Hypotension/hypovolemia as a low-pass filter: I got cut, I went into shock, and then everything started sounding funny. I'd guess it was a 40 dB (±10) rolloff, which began near 200 Hz (±50) and left me with nothing above 1kHz. How in the world? Story, discussion of numeric estimates, off-the-cuff physiological speculations, etc... [more inside]

What is the underlying physiological cause for paresthesia (tingling of the fingers) secondary to hyperventilation?
Specifically, what metabolic or neurological process causes you to feel tingling in your fingers when you hyperventilate?
