Common Causes

• Partial airway obstruction: breathing laboured, gasping or noisy some air escaping from the mouth patient coughing or making a ‘crowing’ noise extreme anxiety or agitation
• Total airway obstruction:
• the person will be unable to effectively cough, breathe or speak, with no air movement

Airway constriction is a symptom of many medical conditions but most often is associated with various types of asthma and asthma-like conditions. For example: Allergic asthma: An allergy activates the immune system, causing the release of chemicals that lead to inflammation and cause constriction of the airways.

What are the causes of airway constriction?

You must always be prepared for loss of the airway because it can occur unexpectantly.

Tilting the head and pulling the jaw upward lifts this tissue off the larynx and opens the airway.

Children are more vulnerable because of their smaller airways. In newborns, upper airway obstructions, even partial ones, are particularly dangerous because newborns breathe through the nose.

Why does my tongue relax?

A relaxed tongue is the most common cause of upper airway obstruction in patients who are unconscious or who have suffered spinal cord or other neurological injuries. The tongue may relax into the airway, causing an obstruction. In some cases, other injuries complicate this phenomenon.

How many people die from asthma?

Twenty-six million Americans have asthma. Worldwide, at least 250,000 people die prematurely from asthma, but prompt medical care and diligent airway management has greatly reduced mortality in the U.S.

Can an allergy cause an obstruction of the airway?

Swelling can obstruct the airway in a matter of seconds. Though infections can cause severe upper airway swelling, the most common cause is anaphylaxis. Anyone with an allergy can have an anaphylactic reaction, even if they have been previously exposed to the allergen without such an extreme reaction. More than 32 million Americans have food allergies, putting millions at risk of swelling-related airway obstructions. Moreover, the prevalence of food allergies is increasing, with the rate of peanut allergies in children tripling between 1997 and 2008.

What causes anaphylaxis in the upper airway?

The most common causes of anaphylaxis include: Burns. When the air temperature gets hot enough, such as in a fire, it can injure your upper airway. These injuries cause swelling to your epiglottis, which is a flap of cartilage at the root of the tongue, and the mucous membranes around the larynx.
