

    通常情况下,水下摄影师只会关注到眼前所要拍的东西,所以他们的潜伴感觉就像在独自潜水一样。在Cliff和Angie的案例中,他们对自己在潜水的角色有所了解。尽管如此,Cliff就像是没有潜伴的潜水一样。没有人注意到他,也没有人在紧急情况下帮助他。

    一个小问题,比如腿抽筋,会迅速升级成一个更大的问题。在本专栏中,我们已经讨论过很多次小的触发会导致恐慌和严重的事故。当一个潜水员感到不舒服或者没有准备好潜水时,他所需要的只是一个很小的事件,因为知觉的收缩伴随着恐慌而引发连锁反应。

    在Cliff的例子中,他在要潜水的早上感觉不舒服,他的身体有点脱水。他们已经有一段时间没有潜水了,所以他不习惯戴脚蹼。这些因素可能导致他的腿部抽筋。他自救,并得到了控制,但他却离Angie很远。

    Cliff很聪明,当他离Angie有点距离的时候,他顶着流游,确保他能游回到她的身边,但他并没有想到会突然抽筋。当他试图缓解不适的时候,他被流吹跑了。

    这次潜水事件相对于来说较小,而且并不罕见。轻微的突发状况,如面镜进水或抽筋,每天都在水中发生。通常,潜水员对这个问题的反应决定了它是一个被迅速遗忘的小问题还是潜在的灾难。

    在Cliff的案例中,如果Angie没有看到他被流吹跑,并对他进行了帮助,如果他没有保持冷静,他可能恐慌,快速上升。在恐慌的情况下,你很容易忘记你所接受过的训练,忘记在上升时吐气。这并不是第一次像抽筋这样小的的事情,最后导致空气栓塞的灾难。

    生命的教训

    1. 做好支援你潜伴的准备
      即使你这次潜水有任务,但也不要忘记你的潜伴。或者,你的潜伴应该接受独行侠训练,并准备好自救。
    2. 经常练习自救技巧
      潜水员在学习完开放水域潜水员课程后,就不再练习你学所过的技巧。在你的下一个安全停留时,你可以尝试脱带面镜,并练习缓解抽筋。这对你很有帮助。
    3. 与你的潜伴一起练习你所学过的技巧

      例如使用备用气源

    4. 如果你没有准备好,不要潜水

      没有潜水员想让你的潜伴失望,但是如果你没有在精神上和身体上准备好,就不要潜水。宁可错过一次潜水,也不要回不来。

    5. 不要忘记呼吸

      不要忘记在上升过程中吐气

    SWEPT AWAY

    Separation from a photographer buddy gets a scuba diver into real trouble.

    Angie slowed her breathing while she hovered just above the reef. She attempted to make herself invisible in the water so the tiny blenny fish would reappear. She really wanted a close-up of it coming out of its hole.

    Finally, Angie was rewarded with the perfect shot. She took three frames before the blenny disappeared back inside, startled by the flash from Angie’s underwater strobes. Moving away from the reef, Angie looked around for her dive buddy, Cliff.

     

    THE DIVERS

    Cliff and Angie had been scuba diving together for years. They had a routine. Angie was an avid underwater photographer, but Cliff liked to hang out in the water and enjoy the scenery. He had a sixth sense for finding small critters in the reef, so he often searched for Angie’s next subject while she worked with her camera. Cliff never moved too far from Angie; neither one of them liked to be a bad dive buddy. They made a good team, supporting each other in the water. They were both in their 40s and in good health.

    On the morning of the dive, Cliff wasn’t feeling 100 percent, but he wasn’t about to let that get in the way of making the dives. They hadn’t had a chance to dive in a while, and he didn’t want to disappoint Angie. He skipped breakfast, hoping his stomach would settle down.

     

    THE DIVE

    Conditions were nearly perfect for the planned dives from a small charter boat. The charter specialized in small groups — no more than six divers at a time — and that’s exactly the way Angie and Cliff liked it. It minimized the chances another scuba diver would disturb Angie’s photos or damage her camera.

