Vasovagal crisis

**Crisis of vasovagal hypotension** is a rapidly developing state of acute decrease in blood pressure caused by dysregulation of peripheral vascular resistance while the patient maintains sufficient or increased cardiac output. The causes of fainting may be a decrease in venous tone, a sudden decrease in cardiac output

Symptomatic acute hyperventilation, characterized by respiratory instability and palpitations. The patient may experience a feeling of “fading,” “cardiac arrest,” a feeling of lack of air, and depression of consciousness. Among the possible causes in medicine are: 1. Most often, attacks occur against the background of: affective disorders, anxiety-vegetative reactions of various origins, obstructive forms of bronchial asthma, surgical operations, exacerbations of coronary heart disease. 2. May also occur in response to: psycho-emotional stress, smoking in small doses, physical inactivity, use of analgesics, reflex effects from foreign bodies in the respiratory tract. The condition is based on an increase in neuromuscular excitability and a decrease in the threshold of convulsive readiness of the nerve centers. Basic therapy consists of normalizing physical activity, increasing motor activity and reducing motor stereotypes; prescribing beta-blockers or inhaled anticholinergics; using hypno techniques
