Closure

Closure of the airway is a medical condition that occurs when the airway becomes blocked, preventing air from entering the lungs. It can occur suddenly or gradually, and is often caused by a foreign object, swelling, or muscle spasms. Symptoms of closure of the airway include difficulty breathing, wheezing, coughing, and a feeling of tightness in the chest. In severe cases, the airway can become completely blocked, leading to loss of consciousness and death. Treatment depends on the cause and severity of the symptoms, and may include removal of the object, medications, or surgery.