    The dives promised the rule of 80s: 80-degree air, 80-degree water and 80 feet of visibility. There was a strong current on the bottom, moving diagonally across the dive site, but Cliff and Angie agreed they would hide in between coral formations and stay near the boat. Angie was after small critter photos, setting up her camera for macro photography, so there was no need to swim away from the reef.

     

    THE ACCIDENT

    After watching Angie set up her shot and move into position to photograph the blenny, Cliff decided to explore the reef and look for Angie’s next subject. He knew she was hoping to get a photo of a clownfish on an anemone for her portfolio.

    Finning from one coral formation to the next, Cliff moved out from behind the protection of the reef, exposing himself to the strong current. He swam against the current so he wouldn’t be carried away from the dive site, working hard to move to the next outcropping.

    Cliff was nearly to the next coral formation when he got a cramp in his left leg. When he turned to stretch it out, the current caught him and pulled him away from the reef and out toward the sand. Realizing what was happening, he struggled to stretch his calf and swim at the same time. Neither worked well, and he floated farther away from Angie and the original dive site.

    Angie finished taking her photos and looked up and around to find Cliff — just in time to see him struggling as he floated away. She clipped off her camera to her BC and swam toward him. Cliff was attempting to self-rescue and swim with his hands. Angie realized what he needed and grabbed his fin while supporting his ankle, stretching out his leg. She signaled to him that he needed to relax and just float. In a few moments, the cramp relaxed and Cliff could swim again.

    Looking around, the scuba divers realized they had floated too far away from the dive site to make it back. They agreed to surface, swimming in the direction of the boat while they did. On the surface, Cliff deployed his surface marker buoy and signaled to the boat crew that they were both OK. The crew kept an eye on the dive buddies while they recovered the remaining divers, and then moved to pick up Angie and Cliff.

     

    ANALYSIS

    Often, underwater photographers get so absorbed in what they are doing, their dive buddies feel as if they are diving alone. In Cliff and Angie’s case, they had an understanding about their respective roles on the dive. Despite that, Cliff really didn’t have a buddy on the dive. No one was keeping an eye on him or ready to help him out in an emergency.

    A small issue, such as a leg cramp, can quickly escalate into a larger problem. We have discussed many times in this column how a small trigger can lead to panic and a serious accident. When a diver is uncomfortable or unprepared for a dive, all it takes is a small incident for the perceptual narrowing that comes with panic to set off a chain reaction.

    In Cliff’s case, he wasn’t feeling well and was mildly dehydrated on the morning of the dive. They hadn’t been scuba diving in a while, so he wasn’t used to wearing fins. Those factors likely led to his leg cramp. He began the process of a self-rescue and was under control, but he was floating away from Angie.

    Cliff was smart and swam into the current when he moved away from Angie initially, ensuring that he would be able to make it back to her, but he hadn’t planned on the cramp. While trying to relieve the discomfort, he drifted away from the coral formations and directly into the flow.

    This dive incident is relatively minor, and not uncommon. Slight complications, such as an accidental mask flood or cramp, happen every day in the water. It is always the diver’s response to the problem that determines whether it is a quickly forgotten minor inconvenience or a potential disaster.

    In Cliff’s case, had Angie not seen him floating away and responded to give him aid, and had he not remained calm, he could have easily panicked and bolted to the surface. In a panic situation, it is easy to forget your training and neglect to exhale on ascent. It would not be the first time something as simple as a cramp led to a series of events that ended with an air embolism.

     

    Lessons For Life

    1) HAVE A PLAN TO SUPPORT YOUR BUDDY Even if you have a task on a dive, don’t forget about your buddy. Alternatively, your buddy should seek training in solo diving and be prepared to be completely self-sufficient.

    2) PRACTICE SELF-RESCUE SKILLS Too often, divers learn skills in their open-water courses but never practice them again. During your next safety stop, remove and replace your mask, and practice relieving a cramp. It will serve you well.

    3) PRACTICE BUDDY-RESCUE SKILLS See above, but the next time, practice air-sharing drills.

    4) DON’T DIVE IF YOU AREN’T PREPARED No diver wants to disappoint a dive buddy by backing out of a dive, but don’t dive if you aren’t mentally and physically prepared for it. It is better to miss a dive than it is not to come back from one.

    5) DON’T FORGET TO BREATHE Always maintain an open airway on an ascent.
