The presence of chest tightness, shortness of breath, and congestion in the throat requires consideration of a pharyngeal obstruction, such as the inhalation of a foreign body that obstructs the airway and causes a state of hypoxia. Acute infections, such as viral, bacterial, mycoplasma, chlamydia, or even fungal invasion, can cause significant congestion, edema, and blockage of the airway in the throat, resulting in hypoxia and even asphyxia. It is also seen in persistent attacks of bronchial asthma, where continuous spasm of bronchial smooth muscle and a large amount of inflammatory secretions exude and sputum plugs can block the airway. The airway should be unblocked early to prevent respiratory failure, such as bronchodilators, glucocorticoids for nebulized inhalation therapy, and intravenous drips to relieve symptoms.
