Fainting Hyperventilation

Hyperventilation fainting (s. hyperventilatio; lat. ventilatio “ventilation, breathing”) is a severe complication (symptom) of neurosis (agitation syndrome), manifested by a short-term loss of consciousness, pallor of the skin, slow breathing, pathological dilation of the pupils, and motor restlessness.[1] . Manifests against the background of forced hyperventilation. An objective examination reveals hypercapnia. Observed in anxiety disorders, neuroses caused by shock, fear or psychogenic factors, frequent hysterical reactions, extremely rarely in persons without neurotic disorders. The cause of a hyperventilation syncope episode is the patient’s involuntary respiratory movements instead of the planned ones, which develop without his participation. Blood pressure and heart rate do not change.
