Hypoxia testing for medical science - London

[turtle]

Hiya,

a friend of mine doing a phd in London is running some tests on the body's response to 'local' hypoxia, i.e. restricted bloodflow to a limb for example. It seems this prepares the whole of the body for hypoxia. Seems pretty cool & it has a major application to heart surgery, possibly very interesting for freedivers too.

He is looking for about 30 people to join in for 3 sessions, where under different conditions in a lab, he will take a small blood sample and test o2 levels. One of the sessions will require exercise to point of failure, but the other two are pretty sedate.

Anyone interested in helping out? May be paid as well, i will check. Thought i'd give a heads up in case any DBer's are interested once it goes ahead.

Otherwise, be interested to see if anyone has any thoughts on it... are you out there Seb? :martial

Cheers
Fred

Depending on what is involved, I may be interested.

You get pins and needles, then it goes numb, then when the sensations come back you have to run around shouting f*** that hurts.


Where do i go to get published?

Dr Wellard, haven,t you been involved in medical testing before? at least thats what I heard.

 

[turtle]

lol, no i think the idea is more that local hypoxia somehow prepares the whole body for hypoxia. It sounds interesting anyway & is being used experimentally in heart surgery already from what i understood.

 

[hyeparis]

before testing effect of hypoxia on different parts of human body, should not he first try limiting flow of oxygen in other species, such as chicken?

 

[turtle]

what, choking the chicken?

hehe, nice try.

for a non-native speaker, I did my best )

 

[BennyB]

what, choking the chicken?

You mean a scientist will us pay for that?????

This changes things...

Further to my last study i have found that if you have Hypoxia in the vicinity of your right arm, then choke the chicken it feels like someone else is doing it. It may have its uses.

Dr Wellard. PHD (feel free to make up your own words for the acronym)

I just re-read the original post and with the change in context i can now confirm this post is officially hijacked. LOL.

 

[turtle]

shoulda known that mentioning hypoxia on t'interweb was buying a one way ticket to porn. Expected better from DB tho... Alright, not really ;-) & no this thread ain't hijacked. Yet. Barely.

Will post more when get the details.

Are you going to give details impact of hypoxia on all parts of the body?

Ok, here goes. :martial Who wants to find out a bit more about hypoxia, save some lives & look cool puffing away on a treadmill in a lab?

I add, this is nothing to do with me, but I will be volunteering & would be cool to see a few other DBer's around for it. And no choking of poultry or any other wildlife :blackeye

Here is a copy of the blurb -

WE NEED YOU!

The Centre for Aviation, Space & Extreme Environmental (CASE) Medecine at UCL are looking to recruit volunteers for research into tissue hypoxia

CASE medecine is a group of clinicians & scientists with specialist interests and training in the medecine and physiology of extreme environments. Our flagship project is the Xtreme-Everest medical research expedition to the summit of Mount Everest (8850m) in the spring of 2007, where the progress of 222 volunteers was studied en route to the roof of the world.

It has been previously demonstrated that a simple manoeuvre can have profound beneficial effects if carried out before cardiac surgery. Intermittent inflation of an arterial blood pressure cuff on the upper arm pre-operatively reduces the release of troponin (a marker of cardiac damage) post-operatively. This technique is referred to as 'remote ischaemic preconditioning'. The mechanism underlying remote ischaemic preconditioning is unclear. Previous work by our group has demonstrated alterations in local forearm oxygen levels in healthy subjects (measured by a non-invasive sticky probe on the hand) that may potentially relate to the mechanism. We wish to further explore this mechanism in a small group of healthy volunteers using the arterial occlusion technique. We shall be investigating the role which hypoxia and exercise play in this mechanism. Better understanding of this important process may help in the development of clinically relevant techniques for reducing damage following heart surgery.

If you are at all interested in volunteering and would like some more information please contact me at mukhtar.ahmed AT ncl.ac.uk

Cheers for reading this.

I just started another thread about the Caudwell Xtreme-Everest expedition, so I am pinging this thread too. Hope that Turtle can feed us with more information. And please tell us about the result of the tissue hypoxia research too. I'd love to know whether I should choke the chicken before/during a competition or not.
