I was wondering if some people would post their method for breathing up. I guess I would like to hear about everything from when you break the surface on you last dive to when you take your last breath before descending on your next dive. Thanks
 
Hi Seahunter,

There are an almost unlimited number of breathup routines. Here's mine, used diving in warm, clear water. Begin a slow exhale as I approach the surface. If it is a long dive, 3 hook breaths, three more fast and deep, then slowing down until I can go into a fast in (1 sec) hold 5, slow out (10 to 20+). Once I am comfortable at 20+, I'm ready to dive again. Figure the surface interval at about double the dive time, less if shallow, more if deep. Short dives will have fewer than 6 recovery breaths. This is an adaptation of things I learned in a PF clinic. Works for me.

Good luck finding your own pattern.

My breathup has changed quite a few times and will probably change again.
I'm doing serial recreational diving. (I would probably do something different if I was doing competitive freediving)
I try to not control my breathing, as in to let it be close to normal tidal volume (though I'm submerged in water and try to compensate so it isn't accurate). If I am moving or feel exerted I will probably breath either deeper or faster.
About 60-30 seconds before dive time I will make a full exhale, full inhale, moderate exhale and then keep breathing normally, I do this to reduce heartrate change from my last breath which is also a full exhale and then a full inhale.
Except for experimenting purposes I don't reinhale the air from the mask.
When I surface I am usually calm, I exhale calmly a certain amount of air, maybe till my lungs are 60% full (I also lost air for equalization). I inhale calmly, not till I'm full. Wait 1-2 seconds and repeat a few times, maybe with a larger volume.
I will then rest on the surface for about double my dive time unless I dove deeper than 25m or FRC and then I might improvise.
I try to keep movement to minimum while I am doing my breathing, especially in the last minute or 2.
That's about it I think.
 
I am diving in 50 F water. I usually dive about 40-60 feet deep.

I had not heard of purging or saturating until recently. Are there other techniques like those?
 
it is often said that 'recovery time' after a dive should be (quite) a lot longer than the dive time. I reckon my individual dives last around 1 minute - occationally up to 1:20-30. Breathing up inbetween is not much longer.. Do I really need more time to restore Oxygen in my body?

i am diving for fun. i am almost always spearfishing. i don't know if that answers your question.
My idea is you have to find out what works for you best! try all(not inc HV)..find out the right one!.. use all the time same relaxing/breathing technics before dive(important!).....minumum 2min rest after each dive or more till you feel you relaxed!
the more you help your brain the more your brain helps you .all the best, sedate

Opps, forgot purging. 15-20 seconds before the next dive, I do 4 or so deep breaths to purge off some co2, take one last big one and go, suck a little out of the snorkel on the way down.

Why is purging OK, but hyperventilation caused shallow water blackout. They sound pretty similar to me. You are trying to blow off CO2 either way right?
 
Its all a matter of degree and an area where DBers can have some fabulous arguments. Imho little can be good, but a lot can kill you(hyperventilation and arguments). In my case, predive breathing rate is slower than my "base" rate, so the blood co2 level is relatively high. A few purge breathes knocks down the c02 but not near as much as huffing and puffing until the cerebral arteries constrict and dizzyness or tingling set in.

i do a slow release from about 6 feet below the surface (when im diving in water more than 20 feet) then i do a hook breath, hold it for about 5-10 seconds so that my body relaxes (i find this helps get rid of the fatigued feeling i get) then i do normal breathing for between 30 seconds and a minute, then begin to take deep breaths, holding for about 5 seconds at the peak, exhaling fully, then take a nice deep breath and head back down.

all of my diving is done in warm water, and, if ive done a longer than usual dive, i will remain at the surface longer, my dives average between 40 seconds to 1:30, and if i am doing an aspetto, maybe 1:30 - 2.. no watch so i cant honestly say.
 
seahunter,

as you say lowering co2 increases risk of swbo. dive only when you are very relaxed and properly recovered from the last dive. to ventilate your lungs without blowing off co2 breathe very slowly and deeply (no max inhales as that is too strenuous and will increase heartrate). 2-3 breaths a minute would sound all right to me. the time on the surface will depend on how fast you recover.

try to be as consistent with your diving as possible.
