  2. Pursed-lip breathing - Wikipedia

    en.wikipedia.org/wiki/Pursed-lip_breathing

    Pursed-lip breathing increases positive pressure generated in the conducting branches of the lungs. [4] This can hold open bronchioles in patients with high lung compliance, such as those with emphysema. [4] Pursed-lip breathing also accesses the parasympathetic nervous system, which reduces stress during episodes of shortness of breath. [5]

  3. Hydreliox - Wikipedia

    en.wikipedia.org/wiki/Hydreliox

    It is used primarily for research and scientific deep diving, usually below 130 metres (430 ft). Below this depth, extended breathing of heliox gas mixtures may cause high pressure nervous syndrome (HPNS). [4] Two gas mixtures exist that attempt to combat this problem: trimix and hydreliox. Like trimix, hydreliox contains helium and oxygen and ...

  4. Buteyko method - Wikipedia

    en.wikipedia.org/wiki/Buteyko_method

    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.

  5. Conscious breathing - Wikipedia

    In tai chi, anaerobic exercise is combined with breathing exercises to strengthen the diaphragm muscles, improve posture and make better use of the body's qi. [1]In qigong, reverse breathing is a breathing technique which consists of contracting the abdomen and expanding the thoracic cage while breathing in through the nose and then gently compressing it while exhaling through the mouth, which ...

    A new analysis of breathing data from 52 volunteers over a 24-hour period revealed that people with a normal sense of smell had little spikes, or “sniffs,” during each breath that were not ...

  7. Work of breathing - Wikipedia

    en.wikipedia.org/wiki/Work_of_breathing

    The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

  8. Human physiology of underwater diving - Wikipedia

    en.wikipedia.org/wiki/Human_physiology_of...

    Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment. All of these may affect diver performance and safety. [1]
