- {[Never Hold Your Breath]} Robbie's Emergency Ascent
• {[Never Hold Your Brea...
The "Golden Rule" in scuba diving is, NEVER HOLD YOUR BREATH. In today's video, Instructor Trainer Bryan Stafford sits down with one of his best friends who had a panicked diver situation while underwater, and bolted to the surface while holding his breath. It is Lake Hickory Scuba Centers Inc.'s goal for all divers to constantly learn and grow as divers. Even if the lessons you learn come from our mistakes.

Thanks, Brian and Robbie,
I felt like I was the only one who had been through this, and I am an instructor with SSI. Two years ago, on of all days, my birthday, I had a very similar situation in an open water class. I had a student panic and tried to bolt to the surface from 35'. I maintained contact with the student to prevent them from bolting, and in the process, my breathing became labored due to their struggle. After getting the student to the surface safely, I noticed breathing had become difficult and began gasping for breaths. What also did not help was that it was a very high pollen season. After getting back to land I was still very labored with breathing and had redness in my spit (not a good sign)..So, not to panic the students, I said it was asthma acting up.
Later in the day, I was exhausted, and I could hear gurgling in my lungs in bed that night. THE MOST IMPORTANT THING I did was call DAN (Divers Alert Network) in the am, and they asked all the questions from start to finish and said there was no reason to panic. You were only at 35' but to call the doctor when they open and get in for a lung x-ray, EKG etc. After all that the doctors found nothing with all the tests they ran. All I had in my head when the crap hit the fan was STOP. BREATH, THINK, and ACT!. Training pays off when you can keep your head on straight. There is a saying that goes like this: " The Cleanliness of Theory is No Match for the Mess of Reality!". Unless someone has been here, all the theory in the world won't help if you can not apply it. Train, Train, Train!
Love your channel, Brian, and keep on keeping on Robbie! Nothing to be ashamed of; you now have the experience to prevent it from happening to someone else.
Absolutely thank you for sharing your story with me
Glad you liked the video @1Sulster. Sounds like you handled the situation in the proper manner. Glad to hear that your student was ok, and that you were ok as well. One great thing about diving at shallower depths, with in the first atmosphere, decompression sickness is rarely an issue, however, embolisms are a major concern as they are on all dives. Stop, Think, and Act will always apply to any stressful situation.
Your reaction video is awesome and much appreciated. Please make more like this. You just took a mistake (or several) and turned it into a golden opportunity for teaching and learning, and not silly dramatic reactions like others. This is exactly what a reaction video should look like- essentially you did a debriefing, but in a format where we can all learn from it. Thank you!!
Robbie, you’re not stupid, please don’t say that. You are human and you made a mistake. Thankfully you did not get hurt! And thank you for being vulnerable and sharing this with us so we can all learn. You’ll make a great instructor.
One more thing I’d like to add. If there is any significant gap between dives, please take a refresher course. It may seem silly but it’s not, these skills keep us alive and it’s vital that they be second nature. Even the skills to dive can task load us, never mind keeping up with the group, watching fish, or anything else. We need to be proficient at our skills- refreshers are essential after gaps.
Hello @SummersideDiver. We really have no intentions of doing reaction videos to other divers videos. However, any incident that we were directly involved with, where we have first hand knowledge and not making an educated assumption, we will definitely be making more.
@@LakeHickoryScuba that is perfect. Your channel is amazing as is, thank you for sharing your experience and knowledge.
Thank y'all for posting this.
I Have been following and going through Gareth Lock's Human diver. This is exactly what it boils down too. Create an environment where we can talk about this stuff.
This is a great example of what Gareth reaches in his course.
Glad you liked the video @bubbasmith9432. We hope this video helps others to understand the importance of training and experience, and how they correlate to diver safety.
Thanks guys for the comments and the confidence booster but I know I made a mistake and I am human and will probably continue to make a few more mistakes in my lifetime but yes, that is one mistake. I will never make again I can assure that yes I am monitoring this video for any anybody that has any questions from my end of the retrospect
Glad you're here to keep making mistakes! You aren't dead and that means you get a chance to improve! Thanks for sharing.
It's so refreshing to hear someone discussing something that went wrong. So often people are embarrassed or ashamed or it hurts their ego or whatever. This way we can all learn. Thank you. This highlights the importance of staying current with skills and refreshing if there's been a gap. I've met someone who said they'd been drysuit certified 10 years. When did they last dive a drysuit? Ten years ago! And you are absolutely right about consolidating after a course and gaining experience before taking another. Then you'll be safer and get more from the more advanced tuition. Anyway, thank you again for sharing.
Glad you liked the video @timgosling6189. We hope others can learn from this video as well.
@@LakeHickoryScuba Always useful stuff.
most important your safe and sound. Will all learn from this. No shame. Be safe.
Glad you liked the video @TS-hz4lx. We hope others can learn from this video as well.
Thank you for sharing ❤
Glad you liked the video @rey_nevan. We hope others can learn from this video as well.
To let you guys know I have now made several pool dives and open water dives in the same gear I was in on this video and no panicking I have also taken the stress and rescue course to help out myself in check and can so I could recognize stress and panic and other divers to help me be a better diver
If you read the accident reports (DAN/BSAC), around 25% of fatalities are from divers holding their breath, and the subsequent pressure injuries. That's one-quarter that break the number one rule of scuba diving.
