Difficulty exhaling

Introduction Dyspnea includes difficulty in breathing and difficulty in inhaling, and difficulty breathing (breathing in the breath) is an important symptom of respiratory insufficiency. It is the patient's subjective feeling of lack of air or breathing; and objectively manifested as changes in respiratory frequency, depth, and rhythm. Exhalation difficulty: due to weakened lung tissue elasticity, small bronchospasm or stenosis. Features: It is exhaling effort, prolonged exhalation time, often accompanied by wheezing. More common in bronchial asthma, chronic asthmatic bronchitis, chronic obstructive emphysema and so on.

Cause

Breathing difficulties may be caused by a bronchial infection. Due to weakened lung tissue elasticity, small bronchospasm or stenosis. Causes of the disease caused by respiratory diseases, including: upper respiratory tract disease, posterior pharyngeal abscess, tonsil enlargement, laryngeal foreign body, laryngeal edema, laryngeal cancer, etc. Stenosis and obstruction caused by bronchial diseases such as bronchitis, bronchial asthma, bronchiectasis, bronchial foreign bodies and tumors.

Features: It is exhaling effort, prolonged exhalation time, often accompanied by wheezing. More common in bronchial asthma, chronic asthmatic bronchitis, chronic obstructive emphysema and so on.

an examination

The symptoms of bronchial infection are cough, sputum, accompanied by poor exhalation (bronchospasm - wheezing), blood may not be high when bronchial infection, chest X-ray may have no obvious abnormalities, or only lung texture increased, such as sputum Yellowing, viscous, or increased sputum, often suggesting bacterial infection.

Combined with medical history, clinical manifestations of patients, further examination confirmed.

Differential diagnosis

Differential diagnosis

1. Airway obstruction: Lesions that occur in any part of the airway may cause obstruction of the airway, causing difficulty breathing. The cause of the blockage may be mechanical obstruction in the airway or outside the airway. For example, tumors or foreign bodies can also be airway stenosis caused by airway smooth muscle spasm, such as bronchial asthma caused by bronchospasm.

2. Respiratory failure: Respiratory failure is a serious disorder of lung ventilation or ventilation due to various reasons, so that effective gas exchange cannot be performed, resulting in hypoxia with (or without) carbon dioxide retention, resulting in a series of physiological functions and Clinical syndrome of metabolic disorders. Respiratory failure is an important part of respiratory physiology research, an important cause of death from respiratory diseases, and the application of various types of mechanical breathing devices and respiratory physiology devices in the respiratory failure care unit (RUCU) to achieve significant therapeutic effects. Respiratory failure relies solely on clinical diagnosis of arterial blood gas analysis.

3. Respiratory inhibition: Respiratory depression is more common in opioid poisoning:

(1) The clinical manifestations of mild opioid poisoning are headache, dizziness, nausea, vomiting, excitement or inhibition. The patient has illusions, lost time and space.

(2) There are three major signs of coma and dilated pupils such as needle tip size and severe respiratory depression during severe poisoning. Patients may have convulsions, closed jaws, and angular arches. Breathing becomes shallower and slower, followed by sigh-like breathing or tidal breathing, often accompanied by pulmonary edema. Acute poisoning died of respiratory failure within 12 hours.

(3) Chronic poisoning mainly manifests as loss of appetite, constipation, weight loss, aging and sexual dysfunction.

diagnosis
