About Hyper ventilation
Hyperventilation is breathing that is deeper and more rapid than normal. It causes a decrease in the amount of a gas in the blood (called carbon dioxide, or CO2). This decrease may make you feel lightheaded, have a rapid heartbeat, and be short of breath. It also can lead to numbness or tingling in your hands or feet, anxiety, fainting, and sore chest muscles. The symptoms of hyperventilation usually last 20 to 30 minutes and may include feeling anxious, nervous, or tense; feeling that you can't get enough air (air hunger) or need to sit up to breathe; a pounding and racing heartbeat; problems with balance, lightheadedness, or vertigo; numbness or tingling in the hands, feet, or around the mouth; chest tightness, fullness, pressure, tenderness, or pain. Hyperventilation is not a disease, but you may need to be checked by your doctor if you have repeated episodes of hyperventilation symptoms. If you have recurring symptoms, you might be diagnosed with a condition called hyperventilation syndrome (HVS).