Hello @toadou8127, just imagine the number of accidents that are not reported to DAN. I would venture to say the percentage is much higher.
It's a good thing you didn't swallow at 15ft or continue to prevent your lungs from offgassing. at 55ft there is an absolute pressure of 2.7atm, at 15ft we have 1.5atm. A "normal" maximum amount of air the lungs can hold is about 6L or 360 in^3. So, let's say that at 15feet you had maximum inspiration: P1V1 = P2V2, so (1.5)(360) = (2.7)(V2), meaning V2 = 200 in^3, that is 55.5% of your lung capacity. So in theory (DO NOT DO THIS) if at 55ft you had only filled 55% of your lung capacity, then your lungs would be at 100% capacity if you ascended to 15ft. If you continued to breathhold for 3 more feet it would be 110% of your lung capacity which smells of bursting components. I'm glad you're okay because this is a harsh risk you've undergone here! As your dive instructor was saying, the feeling of not getting enough air could have been caused by a CO2 buildup by not breathing out enough, so your lungs could have been filled to 55% at the start of your ascent, even if it felt like 20%. To summarize, an ascent from 55ft to 15ft multiplies gas volumes by 1.8. He might not have even exhaled on purpose, but during his ascent, his epiglottis was relaxed and therefore allowed for the lungs to forcibly offgas out your mouth once reached 100% volume.. That would make swallowing during the breathheld ascent extremely dangerous (potentially fatal) as during the entire duration of your swallow your lungs cannot offgas at all and your rate of ascent being over 2ft/s means that at a shallow depth as I showed above you could have a 10% increase past your lung capacity in just 1.5s which is about how long a swallow might be. In my mind you are lucky to be alive, because an overexpansion of the lung would move your heart, possibly restricting its passageways or other fatal consequences. Could it be your suit squeeze is what prevented you from filling your lungs to 80% with air, because 80% filled lungs at 55ft ascending to 15ft on a breath hold (due to epiglottis blocking) would be guaranteed by the numbers to present immediate acute possibly fatal symptoms. Either way man I'm really glad you're still here with us - this was a close call and it serves as another reminder just how important considering overexpansion injuries are to divers. We mostly worry about the dissolving of nitrogen in our tissues at depth over time, but overexpansion can equally kill you depending on an emergency happening just a minute into your dive. Stay safe out there and I appreciate the reminder to the diving community how important it is to operate appropriately when we engineer these situations where we are breathing compressed air or other gas underwater at depth. Our natural urges like breathhold and ascend must be oppressed because we are breathing compressed air, and that's why training and practicing your training is so important in these situations - to overwrite our natural instinct which can get us killed for it. There's a lot of risks and your life were awfully exposed to this one. Cheers and happy safe diving in the future to you. PS - This is also why scuba units NEVER give a breath of compressed air to a freediver at depth, because they might hold that air and overexpand on the way up and pass away due to it leaving YOU responsible.
Thank you for sharing @snared_, Boyle's Law is no joke during ascents and descents. Robbie was very lucky during this dive. Whether it was a simple suit squeeze, CO2 retention, or nerves, its always important that we control stress and never let it get to the point of panic as he did. As he stated to another commenter, he has made several dives since then and his confidence has gotten better. As he continues to grow as a diver, his ability to compensate for additional stressors will become easier for him. As we tell all divers, practice, practice, practice.
Robbie don't get down on yourself about having a normal human reaction. Guaranteed you won't ever do this again you will recognize the signs and how you feel uncomfortable much earlier and wil be able to take a break to sort things out before they get this far. Your situation was similar to one I had early in my diving career, but I didn't know what hypercapnia was or how to recognise its onset. I had a uncontrolled acent from about 20 ft and almost blacked out. I was overweighted and overexerting myself and not breathing full breaths. After getting some information I realised my reaction was Physiological not Psychological. I am able to recognize the onset of it now and I know that if I take a break for a couple of minutes to offgass the extra CO2 i will feel better and can continue the dive. Thanks for sharing your story.
I was in my training when the person in front of me got their airline caught on something while we were about 50 ft down, they started to panic, and nearly pulled their tank off, I was able to unhook their line and calm them down. Stay calm.
Great job on assisting the other diver @stevem1081. This is another reason we encourage divers to take the Rescue Diver program. Not only does it build up confidence in themselves, it teaches them how to control stress and how to handle stressful situations.
Humm! If you are humming, you can't hold your breath!
This is very true @MAGAisacult. Thanks for sharing.
Is the quarry still closed. Did they get the zebra muscle problem solved?
Yes it is still closed
They are working on it
Hello @ncbuckslayer8244. Unfortunately, the Lake Norman Quarry is still closed to the membership. Hopefully it will be opening back in the near future.
I just lost my Comercial license because I held my breath for a fraction of a second well emergency accent. Like 2 months ago. Got the big old pop. Be carefully everyone
Hello @nyax129, thank you for sharing your story with us. We are truly sorry to hear that you commercial licenses have come to an end, but we are glad to hear that you are still here with us to talk about it.
