Does Chronic Hyperventilation Cause Brain Damage?

“Does chronic hyperventilation cause brain damage?” “…since it causes cerebral hypoxia due to low CO2 level, can we deduce that it cause brain damage?” Voluntarily hyperventilating is unlikely to cause any problems. Your brain and body is generally too intelligent to allow you to damage yourself in such a manner. Low CO2 levels from Hyperventilation can cause cerebral vasoconstriction and ischemia. This usually is only a seen in settings of artificial respiration. Well it does not directly cause brain damage. However, you are correct that it can cause brain damage indirectly. When you hyper ventilate, your brain becomes depleted of oxygen. This is not good. Extened periods of lack of oxygen can cause cells (and neurons) to become damaged, or even die. This should not really be a problem unless it is a regular occurance. Hyperventilating for a few seconds every day wont do much, but if you are hyperventilating for very long periods of time multiple times daily, this could be a problem. I strongly suggest you speak to a doctor about this if you are concerned. If I can help, I suggest practising breathing excersises regularly. This will allow you over time to become more in Continue reading >>

    If hyperventilation occurs, excess CO2 gets removed. This shifts the pH of the body slightly to a more alkaline ph (Since CO2 is acidic. Loss of Acid in body = Increase in pH). The change in pH can cause these effects.

    There is a delicate balance of gases in the blood, including oxygen and carbon dioxide, that regulate our system. Usually we think of oxygen as something we need to inhale and carbon dioxide as something to be expelled, but when you hyperventilate, you expel too much carbon dioxide. In the blood, carbon dioxide is important for maintaining the proper pH, as it acts as an acidifier. When too much of it is lost in a short amount of time, you go into a state of what’s called respiratory alkalosis, wherein your blood pH becomes too high or alkaline. This alkalosis causes the symptoms such as dizziness, tingling, fainting, and can even cause seizures and severe spasms if the body is unable to naturally compensate metabolically to reduce to pH of the blood to normal levels and/or the hyperventilation is stopped.

Ap2 Respiratory System Lecture

Sort breathing rate increases above normal. PO2 increase, CO2 decreases in alveoli.The hemoglobin saturation is already at 98% so more O2 can't come into the blood, however additional CO2 leaves the blood. Low blood CO2 decreases blood H+, so pH rises (respiratory alkalosis) causes dizziness and fainting hyperventilating to slow or too shallow breathing caused by airway obstruction or brainstem injury; O2 decreases, CO2 increases in alveoli, both pressure gradients are affected so both O2 & CO2 can't leave blood and go to aveoli. Blood pH may fall (increase H+ from CO2) , blood becomes more acidic (respiratory acidosis) hypoventilating Continue reading >>

    If you hyperventilate you ‘blow off’ the carbon dioxide in your blood very quickly. Carbon dioxide has an effect on cerebral blood vessels (the blood vessels in the brain).

  2. Jonas Grandt

    My best guess (which is better than nothing), is that rapid, shallow breaths use oxygen way faster than they collect, and they cannot effectively remove carbon dioxide from the bloodstream, leading to fainting through oxygen deprivation and carbon dioxide buildup. Once you've fainted, your breathing should return to normal, fixing both problems before much else happens.

Hyperventilation In Severe Diabetic Ketoacidosis.

Abstract OBJECTIVE: To explore whether the carbon dioxide-bicarbonate (P(CO(2))-HCO(3)) buffering system in blood and cerebrospinal fluid (CSF) in diabetic ketoacidosis should influence the approach to ventilation in patients at risk of cerebral edema. DATA SOURCE: Medline search, manual search of references in articles found in Medline search, and use of historical literature from 1933 to 1967. DESIGN: A clinical vignette is used--a child with severe diabetic ketoacidosis who presented with profound hypocapnia and then deteriorated--as a basis for discussion of integrative metabolic and vascular physiology. STUDY SELECTION: Studies included reports in diabetic ketoacidosis where arterial and CSF acid-base data have been presented. Studies where simultaneous acid-base, ventilation, respiratory quotient, and cerebral blood flow data are available. DATA EXTRACTION AND SYNTHESIS: We revisit a hypothesis and, by reassessing data, put forward an argument based on the significance of low [HCO(3)](CSF) and rising Pa(CO(2))- hyperventilation in diabetic ketoacidosis and the limit in biology of survival; repair of severe diabetic ketoacidosis and Pa(CO(2))-and mechanical ventilation.
