Breathing Retraining: From Sick/Victims to Superhumans

Hyperventilation

Hyperventilation: Definition and Clinical Facts

Define hyperventilation

Hyperventilation is breathing more air per minute than the medical norm. Normal minute ventilation at rest for a 70-kg person is 6 L/min.

Hyperventilation causes alveolar hypocapnia (a lack of CO2). This reduces O2 transport to all vital organs and promotes chronic diseases.

Overbreathing is common in people with chronic diseases, as this Table shows.

Breathing rates in healthy, normal people vs diseases

For more details about hyperventilation, you can visit this highly-intelligent article from Wikipedia that assumes that hoverbreathing appears due to panic or some other situations, like those on the Moon: click here.
