Some physicians do not advise the paper bag rebreathing method (or limiting its use to one or two minutes) due to the possibility of inhaling too much carbon dioxide and decreasing inspired oxygen to a hypoxic patient. The same benefits can be obtained more safely from deliberately slowing down the breathing rate by counting or looking at the second hand on a watch. This is often referred to as "7-11 breathing", because a gentle inhalation is stretched out to take 7 seconds (or counts), and the exhalation is slowed to take 11 seconds. Most patients benefit from carefully, deliberately slowing down their breathing twice a day for five minutes at a time.[29] The goal is to reduce breathing to no more than five breaths per minute. The goal is to reduce breathing to no more than five breaths per minute. This helps retrain their habits and convince them that faster breathing is unnecessary. Acupuncture has recently been proposed as a treatment.[31] Buteyko Method is a medical breathing retraining therapy developed by Soviet Doctor Konstantin Buteyko. The goal of the therapy is to reduce minute ventilation or to breathe less, normalize the breathing pattern and restore normal breathing parameters. Causes Most cases are caused by anxiety or stress. However, medical conditions such as infection, blood loss, heart attack,[33] hypocapnia or alkalosis due to chemical imbalances, decreased cerebral blood flow, and increased nerve sensitivity may also underlie this symptom.[35] In one study, one third of patients with HVS had "subtle but definite lung disease" that prompted them to breathe too frequently or too deeply.[37] {{transF}} == 参见 == Hyperventilation Da Costa's syndrome Buteyko Method (Buteyko breathing retraining method) == 参考文献 == {{rewrite}} [38] Anxiety disorders Respiration [39] [40] [3] ^ [2] [5] ^ [4] [7] ^ [6] [8] ^ Ganong WF, Review of medical physiology, 15-th ed., 1995, Prentice Hall Int., London.
