Airway obstruction is a blockage of respiration in the airway that hinders the free flow of air. Airway obstructions can occur either in the upper airway (UPA) or lower airway (LOA). The upper airway consists of the nose, throat, and larynx. The lower airway comprises the trachea, bronchi, and bronchioles. [1] Upper and lower airway
A little over 50% of all people with Down syndrome experience obstructive sleep apnea, [57] and some physicians advocate routine testing of this group. [58] In other craniofacial syndromes, the abnormal feature may actually improve the airway, but its correction may put the person at risk for obstructive sleep apnea after surgery when it is ...
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
“There’s a theory on why — the airway becomes obstructed, so the muscles in the mouth and jaw move to try to free the blocked airway. That’s not been proven, but it is an interesting ...
“When your mouth is open, the jaw moves down and back,” leading potentially to the partially blocked airway that’s often involved in the disorder, Olson says. Read More: ...
The term "Pickwickian syndrome" that is sometimes used for the syndrome was coined by the famous early 20th-century physician William Osler, who must have been a reader of Charles Dickens. The description of Joe, "the fat boy" in Dickens's novel The Pickwick Papers , is an accurate clinical picture of an adult with obstructive sleep apnea syndrome.
Usually, any medical condition where the airway is blocked during sleeping, like obstructive sleep apnea, may give rise to snoring. Snoring, when not associated with an obstructive phenomenon is known as primary snoring. [ 3 ]
Upper airway: Obstruction of the upper airway is common in infants less than 3 months old because they are nose breathers. Nasal blockage may easily lead to upper airway obstruction in infants. For other ages, upper airway obstruction may occur from a foreign body or edema of the pharynx, larynx, or trachea.
