Inspiratory dyspnea and expiratory dyspnea are common

Please determine whether it is inspiratory dyspnea alone, whether it is accompanied by expiratory dyspnea, or the cause of inspiratory dyspnea.

Extrathoracic obstruction of the large airways is the most common cause, and diseases that cause it are acute laryngitis, laryngeal edema, laryngeal cancer, tracheal tumors, airway foreign bodies, extratracheal tumors, or enlarged thyroid compression, all of which can occur during the winter months. If it is a physical examination, it is recommended to carefully observe the three recesses and auscultation, percussion of both lungs, and if it is an auxiliary examination, it is recommended to do a chest X-ray and chest CT.

Most other disorders are associated with expiratory dyspnea.

Age? Do you have high blood pressure, diabetes, or smoking?

This is important.

If you are young, (under 40 years old).

Don't be nervous, it may be cardiac neurosis.

Cardiac neurosis refers to the fact that there may be symptoms similar to angina, but there is no structural or functional abnormality of the heart itself.

That is, there is no difference between the heart itself and the heart of a healthy person.

It is more common in young women, and the incidence rate in men is slightly lower, simply put, it is similar to the symptoms of neurasthenia, which can be accompanied by insomnia and dreams.

If you are middle-aged and elderly, and have underlying diseases such as hypertension and diabetes, and the pain is in the retrosternal or precordial area, and the pain lasts for a few minutes, then it is recommended to do an electrocardiogram, because there is a possibility of coronary heart disease.

If you cough, a chest X-ray is also taken.

Word for word, I hope it helps you.

Good luck.

Answer]: Episodic expiratory dyspnea with wheezing or episodic chest tightness and cough are the main symptoms of bronchial asthma.

Answer]: B Analysis: In patients with severe inspiratory breathing and erection congestion, the "three retraction signs" can be seen, which is manifested as suprasternal fossa, superior clavicle fossa and intercostal space depression, and residual curvature is a typical manifestation. Master the knowledge of "dyspnea".

Inspiratory dyspnea is often caused by obstruction of the large airways, you may not have had the shape of your trachea when you were a hunched back, but now it may have changed, and have you smoked or been exposed to dust for a long time? It is recommended to do chest CT and pulmonary function tests to clarify the cause and seek medical attention in time.

If asthma is suspected, it is not difficult to diagnose it by going to the hospital for pulmonary function tests or bronchial provocation tests.

Dyspnea caused by upper airway obstruction is called inspiratory dyspnea; Dyspnea caused by lower airway obstruction is called expiratory dyspnea.

Expiratory dyspnea is dyspnea due to reduced elasticity of lung tissue and narrowing of small branch tubes. It is characterized by poor exhalation, labored expiration, prolonged expiration, and often wheezing. It is seen in bronchial asthma, obstructive emphysema caused by various causes, spastic bronchitis, etc.

Inspiratory dyspnea is seen in narrowing and obstruction of the larynx, trachea, and large bronchi caused by various reasons: laryngeal diseases, such as acute laryngitis, laryngeal edema, laryngospasm, diphtheria, laryngeal cancer, etc.; Tracheal diseases, such as bronchial tumors, tracheal foreign bodies, or tracheal compression (enlarged thyroid, lymphadenopathy, or compression of aortic aneurysms). It is characterized by marked difficulty inhaling, extreme tension of the respiratory muscles in high stenosis, marked subsidence of the suprasternal fossa, supraclavicular fossa, and intercostal space during inspiration (called the retraction sign), often accompanied by frequent dry cough and high-pitched inspiratory stridor.
