Most common cause of airway obstruction in adult?
The most common cause of airway occlusion (airway obstruction) is choking on foreign objects. This means swallowing an obstructive object or having something lodged in your trachea causing the airway to lose its patency.
Why do you have to open airway quickly on a casualty that has no control over her muscles?
The brain can only survive without oxygen for a very short amount of time. The priorities in an injured person are to remove the person from the area of danger, then to ensure an adequate airway, breathing and assess circulation. Airway is the most important because without an open airway and adequate breathing to promote oxygenation of blood, all other interventions will fail. In the setting of injury, especially if there is potential for head or neck injury, cervical spine stabilization should be maintained. This means that when opening the airway, you should not extend the neck. Instead a jaw lift should be performed and an airway adjunct may be needed to lift the tongue from the oropharynx to open the airway. Breathing may need to be assisted if there are no spontaneous ventilations. This can be done mouth-to-mouth or with an assistive device, such as a bag-valve-mask. ---- her tongue may fall backward and obstruct her airway ---- For the Air Force SABC: her tongue may fall backward and obstruct her airway
What can be a major cause of an airway emergency?
Tongue
What can obstruct the airway in a cardic arrest?
An obstruction of the upper airway involves the blockage of the airway in the throat, trachea (airway going to the lungs) or the voice box. Multiple things can cause upper airway obstruction, such as foreign objects (choking), swelling due to allergic reaction and chemical or heat burns which cause blistering/swelling. Most of the time, people would first think of choking as causing an obstruction of the upper airway, even though there are a variety of causes.
What is the most common cause of airway obstruction in children?
Tongue
What is guedels airway for?
- Inserted in mouth, extending from the teeth to the oropharynx. - Prevents obstruction of the trachea by displacement of the tongue into the oropharynx. Keeps the airway open and keeps tongue in place which is handy for other procedures.
What is an aspirated object likely to obstruct?
An aspirated object is likely to obstruct the airway, causing difficulty breathing and potentially leading to choking. In severe cases, it can result in asphyxiation and even be life-threatening if not promptly addressed.
What is the most common cause of airway obstruction in an conscious patient?

What is the common cause of upper airway obstruction in a trauma patient?
TONGUe
What can happen unconscious casualty left on their back?
Its harder to breathe that way. Also, if there is evidence of trauma, blood or other fluids would collect in the patients airway. The tongue is also relaxed and it could fall backwards into the throat and stop air flow. And if they are breathing after having CPR performed on them, they could throw up from th air in their stomach and the vomit could obstruct the airway. Recovery position is ideal.
Why is genioglossus called the safety muscle of the tongue?
The genioglossus muscle is the muscle of the tongue. it's attached the base of the tongue to the inside front of the jaw bone. It pulls the tongue forward. In the people with obstructive sleep apnea, the genioglossus is more active in holding the airway open at rest. If it relaxes during sleep, the airway narrows and collapses. as it keeps the airway open thus saves life, it's called a life saving muscle.
What is the most common cause of airway obstruction in an unconscious supine patient?
The most common cause of airway obstruction in any patient - supine or not - is the tongue. This is why the first maneuver that should be performed on a patient not breathing is the head-tilt/chin-lift or the jaw thrust. This is to help clear the tongue from the airway and may allow the person to breathe again.
