airway obstruction
Introduction
Introduction Lesions that occur in any part of the airway can cause airway obstruction, which can cause difficulty breathing. The cause of obstruction may be mechanical obstruction in the airway or outside the airway, such as a tumor or foreign body, or airway stenosis caused by airway smooth muscle spasm, such as bronchial asthma caused by bronchospasm.
Cause
Cause
Tracheobronchial foreign body, acute laryngeal acute laryngeal edema, is an important cause of sudden airway obstruction common in children and adults. Bronchial asthma is another common cause of periodic acute airway obstruction.
Ventilation disorders caused by diseases inside and outside the respiratory tract, manifested as difficulty breathing. People with foreign body in the respiratory tract often show sudden dyspnea, and those caused by extra-respiratory factors are often chronic dyspnea.

For cases of airway obstruction, the first diagnosis should be clearly important for emergency patients. The location and cause of the disease should be determined based on the condition of the attack and the nature of the dyspnea. Diagnosis of airway obstruction is based on the symptoms and signs at the time of onset and the nature of the episode. Ventilation disorders caused by diseases inside and outside the respiratory tract manifest as dyspnea. Frequent respiratory dyspnea caused by foreign body in the respiratory tract is often caused by chronic dyspnea. Conscious breathing is suffocating. Clinical manifestations of increased respiratory rate, purpura rhythm and depth changes accompanied by enhanced respiratory muscle movement can affect cardiac function, can cause acute respiratory failure life-threatening.
Diagnosis
Differential diagnosis
Differential diagnosis
1. Respiratory stenosis: The respiratory tract is the passage through which the airflow passes when the lungs breathe. The respiratory tract of a lung vertebrate is divided into upper and lower parts: the nose, the sinuses, the pharynx and the larynx are called the upper respiratory tract. The trachea and its subsequent subdivisions are collectively referred to as the lower respiratory tract, or tracheal bundle.
2. Severe Acute Respiratory Syndrome: Severe Acute Respiratory Syndrome: It is called "atypical pneumonia" before the cause is identified. Infectious atypical pneumonia, also known as Severe Acute Respiratory Syndromes (SARS), is a main symptom of fever, dry cough and chest tightness caused by SARS-associated coronavirus. Respiratory failure is a new respiratory infection. The strong infectivity and rapid progression of the disease are the main features of the disease. Cases of airway obstruction should first be clearly diagnosed. This is especially important for emergency patients. The location and cause of the disease should be determined based on the condition of the attack and the nature of the dyspnea.
