Cardiopulmonary Resuscitation (CPR) Practice 2025 - Free CPR Practice Questions and Study Tips.

Backup assistance should be requested if the situation deteriorates or if the rescuer becomes fatigued. During CPR, maintaining high-quality compressions and ensuring effective ventilations is critical for increasing the chances of survival. If the rescuer notices that the victim's condition worsens, this indicates that the current intervention may not be sufficient, or that additional support could enhance the effectiveness of the resuscitation efforts.

Becoming fatigued is also a significant factor; as fatigue sets in, the quality of CPR can decline, leading to reduced blood flow and oxygen delivery to vital organs for the patient. Requesting backup assistance in such circumstances ensures that there is sufficient manpower to provide continuous and effective resuscitation, thereby improving the victim's chances of survival.

Requesting backup after two minutes of CPR or upon the arrival of a defibrillator, while important in their own right, does not prioritize the immediate need for additional help when encountering signs of deterioration or rescuer fatigue. Similarly, if the victim shows signs of improvement, it may not be necessary to call for backup assistance, as this could indicate that the efforts made are effective.
