1. Hyperventilation

   Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. This leads to hypocapnia, a reduced concentration of carbon dioxide dissolved in the blood. The body normally attempts to compensate for this homeostatically, but if this fails or is overridden, the blood pH will rise, leading to respiratory alkalosis. The symptoms of respiratory alkalosis include: dizziness, tingling in the lips, hands or feet, headache, weakness, fainting, and seizures. In extreme cases it may cause carpopedal spasms, a flapping and contraction of the hands and feet.Factors that may induce or sustain hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, and adverse reactions to certain drugs. Hyperventilation can also be induced intentionally to achieve an altered state of consciousness such as in the choking game, during breathwork, or in an attempt to extend a breath-hold dive.

1. hyperventilation

   Hyperventilation is a condition characterized by rapid or deep breathing that can cause decreased carbon dioxide levels in the blood. This often leads to lightheadedness, dizziness, shortness of breath, and can sometimes lead to loss of consciousness. It can be triggered by various causes such as stress, anxiety, panic, or certain medical conditions.

1. Hyperventilation

   Hyperventilation or overbreathing is the act of breathing faster or deeper than normal, causing excessive expulsion of circulating carbon dioxide. This causes the arterial concentration of carbon dioxide to fall below normal, raising blood pH and resulting in alkalosis. It can result from a psychological state such as a panic attack or cold shock, from a physiological condition such as metabolic acidosis, lifestyle risk factors or voluntarily as in the yogic practice of Bhastrika. Distinct from labored breathing when that is a natural response to higher than normal carbon dioxide levels. Chronic obstructive pulmonary disease, asthma and multiple panic disorders have also been identified. Hyperventilation can sometimes cause symptoms such as numbness or tingling in the hands, feet and lips, lightheadedness, dizziness, headache, chest pain, flexor spasm of hands and feet, slurred speech, nervous laughter, and sometimes fainting, particularly when accompanied by the Valsalva maneuver. Counterintuitively, such effects are not precipitated by the sufferer's lack of oxygen or air. Rather, the hyperventilation itself reduces the carbon dioxide concentration of the blood to below its normal level because one is expiring more carbon dioxide than what is being produced in the body, thereby raising the blood's pH value, initiating constriction of the blood vessels which supply the brain, and preventing the transport of oxygen and other molecules necessary for the function of the nervous system. At the same time, hypocapnia causes a higher affinity of oxygen to haemoglobin, known as the Bohr effect, further reducing the amount of oxygen that is made available to the brain.

1. Hyperventilation

   A pulmonary ventilation rate faster than is metabolically necessary for the exchange of gases. It is the result of an increased frequency of breathing, an increased tidal volume, or a combination of both. It causes an excess intake of oxygen and the blowing off of carbon dioxide.

Examples of hyperventilation in a Sentence

1. Republican Rep. Jason Lewis:

   You've got to have a photo ID to get on an airplane, you've got to have a photo ID to take a college test, you've got to have a photo ID to cash a check and yet( then-US Attorney General) Eric Holder is rejecting the Texas voter identification laws. He's stopping the South Carolina voter identification laws. Why ? because he and( Jesse) Jackson and Al Sharpton are once again bringing out the race card in photo ID -- saying what ? Saying that having a photo ID requirement at the polls is inherently -- are you ready ? -- racist. Now this is the same sort of stretch, this is the same sort of hyperventilation that has brought Florida to the edge of a race war and now it's coming from the white side as well as the black side, tragically. Extremists on both sides.

2. Steve Ricchetti:

   Not a lot of drama. Not a lot of hyperventilation, just do the work.
