Respiratory Symptoms
Respiratory symptoms are a defining characteristic of anaphylaxis. This is also one of the most prevalent and earliest signs of anaphylaxis. In its earliest phases, anaphylaxis may manifest similarly to allergy, with a runny nose and cough. The symptoms of anaphylaxis worsen over time. The patient improves
Severe wheezing causes continuous obstruction of the airways. Coughing also disrupts the airway of inspired air, resulting in insufficient breaths per minute.
Due to the constriction of balloon-shaped alveoli within the lungs, the lung tissue does not permit efficient contraction and relaxation, resulting in difficulty breathing. This causes the patient to experience extreme difficulty inhaling an adequate quantity of oxygenated air and to exhale all deoxygenated air.
Voice hoarseness and wheezing: The voice becomes hoarse, and difficult breathing manifests as long, laboured attempts to inhale oxygen and wheezing.
The thorax may feel constricted and tight.
All of these symptoms are caused by various anaphylactic mediators that are secreted in large quantities and bound to various receptors in the nose, windpipe, and other respiratory organs. At the majority of these sites, the effect of these mediators is to cause muscular contraction and constriction of the passage, resulting in symptoms of constriction.
