What Is Hyperventilation Syndrome?

Hyperventilation syndrome is a group of symptoms caused by excessive ventilation that exceeds physiological and metabolic needs. There is no symptomatic characteristic, and when breathing is accelerated, arterial blood carbon dioxide partial pressure is low, respiratory alkalosis, and sympathetic nerve excitement, clinical manifestations of various symptoms. All symptoms can be explained by hyperventilation and respiratory alkalosis. Hyperventilation syndrome (hyperventilation syndrome) is a physiological and psychological reaction caused by acute anxiety. When the attack occurs, patients will feel a rapid heartbeat, palpitations, and sweating. Because they cannot feel the breath, they will breathe faster, causing carbon dioxide to continue Excreted and the concentration is too low, causing secondary respiratory alkalosis and other symptoms. Over-breathing is over-breathing, which causes respiratory alkalosis, causing numbness in hands and feet, and in severe cases, the limbs can twitch.

Hyperventilation syndrome (hyperventilation syndrome) is a group of symptoms caused by hyperventilation exceeding physiological metabolic needs. Intrinsic refers to the absence of any cause of organic lesions, and accelerated breathing movements during the onset, resulting in a reduction in arterial blood carbon dioxide partial pressure (less than 5kPa), respiratory alkalosis, and sympathetic nervous system excitement. Shows various symptoms. All symptoms can be explained by hyperventilation and respiratory alkalosis. Symptoms are related to abnormalities in the respiratory control system and loss of stability of spontaneous respiratory regulation (most likely high nerve structures above the brainstem, such as the thalamus). The concept of hyperventilation syndrome includes the following three meanings: there are somatic symptoms; there is a respiratory regulation abnormality that can cause hyperventilation; there is a causal link between physical symptoms and respiratory regulation abnormalities, which means that the physical symptoms are caused by breathing Caused by abnormal adjustment. Many organic diseases, such as hypoxemia, pneumonia, interstitial fibrosis, pulmonary embolism, congestive heart failure, metabolic acidosis, and fever, can be accompanied by hyperventilation. Blood gas analysis shows that PaCO2 decreases, but Does not fall into the category of hyperventilation syndrome. By treating the primary disease, hyperventilation can be relieved.

Hyperventilation syndrome is common in women with neurosis symptoms or factors that induce stress. Excessive ventilation is because you feel too hypoxic, and you feel life-threatening. Then you have panic attacks, especially near-death experience. Excessive ventilation is also good. Only excessive ventilation can prevent the heart and brain from hypoxia, and struggling to die Excessive ventilation, congenital heart and brain organic problems can not stay up too late, or you will experience near death. And the experience of near-death is hallucinations, neurological damage after excessive stagnation and serious thought.

Hyperventilation syndrome refers to the absence of any cause of organic lesions, and accelerated breathing movements during the onset, resulting in a decrease in carbon dioxide pressure of carbon dioxide differentiation of arterial blood (less than 5kPa), respiratory alkalosis, and Have sympathetic nervous system excitement, clinical manifestations of various symptoms.

When hyperventilation syndrome develops, the breathing deepens and the patient complains of breathing effort; chest tightness or suffocation may include chest pain, palpitations, and tachycardia. Numbness of the extremities and faces, twitching of hands and feet, muscle spasms and even rigidity, may also have headache, dizziness, and disturbance of consciousness. No positive signs were found on examination.

Hyperventilation syndrome can occur with respiratory alkalosis.

Blood gas analysis decreased PaCO2 and increased pH.

For tachycardia, abnormalities can be found on the electrocardiogram.

1. Medical history, which is common in women, has neurosis symptoms or factors that induce mental stress.

2. Clinical manifestations.

3. Laboratory inspection.

4. Test treatment, try to inhale the gas containing carbon dioxide, can prevent the occurrence of symptoms.

5. Except differential diagnosis.

Hyperventilation syndrome should be distinguished from diseases such as epilepsy, hypothyroidism, and hypoglycemia.

General processing

Explain the relationship between symptoms and hyperventilation to patients, relieve patients' mental burden, and eliminate fear. If necessary, give oryzanol, bromine, sedatives and other drugs.

Master the right breathing method

That is, abdominal breathing, slow breathing, reducing or eliminating the tendency of hyperventilation by slowing the breathing rate.

Repeated breathing therapy

Face mask (or pouch) is used for repeated breathing therapy during acute attacks to increase CO2 in inhaled gas and reduce symptoms.

Hyperventilation syndrome should be treated as early as possible, generally better.

Improve quality of life and avoid predisposing factors such as mental stress.
