    There's a thread on here somewhere too, plus an editorial by Phil Short in an online publication.

    Or invest in an O Dive and sit tight til the bubbles go!
    O dive
    I didn't have much interest in it . But had a read up on it . Interesting quot from a well know cave instructor Phil S . Peeked my interest tho .

    Some might even use its predictive technology to see how far they could push the limits. . Maybe worth the investment lol

    Ps
    Probably a fun little tool to use between a group of dive m8. Worst bubbler of the week gets the drinks in .

    dive serlebs just jumping on the gravy train. Just end up with the same credibility as a 2 doller hooker. Katie price of the diving world. PT and PS have for some years jumped from one new thing to a nother I wonder why .
    All have been the best thing since sliced bread and a new course being written as we speak.

Rob is keen for me to sit around on the beach for half an hour before climbing back up the cliff, but I think I'd get very cold. Any other suggestions please?
    I had a spinal bend in July and have been diagnosed with a large PFO by Dr Mark Turner at Bristol. His recommendation was:
    1-Consider transcatheter PFO closure.
    2-Consider advice to be found at UKDMC.org on diving with a PFO - depth restriction of 15m equivalent air depth, use nitrox on air plans, one dive per day and avoiding heavy lifting and straining after surfacing (for 3 hours).
    3-Consider giving up diving.

    The link to the UKDMC statement is: https://www.ukdmc.org/medical-condit...foramen-ovale/

    In recommendation 2, the limits of depth, time and nitrogen all help reduce the possibility of bubbles forming (if there are no bubbles, then they can't shunt across the PFO). Limiting straining afterwards reduces the chance of any shunt ocurring (some PFOs only open when strained)

    The full recommendation in option 2 is statement 5 in the UKDMC document.

    I had a vestibular bend due to a PFO a few years ago. I wrote it up here:
    https://www.thediveforum.com/showthr...wc-gets-a-bend

    I kept diving. My diving doctor gave me a 15m EAD limit, which I kept to. I'd use nitrox where possible, and try to avoid exercise for a couple of hours post dive. I had the PFO fixed in 2020, so I am back to full diving.

    (The PFO constraints were:
    * 15m EAD limit
    * 1 dive a day
    * 1 hour maximum
    * No deco, although this felt a bit redundant given the other constraints.)

    As others have said, speaking to a diving doctor is probably a good idea - I would assume the amount of bubbling after a shallow dive would be minimal, but I am a random guy on the internet (who doesn't do much shore diving).

    Supposedly bad, do any post dive exercise straight after the dive, ideally first two minutes, if you are going to sit around resting then you need to do it for 90 to 120 minutes.. Have a look in Mark Powell's book deco for divers for the explanation/graphic but TBH it wasn't based on a long, large sample experiment.
