I was diving on our last open water test and we did a few things like flood the mask and etc and make the ahhh sound and etc. Right after that the Dive master waved for us to follow him. I was in a group of 6 but the visibility was very poor I could could barley see the guys fins in front of me. I did something dumb I check to see how far we were under it said 48' but I did not look at my Air pressure. I could feel the air getting harder to breath and I panic.
I assume that your skills were done in shallow water, and that they did not take overly long. This is purely conjecture, but there is a good chance that you had plenty of air, only you failed to open your tank valve fully (less 1/4 turn). If this is the case, your dive buddy failed to check your tank valve and/or you did not inhale sharply on the reg while looking for a pressure fluctuation on your SPG. As you descended you required larger volumes of air (relative to STP) to fill your lungs - your regulator could not deliver the air at that rate (since the tank was not fully open) and you found it hard to breathe.
I started swimming as fast I could to the surface hoping I was going to make it.
At this point you could still breathe, albeit with difficulty, and you bolted to the surface in an uncontrolled manner. I am a novice diver, but even I know that this is a very bad idea and points to a lack of training and discomfort in the water. Were you trained properly and failed to follow those lessons, or was your training lacking?
With respect to comfort in the water, in a multi-week OW cert course you would have had lots of pool training and time to get comfortable in the water. Did you do a proper OW course, or a weekend special? In my OW course we were required to swim the length of the pool (underwater) on a single breath wearing only our trunks and our fins. The swim terminated at the deep end where,
without surfacing, we had to locate our personal gear (and not someone else's), turn on the tank, start breathing, and don our gear. The value in this training is that, at the end of the swim, human nature is to pop up to the surface. Instead, we were required to swim down and follow a procedure. This does wonders for your confidence in being able to resolve a problem and therefore
avoid panic. Just swimming pool lengths underwater on a breath of air might help your confidence in the water. Swimming skills should not be under-valued when it comes to their calming effect on a diver.
Edit: One great lesson learned from a distance swim underwater is that you find out quickly that the key to traveling a distance on one breath is
not to start swimming as fast as you can, but to swim steadily and deliberately.
I spit out my regulator about 15th, sucked in water and somehow I still managed to make it to the top.
Were you trained to do this? Even if you ran out of air at 58 ft, your tank will deliver gas at 15 ft as the pressure on your body drops.
I was going to dive today to get past fear but my lungs hurt like someone took a hammer to them. I am guessing it's because of me holding my breath.
Read TSandM's response to your post - you need to see a physician before you dive.
At very least, contact DAN (
DAN Divers Alert Network) using the DAN Emergency Hotline: +1-919-684-9111 . They will likely advise you to see a physician ASAP.
