Hi Guys, what a great forum.....
I am sitting at the computer hooked up to a pulse oximeter that I normally hook up to the dogs and cats I operate on at my vet hospital.....I am a 52 year old , pretty good shape, windsurfer, snowboarder and soon to be freediver/spearfisher. I just got back from meeting Manny Puig in Florida and hope to go Gator swimming in the 'Glades some time next year....the carrot for Manny will be that I own a shark cage and get regular swims with Tiger sharks here in the summer! Having watched him lifting 400# Groupers and 10 foot Gators makes me realise that I need to work on my breathold skills.
My resting heart rate is 66 bpm, goes down to 52 when I'm super relaxed and off the caffeine. On a static just now my Sp 0 2 started at 98%, my heart rate went up to 100 and at 2 mins I still had a 96% Sp O 2 . It then fell fairly steadily over the next 2 minutes and I quit at 4 minutes with an Sp O 2
of 75%.......I took a series of deep breaths(!) during which my Sp O 2 FELL FURTHER to 68% prior to climbing rapidly back to 99%.
I AM AMAZED.......If one of my patients dropped below 80% I'd be panicking
......but I guess they are on O 2 and anaesthetic so any decline means some serious perfusion problem if they're still breathing......
At what level of Sp 0 2 am I likely to lose consciousness and from these results can any of you predict how long I can look to aim for when Spearfishing? We are limited to the use of polespears, but we have Black Groupers here that run to 125# plus and can be found in 20- 50 feet of water. I hope to take a big one on Manny's new spear with a slip tip and
detachable floating rope setup but I'm sure that some major wrestling is going to be required!!
Looking forward to further discussions on this fascinating site!
