  2. Hyperventilation - Wikipedia

    en.wikipedia.org/wiki/Hyperventilation

    Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [ 1 ] [ 2 ] [ 3 ] This leads to hypocapnia , a reduced concentration of carbon dioxide dissolved in the blood.

  3. Hyperventilation syndrome - Wikipedia

    en.wikipedia.org/wiki/Hyperventilation_syndrome

    Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...

  4. Permissive hypercapnia - Wikipedia

    en.wikipedia.org/wiki/Permissive_hypercapnia

    Symptoms of early hypercapnia (i.e. where PaCO 2 is elevated but not extremely so) include flushed skin, full pulse, extrasystoles, muscle twitches, hand flaps, and possibly a raised blood pressure. In severe hypercapnia (generally PaCO 2 greater than 10 kPa or 75 mmHg ), symptomatology progresses to disorientation, panic , hyperventilation ...

  5. Ventilation–perfusion mismatch - Wikipedia

    en.wikipedia.org/wiki/Ventilation–perfusion...

    The ventilation and perfusion are measured separately. If both scans are done simultaneously then it is called as V/Q scan. Ventilation Scan is done first as it is easy to wash out tracer gas from lungs with the help of hyperventilation than clearing the tracer radioactive material from blood.

  6. 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.

  7. Hypocapnia - Wikipedia

    en.wikipedia.org/wiki/Hypocapnia

    This explains the other common symptoms of hyperventilation—pins and needles, muscle cramps and tetany in the extremities, especially hands and feet. [ citation needed ] Because the brain stem regulates breathing by monitoring the level of blood CO 2 instead of O 2 , hypocapnia can suppress breathing to the point of blackout from cerebral ...

  8. Central neurogenic hyperventilation - Wikipedia

    en.wikipedia.org/wiki/Central_neurogenic...

    Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma. CNH is unrelated to other forms of hyperventilation, like Kussmaul's ...

  9. Hypoxic ventilatory response - Wikipedia

    en.wikipedia.org/wiki/Hypoxic_ventilatory_response

    Especially for lowlanders who traverse past 6000 meters in altitude, the limit of prolonged human exposure to hypoxia, HVR may result in hyperventilation and ultimately the deterioration of the body. Oxygen consumption is reduced to a maximum of 1 liter per minute.
