What causes airway obstruction?
Blocked airways
A child’s risk of choking on food is highest before they have a full set of teeth or when the muscles involved in swallowing have not yet fully formed. Whole nuts, seeds, raw carrots cut into circles, grapes, and hot dogs are particularly hazardous for young children.
Small children often put foreign objects in their mouths as they explore the world. If a child inhales an object like a coin, button, or small toy, it can become lodged in the throat or esophagus. These passages are much smaller in children than in full-grown adults. Of all toys, balloons are the most common cause of choking death among children of all ages.
Strangulation
Window blind cords, drawstrings, scarves, necklaces, long ribbons, and other cords can get wrapped around a child’s neck and cut off the flow of oxygen. In 2011, the U.S. Consumer Protection Safety Commission designated drawstrings on children’s clothing as hazardous, and now most children’s outerwear has Velcro or snaps instead.
Suffocation
The majority of infant suffocation tends to occur when babies are asleep. Sleeping toddlers can suffocate on soft bedding, loose blankets, crib bumper pads, or in adult-size beds or furniture. Beanbag chairs, bunk beds, balloons, and toy chests with lids also pose suffocation hazards for young children.
Airway Obstruction | Diagnosis & Treatments
How is airway obstruction diagnosed?
A health care provider may order an x-ray or perform a bronchoscopy to determine if a child’s airway is blocked and the location of the blockage.
How is airway obstruction treated?
Treatment for a blocked airway depends on the size of the object and where it is lodged in the airway.
- The child may cough the item up or pass it through the gastrointestinal tract
- An emergency medical responder or other health care provider may be able to dislodge the item with thrusts to the child's back, chest, or abdomen.
- Surgery may be necessary to remove an item that has gotten stuck or is causing internal damage to the child's airways or stomach.
Parents should seek emergency medical care for their child right away if their child is struggling to breathe, turns blue, or has swallowed a magnet or battery.
