What is the most common cause of airway obstruction in adults?
Acute upper airway obstruction can be caused by foreign body aspiration, viral or bacterial infections (croup, epiglottitis, tracheitis), anaphylaxis, burns or trauma. Show
Clinical featuresClinical signs of the severity of obstruction:
Management in all cases
Management of foreign body aspirationAcute airway obstruction (the foreign body either completely obstructs the pharynx or acts as a valve on the laryngeal inlet), no warning signs, most frequently in a child 6 months-5 years playing with a small object or eating. Conscience is initially maintained. Perform maneuvers to relieve obstruction only if the patient cannot speak or cough or emit any sound:
Heimlich manoeuvre: stand behind the patient. Place a closed fist in the pit of the stomach, above the navel and below the ribs. Place the other hand over fist and press hard into the abdomen with a quick, upward thrust. Perform one to five abdominal thrusts in order to compress the lungs from the below and dislodge the foreign body.
Place the infant face down across the forearm (resting the forearm on the leg) and support the infant’s head with the hand. With the heel of the other hand, perform one to five slaps on the back, between shoulder plates. Repeat until the foreign body is expelled and the patient resumes spontaneous breathing (coughing, crying, talking). If the patient loses consciousness ventilate and perform cardiopulmonary rescucitation. Tracheostomy if unable to ventilate.

What are the four most common causes of airway obstruction?Here are the five most common causes of upper airway obstruction.. Tongue-Related Airway Obstruction. ... . Foreign Body Lodged in the Airway. ... . Swelling. ... . Infection. ... . Trauma.. Which commonly causes obstructed airway in adults?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.
Which airway obstruction is the most common one?The most common cause of chronic upper airway obstruction in adults is OSA. Less common but potential causes of laryngeal pathology and subsequent airway compromise are tuberculosis, sarcoidosis, granulomatosis with polyangiitis, and Behcet disease.
What is likely to cause an airway obstruction?Causes of airway obstruction include deviated septum, foreign body ingestion, macroglossia, tracheal webs, tracheal atresia, retropharyngeal abscess, peritonsillar abscess, rhinitis, polyps, enlarged tonsils, lipoma of the neck, nasopharyngeal/oropharyngeal cancers, edema from epiglottitis, blunt or penetrating trauma, ...
