hyperventilation

Examples of hyperventilation in the following topics:

• Breathing Patterns

  • It is important to distinguish these terms from hyperventilation and hypoventilation, which refer to abnormalities in alveolar gas exchange (and thus blood pH) instead of an altered breathing pattern, but they may be associated with an altered breathing pattern.
  • For example dyspnea or tachypnea often occur together with hyperventilation during anxiety attacks, though not always.

• The Reason for Breathing

  • Alkalosis can happen from hyperventilation (too much breathing) which removes too much carbon dioxide from the bloodstream.
  • Thankfully, negative feedback mechanisms exist so that hyperventilation and hypoventilation can be corrected.

• Adjustments at High Altitude

  • At high altitude, in the short term, the lack of oxygen is sensed by the peripheral chemoreceptors, which causes an increase in breathing rate (hyperventilation).
  • However, hyperventilation also causes the adverse effect of alkalosis due to increasing the rate by which carbon dioxide is removed from the body, which inhibits the respiratory center from enhancing the respiratory rate to meet the oxygen demands.

• Alkalosis

  • The main cause of respiratory alkalosis is hyperventilation, resulting in a loss of carbon dioxide.

• Hypoxia

  • Hyperventilation, the body's most common response to high-altitude conditions, increases alveolar pO2 by raising the depth and rate of breathing.
  • However, while pO2 does improve with hyperventilation, it does not return to normal.

• Disorders of Acid-Base Balance

  • To compensate for this, the traveler begins to hyperventilate, trying to expel excess carbon dioxide and bring pH back to normal.
  • Respiratory alkalosis is a medical condition in which increased respiration (hyperventilation) elevates the blood pH (a condition generally called alkalosis).

• Chemical Composition of Bone

  • To compensate for this, the traveler begins to hyperventilate, trying to expel excess carbon dioxide and bring pH back to normal.
  • Respiratory alkalosis is a medical condition in which increased respiration (hyperventilation) elevates the blood pH (a condition generally called alkalosis).

• Substance Abuse and Health

  • Short term effects can manifest in the form of drowsiness and changes in breathing (slow breathing or hyperventilation), abdominal cramping, diarrhea, irregular heart rate, and even strokes.

• Chemoreceptor Regulation of Breathing

  • Consider a case in which a person is hyperventilating from an anxiety attack.

• Acidosis

  • This is a result of stimulation to chemoreceptors, which increases alveolar ventilation, leading to respiratory compensation, otherwise known as Kussmaul breathing (a specific type of hyperventilation).
