How is airway resistance Regulated?
Airway resistance is primarily regulated by the diameter of the airways, which can change due to various factors. Smooth muscle contraction or relaxation in the bronchial walls, influenced by autonomic nervous system activity and inflammatory mediators, plays a key role in this regulation. Additionally, factors such as airway inflammation, mucus production, and external stimuli like allergens or smoke can also impact airway resistance. Overall, these mechanisms work together to maintain optimal airflow during breathing.
What are three airway obstructions?
Three common types of airway obstructions include foreign body aspiration, which occurs when an object lodges in the airway; swelling from anaphylaxis or severe allergic reactions, which can restrict airflow; and mucus plugs, often seen in conditions like asthma or chronic bronchitis, that block the airways. Each of these obstructions can lead to difficulty breathing and requires prompt medical attention.

What protection do you have against food going down the wrong pipe?
The epiglottis is a flap that acts like a "door" and seals off your airway while you are swallowing food, and then opens to allow you to breathe when you are not swallowing food. When you are eating, make sure that you do not talk, as this interferes with the function of the epiglottis and can cause food to enter your airway.
Why would you insert an oral airway?
If a person becomes unconscious, an airway may be used to insure that the airway stays open.
