Question

Check your knowledge of 2-rescuer adult BLS by placing the steps in their proper sequence. In this scenario, assume that (1) the victim is unresponsive, is not breathing, and has no pulse; and (2) backup advanced life support teams are on their way to the incident.

Answer 1

The 2-rescuer adult BLS steps include ensuring scene safety, one rescuer performing compressions, the second rescuer giving breaths after every 30 compressions, switching roles to prevent fatigue, and continuing until advanced support arrives. Proper training is critical to administer CPR effectively and minimize the risk of injury.

Step-by-step explanation:

The correct sequence of steps for 2-rescuer adult Basic Life Support (BLS), assuming that backup advanced life support teams are on the way, and the victim is unresponsive, not breathing, and has no pulse, is as follows:

1. Ensure the scene is safe for you and the victim.
2. One rescuer should begin chest compressions at a depth of at least 5 cm and a rate of 100 compressions per minute. The proper hand position is on the sternum between the T4 and T9 vertebrae.
3. The second rescuer should prepare to give rescue breaths, applying a barrier device if available.
4. After every 30 compressions, the second rescuer provides 2 breaths, ensuring the airway is open and the chest rises with each breath.
5. Rescuers should switch roles approximately every 2 minutes to prevent fatigue.
6. Continue CPR until advanced life support takes over, the victim shows signs of life, or the scene becomes unsafe.

Proper training and technique in CPR are critical to prevent harm, such as broken ribs or damage to internal organs. Rescue techniques and immediate CPR are essential for increasing the chances of survival in cardiac arrest situations, particularly when the victim is retrieved with an airway still sealed.
