A few questions about breathlessness. 15

Dyspnea: refers to the subjective feeling of insufficient air and strained breathing.

Pulmonary dyspnea:

1. Inspiratory dyspnea: dyspnea is characterized by inspiratory dyspnea, accompanied by hoarseness or loss of voice, inspiratory wheezing, deep and not fast breathing, strengthened respiratory muscle movement during inhalation, suprasternal fossa and intercostal depression may occur, often accompanied by dry cough.

2. Expiratory dyspnea: The clinical characteristics are laborious exhalation, prolonged and slow exhalation time, often accompanied by wheezing. It occurs by decreased alveolar elasticity and/or obstruction of the small bronchial tubes (spasms or occlusive inflammation). It is commonly seen in bronchial asthma, chronic obstructive pulmonary disease, etc.

3. Mixed dyspnea: the clinical characteristics are that both inhalation and exhalation are laborious, breathing is shallow and fast, often accompanied by abnormal breath sounds (weakened or disappeared) and pathological breath sounds. The mechanism of its occurrence is due to extensive lung lesions and a reduction in the respiratory area, which affects the ventilation function.

It is common in severe pneumonia, severe tuberculosis, large atelectasis, massive pulmonary infarction, massive pleural effusion, and pneumothorax.

Causes of symptoms:

Respiratory system erect fibrous disease:

1. Obstruction: such as inflammation of larynx, trachea, bronchi, edema, stenosis or obstruction caused by tumor or foreign body, bronchial asthma, chronic obstructive pulmonary disease, etc.

2. Lung diseases: such as pneumonia, lung abscess, tuberculosis, atelectasis, pulmonary congestion, pulmonary edema, diffuse pulmonary residual interstitial disease, bronchiolar alveolar carcinoma, etc.

3. Chest wall, thoracic cavity, pleural cavity diseases: such as chest wall inflammation, severe thoracic deformity, pleural effusion, spontaneous pneumothorax, extensive pleural adhesions, tuberculosis, trauma, etc.

4. Neuromuscular diseases: such as poliomyelitis lesions involving the cervical spinal cord, acute polyradiculoneuritis and myasthenia gravis involving respiratory muscles, and drugs causing paralysis of respiratory muscles.

5. Diaphragmatic dysfunction: such as diaphragmatic paralysis, large amount of ascites effusion, huge abdominal tumor, gastric distension and the end of pregnancy.

Dyspnea refers to the patient's perceived lack of air, labored breathing, often accompanied by changes in respiratory rate, depth and rhythm, and in severe dyspnea, the mouth is open and orthopnea and retraction signs (the suprasternal fossa, supraclavicular fossa, and intercostal space are significantly decreased during inspiration), accompanied by high-pitched wheezing during the inspiratory phase.

Difficulty refers to the patient's feeling of poor breathing, chest tightness, and labored breathing, and the degree and nature of the patient's performance are different.

Dyspnea is often accompanied by an increase in respiratory rate, intensity, and may also be accompanied by changes in respiratory rhythm.

In severe cases, there may be irritability, orthopnea, or even mouth breathing, if our parents carefully observe the situation, we can find that the child has three retractions, the face becomes pale, and even becomes blue all over the body, which is actually a manifestation of hypoxia caused by dyspnea.

Disease analysis: generally cause dyspnea, the most common disease is respiratory diseases, such as bronchitis, pneumonia, bronchial asthma, in addition to heart disease, such as cardiac insufficiency, sometimes anemia patients, may also cause dyspnea, so dyspnea, you should go to the hospital to do a relevant examination, to see what the specific cause is, there is inflammation on the use of antibacterial and anti-inflammatory drugs**.

Dyspnea, that is, shortness of breath, chest tightness, people will be very uncomfortable, there is a feeling of suffocation, to go for a check-up.

Dyspnea refers to the subjective feeling of the patient, that is, the patient's subjective feeling of insufficient air and strained breathing, and objectively the patient will manifest as breathing and exercise force. Patients with severe dyspnea may also breathe through the mouth, flapping the wings of the nose, and orthopnea.

Dyspnea is a common symptom that refers to the patient's subjective perception of lack of air and difficulty breathing. Objectively it can be manifested in exertional exertion of breathing movements, mouth breathing, nasal flaring, orthostatic breathing, etc.

Common in: 1) Respiratory diseases.

1.Airway obstruction, such as asthma, inflammation or edema of the larynx or trachea or bronchi, or tumor compression.

2.Lesions of the lungs themselves, such as pneumonia, tuberculosis, atelectasis, pulmonary congestion, interstitial lung disease.

3.Chest wall, latocratic, pleural cavity disorders such as thoracic platymality, pleural effusion, pneumothorax.

2) Diseases of the circulatory system.

It is commonly seen in left or right heart failure, cardiac tamponade, pulmonary embolism, pulmonary hypertension, etc.

3) Poisoning. It is commonly seen in diabetic ketoacidosis, morphine and other drug poisoning, organophosphate pesticide poisoning, cyanide poisoning, nitrite poisoning, carbon monoxide poisoning.

4) Neuropsychiatric disorders.

Cerebral hemorrhage, traumatic brain injury, brain tumor, encephalitis, meningitis, brain abscess, etc., causing respiratory disorders, or mental factors such as anxiety disorders, hypothesis.

5) Blood disorders.

For example, severe anemia, methemoglobin blood symptoms.

Among them, respiratory diseases lead to lung ventilation, pulmonary ventilation disorders. The circulatory system can lead to dysregulation of ventilation and blood flow, resulting in dysventilation. Poisoning can lead to hemoglobin degeneration or abnormalities in the respiratory center. Blood disorders can cause impaired oxygen transport.

In general, it is to cause the body's reaction or feeling after causing the body to lack oxygen.

Dyspnea refers to the patient's subjective feeling of insufficient air, strained breathing, objective performance of respiratory exercise force, in severe cases, mouth breathing, nasal flaring, orthopnea, and even cyanosis, respiratory accessory muscles involved in respiratory movements, and there may be changes in respiratory rate, depth, and rhythm.

It's just that you can't breathe well, you can't breathe,。。
