Section of larynx showing aspirated fragment of meat (top center). Most cases of<unk>  are in children ages 6 months to 3 years due to the tendency for children to place small objects in the mouth and nose. Children of this age usually lack molars and cannot grind up food into small pieces for proper swallowing. Small, round objects including nuts, hard candy, popcorn kernels, beans, and berries are common causes of<unk> . Latex balloons are also a serious choking hazard in children that can result in death. A latex balloon will conform to the shape of the trachea, blocking the airway and making it difficult to expel with the Heimlich maneuver. In addition, if the<unk> <unk>  is able to absorb water, such as a bean, seed, or corn, among other things, it may swell over time leading to a more severe obstruction. In adults,<unk>  is most prevalent in populations with impaired swallowing mechanisms such as the following: neurological disorders, alcohol use, advanced age leading to senility (most common in the 6th decade of life), and loss of consciousness. This inadequate airway protection may also be attributed to poor dentition, seizure, general anesthesia, or sedative drug use.Chest x-ray of an adult with obstructive pneumonia in the right lung (left side of the image) evidenced by hypodense (less dark) area. This is from a blockage in the respiratory tract leading to an infection distal to the obstruction.
