The Buteyko method emphasizes the role of carbon dioxide and hyperventilation in respiratory diseases as well as overall health. It is known that hyperventilation can lead to low carbon dioxide levels in the blood (or hypocapnea), which can subsequently lead to disturbances of the acid-base balance in the blood and lower tissue oxygen levels.
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." Examples include smoke or other ...
Functional changes (increased RL and/or bronchial responsiveness to inhaled methacholine) last for mean intervals of 3 and 7 days after exposure, but can persist up to 30 and 90 days, respectively. The functional changes are related to the overall abnormal airway epithelial damage and there is a significant correlation between RL and ...
At high altitude, from 1,500 to 3,500 metres (4,900 to 11,500 ft) there are physiological effects of the reduced oxygen partial pressure which include reduced exercise performance and increased respiratory rate. Arterial oxygen saturation is generally still over 90% in healthy people, but arterial P O 2 is reduced. [2]
Well you're not alone -- as many as 60 million Americans have to deal with chronic sleeplessness each year. Before you let that number keep you up counting sheep, take a deep breath. Seriously ...
The risk of dangerous irregularities of the heart beat is increased. [ 6 ] [ 7 ] Hypercapnia also occurs when the breathing gas is contaminated with carbon dioxide, or respiratory gas exchange cannot keep up with the metabolic production of carbon dioxide, which can occur when gas density limits ventilation at high ambient pressures.
Carbon monoxide rebreathing is used to monitor athletes' haemoglobin levels, which are a predictor of exercise performance but there has been suggestions that repeated inhalation can be used to ...
