Thread: Interesting Question

Why do signs of tetany occur when a person hyperventilates ??

I bet this is far fetched (his muscles gonna get tired before this happen). Anyways, how can you explain this ??

Don't google it out, it would be too easy..It's tricky, be careful....

because when a person hyperventilates it leads to respiratory alkalosis... alkalosis results in hypocalcemia

hyperventilation -- increase in blood ph - hypocalcemia - carpopedal spasm[tetany]

=============
Let me ask another question now.

What's do you mean by hyperventilation? What's difference between hyperventilation and hyperapnea?

I answered this to the doctor and he said it's only 50% correct.

The next 50% is "Why does hypocalcemia occurs on hyperventilation ??"

@ Vitrag
Hyperventilation occurs when depth and rate of breathing increases and patient is aware of it.

Hyperpnea is increase in rate and depth of breathing regardless of patient's subjective sensations.

I have not heard about this hyperbentilation !!

It was a spelling mistake dude.

Well, what's 100% then? i don't think any link missing in that mechanism.

The next 50% is this:

Hyperventilation----->Resp alkalosis--->Increased ca++ binding to albumin---->Decreased free Ca++ ------>Hypocalcemia----->Tetany!!

The remaining 50% is alkalosis increases affinity for Calcium and bound state of Ca increases while free state of Ca decreases. Rightly said by a4assasins...
