Chronic Hyperventilation Syndrome
Hyperventilation syndrome (chronic hyperventilation) is a physiological state characterized by chronic overbreathing or breathing more air than the medical-norm amount.
Normal minute ventilation at rest is about 6-7 L/min for a 70-kg man, as it was found in numerous studies done on healthy subjects (see the links and Table below).
Hyperventilation syndrome leads to reduced CO2 content in the alveoli of the lungs or alveolar hypocapnia. For most people, it also causes arterial hypocapnia (or CO2 deficiency in the arterial blood).
Minute ventilation rates (chronic diseases)
Note that advanced stages of asthma can lead to lung destruction, ventilation-perfusion mismatch,
and arterial hypercapnia causing further reduction in body oxygen levels.
Presence of hyperventilation syndrome in the sick is a common clinical finding owing to the fact that development of many chronic diseases is based on cell hypoxia. Many chronic diseases (including heart disease, diabetes, asthma, COPD, cancer, sleep apnea, obesity hyperventilation syndrome, liver cirrhosis, hyperthyroidism, cystic fibrosis, epilepsy, panic disorder, bipolar disorder, dystrophia myotonica) are possible only in people with hyperventilation syndrome and hyperventilation of the lungs or alveolar hyperventilation, as this Table proves. This is regardless silly ideas about overbreathing present in popular medical sources, such as Wikipedia: click here.
Chronic hyperventilation syndrome prevalence
Chronic hyperventilation is also common in the general population these days. Normal minute ventilation values for modern "normal subjects" suggest that hyperventilation (20 medical studies) is present in over 90% of normal subjects (see links below). Their average minute ventilation is about 12 liters of air min at rest, while published studies devoted to normal minute ventilation in the healthy subjects found only 6-7 L/min.
