Which of the following are common breathing emergencies?

Breathing emergencies are situations in which a person's ability to breathe is compromised, leading to insufficient oxygen intake and potentially life-threatening consequences. The correct answer identifies asthma attacks, choking, and drowning as common breathing emergencies.

Asthma attacks occur when the airways become inflamed and narrowed, making it difficult for individuals to breathe. This can result in wheezing, shortness of breath, and a sense of panic, requiring immediate intervention to restore proper airflow.

Choking happens when an object gets lodged in the airway, blocking airflow and preventing breathing. This situation necessitates quick action to dislodge the object, typically using Heimlich maneuver techniques, to prevent suffocation.

Drowning refers to a situation where breathing is interrupted by submersion in water. This can lead to hypoxia (lack of oxygen), which can cause loss of consciousness and death if not addressed promptly through rescue and resuscitation efforts.

The other options mention various health concerns that, while serious, do not directly relate to breathing emergencies. Thus, the choice of asthma attacks, choking, and drowning encompasses the key scenarios where breathing is immediately and critically affected, making it the most suitable selection for common breathing emergencies.
