Blood pressure?

[TSandM]

In general, the body has good compensatory mechanisms to make sure there's enough perfusion pressure to the brain and vital organs. Someone who has a low resting BP (as I do) might find that, after diving, and as a result of both exercise AND diuresis, it's easy to get lightheaded by standing up too fast. But the body will compensate, and the effects are temporary.

So how would this affect offgassing, or would it?

 

[tracydr]

Blood pressure is affected while diving and your BP will most likely rise under the water. If you go for PADI open water certification or even a discover diving class, PADI requires you to have a medical statement signed by your doctor clearing you to dive.

I have high blood pressure and am being treated for it with 10mg of Lisinopril. My BP medicine is an ACE inhibitor which has less side-effects under water. The main side effect is a cough - which luckily I did not have while diving.

Only you and your doctor know if you are well enough to dive. But don't let high BP scare you away. I'm glad I didn't let it scare me away. I had such a wonderful time diving.

Are you being treated?

If you're coughing from the ace have your doctor switch you to an ARB like cozaar. It bypasses the pathway that causes the cough and has the same effect on BP.

I'm sorry, I don't understand the question. How would what affect offgassing?

Lower blood pressure.

 

[TSandM]

Well, blood pressure is a product of cardiac output (total amount of blood going around the circulation) and resistance. Low blood pressure CAN indicate poor perfusion (low cardiac output) or low resistance, which is far more likely in a normal, healthy person. Low resistance means high flow, which means offgassing would proceed normally.

As a Diver-Medic in saturation ( down to 22ata. ), I had occassion to perform b.p. analysis on the divers, & the results did not differ significantly from surface values, save the normal factors that influence b.p.

So there you go. Proof right there in the pudding.

In fact, the only significant physiological difference noted was the approximate 47% reduction in physical stature due to the high ambient pressure...

...thank the lord we returned to full height upon reaching surface!

Now we know where trolls come from. They're really Pressure Induced Short StaturEd divers.

47% --> you *are* kidding right? Oh wait...the stature of what body part exactly...?

Indeed - wouldn't it be tragic if one's special purpose, well, never actually recovered from the cursed "H.A.P.S.S." ( High Ambient Pressure Shrinkage Syndrome ).

Still, should a lady ever complain, the story / excuse is sure to garner intense sympathy / empathy & a desire to heal perhaps?

Best to you's,
