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 ...
Factors that may induce or sustain [2] hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, [5] cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, [1] [3 ...
Empty Nose Syndrome; Other names: Secondary atrophic rhinitis: Altered nasal anatomy after bilateral subtotal inferior turbinectomy, the removal of most turbinate tissue. Specialty: Otolaryngology: Symptoms: Sensation of nasal suffocation despite clear airway: Complications: Hyperventilation syndrome, depression, anxiety, fatigue: Usual onset
Central neurogenic hyperventilation (CNH) is an extremely rare neurological disorder that was initially reported by Fred Plum, MD and August G. Swanson, MD, in 1959. [ 6 ] [ 11 ] [ 1 ] Plum and Swanson described the symptoms of nine comatose patients, defining CNH as a syndrome consisting primarily of elevated arterial oxygen tension, decreased ...
Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
Hyperventilation, the act of hyperventilating; Hyperventilation syndrome, a medical condition involving hyperventilating; Cheyne–Stokes respiration, the breathing disorder; Hypocapnia, a physiological result of hyperventilating "Hyperventilating" (song), a 2006 song by Tami Chynn
The main physiologic causes of hypocapnia are related to hyperventilation. Hypocapnia is sometimes induced in the treatment of medical emergencies such as intracranial hypertension [3] and hyperkalemia. Self-induced hypocapnia through hyperventilation is the basis for the dangerous schoolyard fainting game.
Hyperventilation may be entirely voluntary or in response to emotional agitation or anxiety, when it can cause the distressing hyperventilation syndrome. The voluntary control can also influence other functions such as the heart rate as in yoga practices and meditation .
