What if you run out of air while scuba diving??

Back when I started diving buddy breathing was normal. Octo's were just a suggestion not the norm. Buddy breathing is not really that hard until you try doing it with a panicked diver that refuses to give it back. :) Also, even fewer know how to buddy breath with a FFM.

I played subnautica I'm automatically a pro 😎

You are amazing Sara and so funny...regards from Argentina

Deal with it before it seems stressful; great advice for anything diving-related. Just for interest, many years ago I did the submarine escape course. This started in a chamber at the bottom of a 100 foot tower filled with water. We waited while the chamber was flooded and the hatch opened and then had to swim up that 30m, with no kit. The instructor said "just breath out as fast as you can". It was true! With four times the air in your lungs than you would need at the surface you really couldn't get rid of it fast enough. We all wanted to go again, and again! So newbie divers can be confident that ascending from 10m without a breath really is not a big deal, and far easier than simulating it horizontally in a pool as per PADI.
I've only once had someone (nearly) run out of air and that was, ironically, on a Rescue course. I was at about 12m playing an unconscious victim and the students had done a fair bit of work on search patterns and lift practice before they came across me. The guy who lifted me was absolutely frantic to get to the surface and when we got out he confessed his SPG was on zero. He had been so tied up in the training that he'd not been checking, and of course he'd been working very hard. He finally did check his gauge as he got to me and everything suddenly got urgent. But the Human Factors point is that he was so engrossed in his role as rescuer that he never considered he might be a victim. I still had 130 Bar and could easily have given him some if he'd made me aware, but it never occurred to him that I could help. Moral: always know how much gas you have and that a) task focus such a photography, fish, turtles can completely distract you; b) swimming against a current, or lots of depth changes as you explore the reef/wreck etc will make you use more.
Last point on COVID and relative risk: if someone asks me for air, for real, I'm not going to turn them away in case they or I have COVID. Death from COVID, 3% if you're infected, less than 1% in the general population. Death from drowning, pretty near certain. So no need to share regs for practice right now, but you shouldn't think twice if it's for real.

This video will probably save lives

can i learn EBA on openwater course?

At last a scuba channel that made the whole Air Supply reference.

Great video. I was told many many years ago, during a low on air ascend..... you can all ways get a couple of breaths of air out of your BCD instead of dumping the air .

3 years ago when we are scuba diving on boracay I freaked out underwater because I cant go up the surface and I ran out of air

Sharing air and still diving? Wow... crazy... great video thank you.

It would be great if you could explain to people why you must not hold your breath during scuba diving. I see than people don't understand why. And instructor never explain why.
And also why you can't give air to a free diver.

A free diver is holding is breath from the surface, so when he descend deep underwater, the pressure of the water is squeezing the larynx because the air is not equalize. (Your lung get tiny for the same reason).
A scuba diver is breathing air as he descend so the air in his lung are always equalise, making him able to breath with a lot of water pressure. So the free diver will not be able to breath your air because the larynx is closed and with the difference of pressure, you will not be able to open it.

Sarah have you ever had anybody splash in off of your boat and they forgot to turn on their air? I'll bet that happens.

I watch your videos when I miss diving :(

Great, I reviewed the CESA again.

I really just wanna know what happens if you run out of air.. Does your ability to take a breath just stop. Or are you still able to take a breath but the oxygen content is just super low, thus making you hypoxic before you go.

The latter being the best scenario when this happens i'd think. least painful.

I've found that literally the best thing you can have is great training. But you should see the video of the worst scuba instructor ever. He rips there weights off, goggles off and shuts their tanks off. Scary.

You messed up your dive pretty good.. Not looking at your air supply.. Hope your buddy has air.. Otherwise 1 way to go up and breath out

You do a controlled ascend. As you rise to the surface the air in your lungs expands.

Luv the way u explain things u r so hot ! Im
About to do my open water certification this week-end in cold Québec water lake …. Thank u 4 your tips i wish you where this week-end to calm

Down

They teach to dump weight when out of air below 9 meters now? That seems dangerous to me, and not warranted. Normally a first stage will stay open when below its set intermediate pressure and not regulate anymore. So when you're out of air, you're not really out of air, it's just that the pressure in your tank is too low to combat the ambient pressure at the depth you're currently at. That means that making a controlled ascent you should get a few usable breath as you're going up and the ambient pressure drop, not enough for a safety stop but surely enough to get a calm and in control diver to the surface from any depth.
Mind you that I learned on J type valves and no SPG, meaning that out of air situation was a regular thing and not something to panic with.

