24 Possible Causes for Hypocapnia, Panic Attacks, Tetany

  • Hyperventilation

    This report describes a case of hyperventilation-induced hypocapnia resulting in tetany in a 16-year-old girl undergoing orthodontic extractions under intravenous conscious[] We’ve covered several panic attack symptoms in the course so far.[] Respiratory alkalosis causes tetany and other clinical manifestations. But hypokalaemia and such weakness is rarely found.[]

  • Bicarbonate

    By decreasing cerebral blood flow, alkalosis may lead to tetany, seizures, and decreased mental status.[] The following phenomena were observed: 1) hypercapnia and acidosis of central venous blood were prominent during both cardiogenic shock and CPR, although arterial hypocapnia[] attacks which is also thought to be the reason hyperventilation contributes to panic attacks (via increasing CO 2 intake relative to O 2 intake) [77] and persons with panic[]

  • Respiratory Alkalosis

    Respiratory alkalosis causes tetany and other clinical manifestations. But hypokalaemia and such weakness is rarely found.[] In both groups clear conditioning occurred, but there was no effect of hypocapnia. Results are critically discussed.[] attacks -Other diseases can mimic hyperventilation -Further hypoxia further cellular damage Respiratory Therapies, continued Teach breathing exercises Slow regular breaths[]

  • Panic Attacks

    "Incidence of Latent Tetany in Patients With Panic Disorder." Cesk Psychiatry 91.3 July 1995: 183-190. Wang, T., et al.[] Hyperventilation syndrome can cause respiratory alkalosis and hypocapnia . This syndrome often involves prominent mouth breathing as well.[] […] a change of the diurnal panic attacks, from spontaneous to situational pattern.[]

  • Psychogenic Hyperventilation

    In our opinion, "spasmophilia" (or tetany) is a sign of emergency stop when the "somnobar" is in the red zone (cf). So, it is not bad?[] […] high lactates are usually associated with acidosis and an increased risk of poor outcome, in patients with psychogenic hyperventilation, high lactates are associated with hypocapnia[] attack) or secondary to a renal colic.[]

  • Acute Hyperventilation

    Respiratory alkalosis accompanies the clinical syndrome of tetany, precipitates cardiac arrhythmias and predisposes to coronary vasoconstriction.[] Acute hypocapnia decreases CBF, increases hemoglobin affinity for oxygen and causes cerebral tissue hypoxia.[] […] of it recently again with a tight chest but tell myself its just the start of panic attacks and not to worry.[]

  • Graves Disease

    […] is the treatment of choice complications include recurrent laryngeal nerve injury hypocalcemia due to PTH gland removal resulting in the classic findings of hypocalcemia (tetany[] Later, after the misdiagnosed panic attack episode happened on the set of Murphy Brown, Ford knew she needed to take the advice of her co-star and go see a doctor.[] attacks, or mood disorders) Atrial Fibrilation Congestive Heart Failure [2] [4] [9] Case Reports/ Case Studies 37 year old woman with Palpitations and Fatigue [veiw article[]

  • Chronic Hyperventilation

    […] misconception that hyperventilation syndromes occur infrequently, are characterized by acute, dramatic, but transitory bouts of hyperpnea, and that they culminate in frank tetany[] […] according to a 60 min protocol in which periods of rest were replaced by exercise, voluntary hyperventilation (VHV), reading, and CO2 inhalation. 5 patients with severe resting hypocapnia[] Ambulatory Heart Rate Changes in Patients with Panic Attacks. American Journal of Psychiatry , 143 , 478–482.[]

  • Alkalosis

    […] neonatal tetany ( P71.3 ) parathyroid tetany ( E20.9 ) post-thyroidectomy tetany ( E89.2 ) alkalosis E87.3 ICD-10-CM Codes Adjacent To E87.3 E85.9 Amyloidosis, unspecified[] Hypocapnia. N Engl J Med. 2002;347:43-53.[] attacks Pregnancy High altitude Drug toxicity ( theophylline , progesterone , salicylate toxicity ) Hyperventilation while on mechanical ventilation CNS infections Sepsis[]

  • Neurocirculatory Asthenia

    In 1922, Goldman was the first to make the connection between "forced ventilation" and tetany and postulated that the tetany was due to alkalosis ( Goldman 1922 ).[] For example, hypocapnia affects cerebral blood flow, and the caliber of cerebral arteries is dependent on carbon dioxide.[] Orr, who has experienced panic attacks herself, kept a diary of her participation as a research subject in clinical trials for the Upjohn Company’s anti-anxiety drug Xanax[]
