Answer:
The Heimlich maneuver, also known as abdominal thrusts, is a first aid technique used to clear a blocked airway in a person who is choking. It is not intended for any other medical condition or emergency situation. Therefore, the correct answer to the question is b) A blocked airway.
Step-by-step explanation:
When a person's airway becomes obstructed by a foreign object or food, it can lead to choking. Choking occurs when the flow of air to the lungs is partially or completely blocked, preventing the person from breathing properly. This can be a life-threatening situation that requires immediate intervention.
The Heimlich maneuver was developed by Dr. Henry Heimlich in the 1970s as an effective method to dislodge an obstruction from the airway and restore normal breathing. It involves applying sudden upward pressure on the diaphragm, which creates an artificial cough and expels the object causing the blockage.
To perform the Heimlich maneuver on a conscious adult or child over one year old, follow these steps:
1. Stand behind the person and wrap your arms around their waist.
2. Make a fist with one hand and place it just above the navel, thumb side against the abdomen.
3. Grasp your fist with your other hand and give quick inward and upward thrusts to create pressure on the diaphragm.
4. Repeat thrusts until the object is expelled or the person becomes unconscious.
If the person becomes unconscious, you should immediately begin cardiopulmonary resuscitation (CPR) and call for emergency medical assistance.
It is important to note that the Heimlich maneuver should only be performed on individuals who are conscious and unable to breathe due to a blocked airway. It should not be used for other conditions such as a bloody nose (a), falling out of bed (c), or impaired eyesight (d). In these situations, appropriate first aid measures or medical attention should be sought.
In conclusion, the Heimlich maneuver is a technique used to clear a blocked airway in a person who is choking. It should only be performed on conscious individuals who are unable to breathe due to an obstruction. Prompt action and proper execution of the maneuver can save lives in choking emergencies.
