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.
airway length - a large surface area means more friction airway radius - halving the radius increases resistance 16-fold flow rate
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.

In aviation, an airway is a designated route in the sky that aircraft follow when flying from one point to another. These airways are established to facilitate safe and efficient navigation and are defined by specific waypoints, altitudes, and air traffic control procedures. They help organize air traffic and reduce the risk of collisions by providing structured paths for aircraft in controlled airspace.
The proper airway management technique is to first, sweep the mouth and check the airway for obstructions. Then position the person's head so that the airway is as open as possible to facilitate breathing.
maybe airway obstructions, or lack of hemoglobin which carries oxygen, somethings like that.

The most common location of airway obstruction is in the throat, particularly at the level of the larynx or trachea. This can be due to various factors such as infections, swelling, foreign objects, or anatomical issues. Immediate medical attention is needed to address airway obstructions to prevent respiratory distress.
Tracheal obstructions can cause partial to full blockage of the airway. If the obstruction is not removed or expelled, it can cause of loss of consciousness or death.
I Believe what you mean is a foreign body airway obstruction. Essentially this is just the same thing as saying someone is choking. You have 2 types, total and partial airway obstructions. Any object that blocks the airway is considered to be an obstruction. The tongue itself can be one. If this isn't what you're looking for please feel free to revise this.
No, a tracheostomy tube does not go directly into the lungs; instead, it is inserted into the trachea (the windpipe) to create an airway. The tube allows for breathing and can help bypass obstructions in the upper airway. It provides a direct pathway for air to enter the lungs, but it does not extend into the lung tissue itself.
Three that come to mind are adenovirus, influenza, and RSV.
When the epiglottis, which is a flap of tissue that covers the trachea during swallowing, fails to close properly, food can enter the airway and cause choking. This can happen due to various reasons such as weakness in the muscles controlling swallowing or obstructions in the airway.
