Panic underwater!


This post is a bit more personal, I'm writing about a panic situation that I myself experienced. As all divers propably know, panic underwater is one of the most dangerous problems a diver is likely to come across.


Last June (2012) I did my PADI Rescue Diver certification. We were working on the open water rescue scenarios in relatively shallow water. As we were doing an underwater search scenario with two other divers, I noticed I had a slight buoancy problem. I was getting underbuoyant, and unable to control it with my bcd. This wasn't a big problem, though, as we were skimming the bottom anyway, searching for the ”missing diver” (that was in fact a thrash can lid that the instructor had thrown into the water.)

The visibility at the site was not very good, about 2-3 meters, quite ideal to make the search scenario a bit more challenging. And now that I was constantly pushing myself off the bottom, blowing up more debris at the same time, our visibility deteriorated even more. We had our work cut out just keep together, even though we were literally only an arm's length away from each other. This wasn't a big problem, though, since we all knew where we were going, doing a U-pattern search with compasses.

Eventually I found the cause of my buoancy problem. My inflator quick disconnect valve had come off my bcd. Maybe I had not connected it properly before the dive, I don't know. But it had come off, and it was causing me to sink to the bottom. So I thought to myself -calmly-, 'stop, breathe, think, act'. The thing is, if I stop, the others won't notice me being left behind because we had practically no visibility. So I didn't stop. That wasn't a big problem, though, since I did breathe and I did think, and we really were not deep at all, only about three or four meters max.

So I thought. And came up with a plan of action: I'd get the valve back on while on the move. But as my hands were working on the valve issue, they were no longer keeping me off the bottom. So I fell to the bottom, scattering a thick cloud of debris around me and slowing me down. I'd have to hurry up now to catch up with the others. This wasn't a big problem, though. I had my compass, so I knew which way to go. And the others would notice I wasn't in my place in the search line, so they'd wait for me.

So I stopped on the bottom to work on the valve and get it back in its place. The thing is, because the water was relatively cold, I had my neoprene gloves on. So I wasn't able to get the valve back in place. I couldn't take the gloves off, because my computer and compass were tied on my wrists, on top of the gloves. Now that WAS a big problem! I could-not-get-the-bloody-valve-back-in-place! SO stressful! I felt my breathing rate increase, my hands started to shake, I couldn't get enough air from my regulator, and still I just COULD NOT GET THE VALVE BACK ON! I was lost from my buddies in cold water, I had no visibility, no buoancy control, and -as I felt- I was running out of air! I felt overwhelming fear, and a strong urge to get rid of my regulator and just get to the surface as fast as possible.

Luckily my dive buddies found me. They were never far away in the first place, and they noticed I had a problem. So -as we had just learned on the rescue diver course- they assessed the situation, approached me from the front, made contact (looked me in the eyes and took my hand) to calm me down, and assisted me to the surface. There I was able to establish buoancy and calmed down again.

The situation was not supposed to be in any way dangerous. We were all relatively experienced divers. We were in shallow water, with the instructors watching over us from the surface. And we were so close to shore that I could literally have walked along the bottom to the beach. But, as I learned, it doesn't take much to make a situation feel dangerous and overwhelming. Even small, seemingly trivial problems can cause excessive stress underwater.

Looking back, there were many stress factors that contributed to my problem underwater: There was peer pressure, because I was the most experienced of the students doing the course. There was my own will to perform well at the tasks. There was also some physical strain from previous rescue scenarios. Put on top of that the conditions at the dive; the poor visibility, coldish water, and the difficult task that we were supposed to perform. And the little problem with my inflator quick disconnect. Pile enough seemingly trivial stress factors on top of each other, and they can overwhelm a diver. They say that the Rescue Diver course is one of the most challenging courses both physically and mentally, and for me, it really was. So far.

  1. I had a near panic situation just the other day (6 Aug). I'm a relatively new diver, I've only been diving since March though I've got just over 60 dives in (several deep dives up to 120 feet) and I'm two specialties away from my Padi Masterdiver (Other than your experience with the valve, how fun is the Rescue course! I loved it!). Anyway, the first dive we did the other day was to about 117 feet and about 50 miles off the coast of NC. There was a strong side current near the bottom. I was photographing/videoing my friends who were spear fishing and I had to work hard (first mistake) to try and catch up with one of them to get him on video. I stared breathing hard, and that deep, no matter how good a regulator you have, the Nitrox you're breathing pretty much turns into soup. My vision started going a little spotty. Of course in such situations your mind immediately starts thinking worst case scenarios; we were breathing Nitrox (28%) which I had analyzed and tagged myself, yet visions of what happened to Sheck Exley started dancing in my head and I started second guessing what I knew to be in my tank. What if there was too much O2? What if this was a warning of Oxygen toxicity? My heart started pounding and I looked up. Much too much water on top of me to see the boat. I wanted the surface, but then thought of what happens to a soda bottle when you first open it after it's been shaken and all the bubbles come spewing out. Funny enough by this point only a few seconds have gone by. I signaled my buddy that I was going to the anchor line and slowly started ascending, watching my computer to keep my ascent in the green. I got to 80 feet, 70, and stopped at 60. I watched the blue world around me and timed my breaths; four seconds in, four seconds out. My heart stopped pounding and I was able to focus on why it is I love getting in the water. I caught my breath and felt relief that none of my nightmares of what could've happened actually did happen; I didn't get oxygen toxicity, I didn't get bent, and I didn't let the panic take control of my mind and do something else stupid. I got a good couple lesson's out of it though. I now thoroughly understand why you don't push yourself underwater and I also now know what a person feels when panic gets a hold of them underwater. Knowing that will make the lessons I learned in the Rescue Diver Course much, much more effective since I now have experienced what a panicked diver is experiencing and that adds insight to why we're taught to do some of the things we do. Thanks for posting your blog, it's really great to hear other divers experiences in this subject (and also surprisingly good timing!). Thought you'd like to hear what happened to me so you could maybe use it to emphasize the lessons we get in the Rescue Course.

    1. Thank you for sharing your experience! This is another good example of how little it takes for panic to attack when you're underwater.

      Good on you for being able to keep control and act correctly, not letting panic take over. In my case it was my dive buddies who took control and prevented me from doing the stupid thing and jumping to the surface.

      I agree that the rescue diver course was great fun though it was challenging. And both out experiences show how really useful the course can be!
