Free diving equipment....?

What do freedivers (as in competitive apnea) use as equipment? except their mask and their wetsuit, what else do they use (including things like ballast, rope, etc).
And please give me an average cost also.

http://www.redefineyourlimits.com/index.htm?id=10411

I live near Austin and my SCUBA instructor is friends with this woman Tana Streeter, she is a world champion freediver. Maybe her site has a little more information about what equipment is required. She has her training regimen recorded on there, etc. I am not a good enough swimmer but she offers classes for people who can do that, like my SCUBA instructor. She can dive to the bottom of all the lakes in Austin easily!

what are the short term mechanisms of regulation of blood pressure?

In brief:
1,- Diameter of arterioles (the pressure exerted to bypass this resistance is squarely proportional to the inverse radius) in other words, when they decrease their caliber, the pressure falls, and if the muscles around them contract (periarteriolar sphincters) then the pressure rises,,,,normally, they are independant of the will, and innervated by the sympathetic system (peripheral nerves, of vegetative nature).....
2.- Cardiac output.....If resistance of the arterioles does not change, the acceleratiuon of the cardiac output, will icrease, because the same amount of blood, will have to overcome that "resistance" the blood pressure will rise...
3.- Viscosity of the blood.
Incresing blood viscosity, will icrease cardiac work to increase, and parallel to this, the systemic arterial pressure.....(like in dehydration, policythemia vera ,ibcrease of globulins in blood etc)
4.- Impulses of the brain that travel along the sympathetic nerves, that with cold, fear, persistant anxiety, loss o blood or hypovolemia, etc. will contract the periarteriolar "muscular sphincters" increasing the peripheral pressure, .....
5,. Negative (low blood pressure) is given by impulses in several organs of the walls of arteries called baro receptors (from the greek baros=pressure ...they are found in the bifurcation of the carotid arteries in the neck, in the anterior wall of the aorta, and the impulses travel to the brainstem, forcing it to lower the pressure in some cases....,

What will become of the poor traumatized children who Michelle Obama is forcing to eat healthy foods?

I spoke with a young girl recently who started crying (literally crying) when she explained how Michelle Obama was forcing her to eat pizza with whole wheat crust in her school.

The word "forcing" is not at all true, but I do realize this question is a bit tongue-in-cheek (hype and hyperbole) and not meant to be taken literally or seriously. There is even a hint of Stephen Colbert type of raw humor noted, so perhaps you could submit the concept as a potential script for "The Colbert Report" on Comedy Central...lol.

Is It Time To Call CPS?

I apologize if this is written/submitted into the wrong section.

Sounds like it is definitely time to make the call. If you or no one else stands stands up for the welfare of the children, who will? Right is right, whether she is about to become a family member or not. If the children life long enough, they could have permanent damage due to not having the proper care. If you know their situation and don't call, then part of that blame is on your shoulders.

SpO2% in high altitudes?

Hi, I live in the midwest 581 feet above sea level. My normal SpO2 is between 97%-99%. I am in Colorado Springs now and my SpO2 has only lowered to 95%. Shouldn't it be lower? My pulse oximeter has no problems that I know of.

SpO2 is just a Rough gauge of the O2 concentration in ur capillaries.. It does not signify much..

It is not only dependant on the Altitude, But also on the Persons ability to Oxygenate the Blood..

Ofcourse, in High altitude, SpO2 falls, But there will be a variable and an Unpredictable fall, It may fall by 5 points to u and 8 points in ur friend.. There are no standardised calculation for this..

If ur SpO2 is 95 why are u bothered..?? Its absolutely normal. As the altitude increases, O2 in air decreases, there will be some fall in the O2 saturation, But that does not mean that it should fall to certain extent only..!! Ur body would have responded to the Low O2 conc by increasing the Respiratory rate and Lungs would have become more efficient in Oxygenating the Blood.. Hence its Normal.. This process is called Acclimatisation..

And also, SpO2 reading of anything above 91 is absolutely normal... Many normal individuals even in the Lower altitudes will have SpO2 of 91 and they will be normal without any symptoms..

And during an asthmatic attack, the Lung looses its efficiency to Oxygenate the Blood efficiently, thats y the SpO2 falls... But this has nothing to do with altitudes.. And there are no chances of rise in SpO2 due to Asthma, there can only be fall...

Since urs is 95%, its absolutely normal and don bother about it.......

Are there any tips for a person with type 1 insulin dependent diabetes that would like to explore nature?

I am 30, and have been Type 1 insulin dependent for 22 years. I'd like to do things I've never done, such as camping. Does anyone know of any resources, or advice, that would help in this goal of mine? Those with experience are very valuable. Yes, besides being slightly over weight I am in good shape.

As a fellow diabetic and avid outdoors person myself I will just share with you what I have done for myself over the years. It is never a bad idea to take someone with you, but if you choose not to always make sure someone has a way of knowing where your at and the expected amount of time your to be gone. Regardless if your on a serious hike, or just have taken a long walk in the woods. It important that someone can locate you, and plus being diabetic you should also remember a few more things.

I personally have horses and go for trail rides that are miles long. Before I ever began doing these I talked to my doctor about adjusting my insulin dose to avoid hypoglycemia, however now that Im on the pump it has made life much easier (not sure if that is the case for yourself). When your outside enjoying yourself you dont want to have to worry about spending the entire time on low blood sugars
My advice would be to just pack a hike pack as I do; I include extra insulin, syringes/pump supplies, glucose meter/test strips. (Make sure you have enough test strips so you dont run out on your hike). I also always carry glucose tablets, with simple snacks like peanut butter crackers and trail mix. Also a bottle of water and gatorade are good too!
One more bit of advice is to make sure you have on comfortable boots/shoes so you dont get blisters. You know us diabetics can have a lot of feet problems! Lastly, remember to carry identification with you that states you have diabetes. Have fun, its a great activity that keeps your body healthy.
