Upper Airway: Ear, Nose ,Throat

The eye, nose, and throat (ENT) are often sites of allergic reactions to airborne and food antigens. Hay fever is the most clear-cut case of allergy. Inhaled allergens such as grass pollen, meets antibody-coated mast cells waiting in the mucosal surface of the nose. A typical hay fever attack includes sneezing, nose itching and nose congestion.

A similar reaction in the throat produces soreness, mucus flow, swelling, and difficulty in swallowing and breathing (pharyngitis, laryngitis). A similar reaction in the lungs produces cough, mucus obstruction to airflow, and asthmatic wheezing (bronchitis, asthmatic bronchitis). This immediate allergic response can activate delayed cell-mediated immune activity which extends the disease from hours to days. Repeated antigenic stimulus then prolongs tissue inflammatory events toward chronic disease.

Airway

Air enters the body through the nose and mouth. The nose cleans, warms and humidifies inspired air. Air entering the mouth is less effectively cleaned. Inspired air then travels through the pharynx (throat) and enters the trachea.

The pharynx spits into two tubes, the trachea in the front and the oesophagus in the rear. Breathing and swallowing compete for the pharyngeal space. If food is inhaled by mistake, the airway is blocked. Vigorous coughing can clear the airway, but a stubborn obstruction can end life unless a good Samaritan intervenes with the Heimlich manoeuvre. By vigorously compressing the upper abdomen, air is forced from the lungs. In the best case, a tracheal obstruction is cleared. As long as food and beverages move to the rear and descend in the oesophagus, the airway remains secure.

In emergency medicine the upper airway is the first concern. You learn to assess and clear the airway of a patient first, then confirm breathing, then confirm cardiac status-- check heart beat and blood pressure.  The airway can be obstructed in many ways and must be clear before a life can be saved. Securing the airway is done with suction to clear liquids that accumulate in the pharynx and by plastic tubes that connect the outside air with the trachea. If the upper airway is damaged or cannot be secured. A tube is inserted into the trachea below the larynx to allow air flow directly into the lungs.

The Allergy Center is devoted to explaining a complicated subject. We offer rich resource online and encourage our readers to further pursue their interest by reading our books. Managing Food Allergy described in detail this import topic with discussions of chronic ill-defined diseases, autoimmune diseases and gluten allergy. The book, Gluten Problems and Solutions describes the best know pattern of food allergy triggered by the proteins in cereal grains. The book, Air and Breathing discusses airborne and food allergy as causes of respiratory disease. Immunology Notes explains in more detail how the immune system works and how immune mediated diseases develop. Many Alpha Education books refer to the Alpha Nutrition Program, a standard method of diet revision originally designed to solve the problems of food allergy. Starter Packs bundle the Alpha Nutrition Program, other books and formulas to help you get started solving your medical problems.
