<unk>  is an obstruction in the process of breathing.<unk> , as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the throat or windpipe, resulting in oxygen deprivation. Although oxygen stored in the blood and lungs can keep a person alive for several minutes after breathing stops,<unk>  often leads to death. This<unk>  was the fourth most common cause of unintentional injury-related deaths in the US in 2011. Over 4,000<unk> -related deaths occur in the United States every year. Deaths from<unk>  most often occur in the very young (children under 2 years old) and in the elderly (adults over 75 years). Foods that can adapt their shape to that of the pharynx (such as bananas, marshmallows, or gelatinous candies) are more dangerous. Providing immediate and appropriate first aid can solve this type of<unk>  (read below).
