Shortness of breath

Introduction Shortness of breath, lack of gas, mostly caused by lack of oxygen, emotional stress. Shortness of breath (shortness of breath) is a common clinical respiratory symptom. It is often caused by respiratory diseases or early symptoms of respiratory insufficiency caused by organs or tissue lesions that affect breathing. The condition is further aggravated by respiratory distress or difficulty breathing. Respiratory failure and life-threatening.

Cause

Mostly caused by lack of oxygen, emotional stress.

The causes of shortness of breath are various, which may be caused by diseases of the respiratory system itself, or by systemic diseases such as central nervous system, cardiovascular, abdominal cavity, gastrointestinal tract, metabolism, endocrine and blood. Because of the anatomical and physiological characteristics of the respiratory system, infants are more prone to shortness of breath and respiratory distress once the disease affects breathing. It is often associated with early symptoms of respiratory insufficiency due to respiratory disease or control, organs or tissue lesions that affect breathing.

After chest radiograph, judge whether there is heart disease. Fine medical history collection and physical examination usually provide possible parts and causes of the disease, such as fever, foreign body inhalation, trauma, poisoning and other medical history can provide important clues for diagnosis. The physical examination assessment includes general response, state of consciousness, vital signs (heart rate, pulse, blood pressure, body temperature, etc.) in addition to respiratory rate, depth, rhythm, symmetry, respiratory effort (respiratory muscle work) and lung auscultation. Systemic perfusion, according to which the severity of the condition can be understood.

Differential diagnosis

Dyspnea is an important symptom of respiratory insufficiency. It is subjectively characterized by insufficient air or breathing, and objectively manifested as changes in respiratory rate, depth, and rhythm.

After chest radiograph, judge whether there is heart disease.

Most children with obvious shortness of breath may be accompanied by respiratory distress or difficulty breathing. Children with respiratory distress may not be accompanied by shortness of breath. This is more common in severe central infection or central nervous system depression caused by hypothermia, trauma, poisoning, etc., which may be characterized by slow and irregular breathing. Breathing distress and shortness of breath need to be identified. The cause of neonatal shortness of breath is different from other age groups. X-ray examination is required. No abnormalities are considered. Consider sepsis, hypoglycemia, metabolic causes, pain, fever, hyperthermia and withdrawal syndrome. If the results are abnormal, consider hyaline membrane disease, neonatal temporary shortness of breath, pneumothorax, mediastinal gas, inhalation, atelectasis, pulmonary edema, left to right shunt congenital heart disease, pleural effusion, pneumonia, congenital diaphragmatic Congenital cystic adenoid malformation and tracheoesophageal fistula.
