Video request by, "OneWorld"
"Could you please share the knowledge about 'Air Consumption' as me and my other diver friends also love to know the way... how could we save more air (especially with Nitrox) when we're diving. Best Regards."
Before I begin, I want to clarify that this video is about how much gas one uses during the entire dive... There are plenty of videos out there that tell you how to calculate SAC or RMV, or you can even use the calculator from my website. The link is in the description:
SAC/RMV CALCULATOR: https://jcaelitescuba.com/rmv-sac/calc.htm
Also, gas consumption with air, nitrox, trimix or other combination should not change the volume you consume throughout the dive.
While trimix is a little "colder" when breathing it in cold water, if you are using trimix as an inflation gas during a dive with a drysuit, consider a dedicated pony bottle with air, or if you want to spend the extra money, argon. Be sure to label the bottles appropriately. Argon is poisonous to breathe...
The first thing to do is to slow down! Really. When you are taking your time, you breathe less and that minimizes the fluctuations in those micro ascents and descents due to inhalations and exhalations...
The next thing to do is keep your eyes on the road... What that means is, know where you are going and don't spend a lot of time looking around before you get there. Look where you are going and make sure your dive buddy is still there. The more you move your head, the more the rest of your body will move...
here's the modified frog kick
as you can see, it takes very little effort and expends very little energy
If you're diving with a buddy, be sure that each of you are close. If you're spending part of your dive having to swim to get to each other, most divers usually kick faster than required at that time, and you're wasting gas...!!!
or even better, stop, and look around...
When you are ready to look at your instruments, be sure to only look at what you need... if you need to check your SPG, just check the SPG... for those that dive on air-inregrated / compass only integrated computers, pick only one detail to confirm
here's checking your SPG...

Notice how I didn't hold my breath when I looked. Many divers hold their breath when looking at their instruments
here I am dumping air from drysuit
slow, smooth, and with very little effort...
If you are going to wander around, you'll use more air. When doing your dive plan, plan for air consumption. If you used more, ask yourself why?
When approaching something you want to show others (the size of the Sunflower Starfish to my hand), get neutrally buoyant first, then approach the object, and then use your breath to adjust ascending or descending.
Breathing is important, but is should be smooth and regular... Look at the bubbles and how regular they are and the sizes they are.
When I'm diving, I'm in the zone...!!! Always the most relaxed and never in a hurry for the dive to end. If your dive is going to end too soon, plan for another dive...
18 seconds... 3 breaths...
1 breath every six seconds
10 breaths per minute = super relaxed
12-20 breaths per minute is usually normal
here's the other side...
If you have to or want to turn, learn to use your fins and perform the helicopter technique...
Lastly, be sure to get your weight right... you only need enough weight or ballast to decend at the beginning of your dive.
If you're in a drysuit, a couple extra pounds is okay, but if you're adding extra weight so you can add extra air, it will add up.
While some may disagree, if you're in a drysuit, only use your drysuit for buoyancy. When you have too much squeeze, it's not comfortable, and if you don't have any squeeze and still sinking, you're overweighted... After all, "Who's the barber, here!"
