Why carpopedal spasm seen in hyperventilation:
High-Yield Explanation
Hyperventilation | Alkalosis | increase in plasma protein binding to Ca++ | Overall decrease in serum Ca++ | Carpopedal spasm. At plasma calcium ion concentrations about 50 percent below normal, the peripheral nerve fibers become so excitable that they begin to discharge spontaneously, initiating trains of nerve impulses that pass to the peripheral skeletal muscles to elicit tetanic muscle
