Cardiac asthma is not a common asthma and if not differentiated from bronchial asthma, incorrect treatment will cause serious consequences for the patient's health. Therefore, patients need to clearly and accurately distinguish between bronchial asthma and cardiac asthma to have the correct treatment direction.

Bronchiolitis is a lung infection caused by a virus, most commonly affecting young children and infants, that causes inflammation and blockage of the bronchioles in the lungs. It often flares up in the winter with initial symptoms similar to a common cold but then progresses to coughing, wheezing and sometimes difficulty breathing.

Most babies will catch up to seven colds in their first year of life, and the incidence is higher in daycare. Treatment of colds in babies is largely about relieving symptoms, such as treating a cough or runny nose. However, babies should be seen by a doctor if they have signs of a cold to make sure it is not pneumonia or another serious illness.

Children with wheezing and difficulty breathing when abnormal breathing sounds occur due to obstruction of the lower respiratory tract (from the thoracic trachea to the small bronchi). In particular, wheezing and difficulty breathing are common in children under 2-3 years old because the bronchi (lungs) are small in size and are susceptible to constriction, edema, secretion and obstruction when infected (30-40% of breastfed children have this symptom).

Wheezing in infants or young children is very common, with about 25% to 30% of infants having at least one episode of wheezing. By age three, this number rises to about 40% of children, and by age six, nearly half of children will have at least one episode of wheezing.

Salbutamol is a drug used to treat asthma in children. However, using the drug incorrectly and in the wrong dosage will cause unsafety and seriously affect the health of children.

Wheezing in infants and young children is a very common respiratory symptom. Most wheezing sounds are heard when the child breathes out, but wheezing can also occur when the child breathes in. This symptom should be distinguished from the wheezing sound caused by a stuffy nose due to a cough or cold.

Acute bronchiolitis is common in children under 2 years old, especially very young children who are still breastfeeding. The disease has many different levels, it can be mild and transient, the child will recover after a few days or it can be very severe, causing respiratory failure and death.

The cause of wheezing in children is mainly determined to be asthma. However, wheezing in children can also be caused by other reasons such as lung diseases, foreign bodies in the airways, ...

Wheezing is a high-pitched, whistling sound that occurs when the small airways are narrowed by bronchospasm, thickened mucous membranes due to inflammation, edema, excessive secretions, or foreign bodies in the airways. It is heard mainly during expiration due to some degree of airway obstruction. It has a variety of tones when the airways are narrowed to varying degrees, as in asthma. Monotone wheezing is produced in the larger airways during expiration, such as the trachea or distal bronchi.

Wheezing in infants and children < 5 years of age is very common. Over 30% of children under 3 years of age have at least one episode of wheezing, and about 50% of children under 5 years of age have at least one episode of wheezing. About half of children who have wheezing onset before age 3 will not have a recurrence by age 6.
