What are the performance of asthma?

Asthma is one of the most common symptoms of asthma. In mild asthma, wheezing is only at the end of breath. As the severity of the disease increases, wheezing continues throughout the breath. More severe asthma attacks, wheeze can also exist in the breathing process. Very severe asthma attack, may be no wheeze, due to severe airflow limitation and airway stenosis and respiratory muscle fatigue related. When the obstruction is mainly small airway, asthma can be no wheeze. Asthma is not the basis for the diagnosis of asthma.

Furthermore, wheeze may be associated with other airway obstruction, such as fibrosis and heart failure. Patients with vocal cord dysfunction may have a breath of wheezing (different from asthma polyphonic wheezing) the best smell and the location is the neck throat area. Bronchial softening and tracheal softening of patients can also be heard and monosonal wheezing. Exercise-induced asthma, wheeze after exercise, wheeze in patients with nocturnal asthma can occur at night.

Coughing may be the only symptom of asthma, especially exercise-induced asthma or nocturnal asthma. Generally speaking, cough is dry cough and non-paroxysmal. Children with nocturnal asthma usually cough at night and in the morning. There may be chest tightness or chest pain, with or without asthma symptoms, especially exercise-induced or nocturnal asthma.

Other nonspecific symptoms of infants or children may be recurrent bronchitis, bronchiolitis or pneumonia; persistent cough after cold. Chronic or recurrent bronchitis in children mostly asthma. Recurrent pneumonia is the most common disease in children.

Exercise-induced bronchial spasm

In patients with exercise-induced bronchial spasms, the clinical outcome is typical of asthma but only related to exercise. Typical symptoms include cough, wheezing, shortness of breath, chest pain or chest tightness. Some patients may also have sore throat or gastrointestinal discomfort. There may be airway expansion. If the exercise lasts more than about 10 minutes, followed by bronchial contraction, resulting in asthma onset, exercise time is shortened, the symptoms after exercise for 5-10 minutes. High-intensity exercise levels can lead to high-intensity asthma attacks, running more than walking can produce more symptoms.

Patients with exercise can be seen in patients with asthma symptoms and seasonal changes or environmental temperature and adaptive changes related. Other predisposing factors may be contaminants or upper respiratory tract infections. Dry air is more likely to cause obstruction than hot air. Therefore, athletes in the swimming and other sports have good tolerance.

But the patient may have typical symptoms of obstruction, exercise asphyxia, inhalation wheezing or wheezing, these are evidence of assessment of vocal cord dysfunction.

Outer lung manifestations

Specific reactive or allergic rhinitis, such as conjunctival hyperemia and inflammation, eye dark circles, nasal transverse wrinkles due to frequent irritation of nasal rhinitis, lavender nasal mucosa produced by allergic rhinitis may be manifested in patients without acute attack In patients. The turbinate may have erythema or hypertrophy.

Skin examination may have allergic dermatitis, eczema or other allergic skin diseases. Clubbing is not the characteristics of asthma, may be the characteristics of other diseases, need to rule out cystic fibrosis and other diseases.

Nocturnal symptoms

Most asthmatic patients have symptoms of one or two nights every month. Part of the reason is a super-reaction to circadian airflow. Children with nocturnal asthma usually cough at night and in the morning.