What happens you die love it I believed her for a sec

We also teach to first donate your primary regulator during out of air emergencies. (again covid complicates things)
Reason: we're cold water divers most days of the year, so we have each regulator on a separate first stage & separate valve.
It happens that people mess up, and not open both valves.
Or
Many people don't often use their second regulator under water (some never do).
So, by donating your primary, you offer an air supply that is working 100%.
....you take your second/long hose. And when your buddy has regained his breath,
you switch back to your primary, buddy takes the long hose, and you work on completing all your stops required to end the dive.

FANTASTIC AND BEAUTIFUL woman in the water fantastic and very very best 🆗✋💯💦

Please write me for how many minutes you have enough air under water with a 12-liter bottle, on average, of course.

I actually don't mind that diving sometimes appears "scary" or "dangerous" to the public, as it keeps many people who would probably be bad divers out of the sport.

Appreciate the safety tips!! Thank you

Thank you Sarah for sharing all techniques....

WOW

I think it would be great to have gas planning introduced in diver training to reduce the likelihood to end up in these situations. Make an estimate based on previous dives to determine how long you can dive and during the dive you only check your SPG to double check this, making it less likely to be surprised by the amount left in your tank. Make a calculation how much gas you need for a safe ascent with your buddy while sharing air and you're done. We all got the instructions what depth does to volumes in our open water class, it's not rocket science. My AOW instructor 10 years ago assured me in a 1 on 1 conversation that he had enough gas with him if I needed it. There was no need to make simple calculations to predict if a specific dive could be made safely. Last year during a discussion about a risk analysis course again instructors assured me that gas planning is not necessary as long as you stay within rec limits. All three of them however had no issues with teaching students how to respond in several ways to an Out Of Air scenario... I'm uncertain how to bring this up but I often feel ridiculed for doing so and l miss the bravado of the instructors to question their logic but I do want to add this point to your otherwise wonderful down to earth video. I like the way you discuss various subjects on your channel and though I may not agree on all of them I do enjoy watching them. I want to thank you for your honest answers in the replies here to your video's and I hope you can find a way to continue your passion underwater in these difficult times.

This actually happened to me during advanced diver deep dive training. The air guage on my gear was 400 psi off. We were ascending at about 80 ft. when I hit empty. Remembering my dive training, I calmly swam to my instructor, pulled his octopus regulator, had a brief hand signal conversation, and ascended to the submerged tank for the safety stop. I didn't think it was a real big deal. Everyone else did, and in hindsight, it was. That's why we train. I did learn to conserve air better, and be willing to end a dive early due to low air. Question: Doesn't every open water class practice buddy breathing?
Sorry for the long post!

the scubadiving is safer than mma

Very informative video. Thanks

Thank you. Very knowledgeable. Thank you

and IF they still sold SCUBA tanks with the good ole J value , you would still have 300 psi - just in case of you "running out of air " ! the dive shop near me will charge you for a visual inspection if you show up with your empty tank $ .

New to diving loved this video

Thank you i’m learning so much from your channel.

Going through emergency situations in my head I come up with one idea. In case of last resort, when you can't breathe, do you think it would be possible to take a breath from BCD? Assuming it is not empty, also during ascent it will be expanding. For sure it would be safer to do CESA from 10m, but what if you are at 30m and things went really wrong?

One thing that you should say is that almost and I say almost you run out of air on the exhale. You have inhaled a breath and after exhaling you go to inhale and there is nothing.

When I got certified, 30 years a go, we were trained on the shared air technique because almost nobody had an octopus (octopus and BCDs were a luxury, not an standard)

I check that gauge every 5 mins 😂

Honestly, running out of air scares me a lot less than getting an IBS attack at depth. At least there's solutions to running out of air. The latter doesn't have any... ahem, solutions. At least I'm not the only one with that fear - before my training dive, the instructors were joking (half serious) about not eating before the dive.

I want to do a dive trip with my local dive shop to one of those tropical islands, but my darn stomach. $2,000 for everything isn't bad.

Edward Norton story about Leo DiCaprio and him doing this is what brought me here.

Happened to me diving
I wad using resorts equipment
I was at 1200 and new I should surface three breaths later I was out
I shared air to the surface turned out had a faulty regulator it was very scary

Ever heard of gasplanning?

if that happens, you didnt learn anything.
find a new hobby.
diving requires safety

You should never run out of air.

looking at buddy* 😒 Here ... have a stage tank. Save yourself~~ 😉

I liked your video and the atmosphere of tropical waters. Excellent work.

Better to have separate regulators than an octopus and a spare tank, always
