hyperventilation = ↓ CO2 → vasoconstriction of cerebral vessels → dizziness/lightheaded.
↑ pH = ↓ calcium levels = tetany/perioral tingling/paresthesias.
Breathing into a paper bag reverses the symptoms because recycled air has a higher concentration of carbon dioxide than normal air.

namesthegame22 Worth noting: new Uworld Qs say Hyperventilation syndrome tx = 1st line: Reassurance and breathing training -Teach abdominal diaphragmatic breathing 2nd line: Low dose lorazepam ((Do not attempt paper bag breathing)) -- however this was NOT the official answer on this NBME Q +1
