hyperventilation,

n 1. an abnormally prolonged, rapid, and deep breathing; also the condition produced by overbreathing of oxygen at high pressures. It is marked by confusion, dizziness, numbness, and muscular cramps brought on by such breathing.
n 2. rapid, deep, forced breathing frequently resulting from anxiety. It results in a transient loss of carbon dioxide and respiratory alkalosis. Symptoms include anxiety, circumoral numbness, tingling sensation, faintness, and occasionally, carpopedal spasms, tetany, and syncope.

hyperventilation, managing,

n the steps that may be taken to assist a patient who experiences sudden, increased respiration that may be the result of anxiety or pain; may include verbal reassurances, repositioning, or deep breathing exercises.

hyperventilation

1. increase of air in the lungs above the normal amount.

2. abnormally prolonged and deep breathing, usually associated with acute anxiety or emotional tension. A transient, respiratory alkalosis commonly results from hyperventilation. More prolonged hyperventilation may be caused by disorders of the central nervous system, or by drugs.
