Adult CPR and AED Usage Flashcards

What is a common cause of ineffective compressions that rescuers should avoid?

Answer: Leaning on the chest and preventing full recoil

Leaning on the chest prevents recoil and reduces blood return to the heart.

What should you do if you suspect a head or neck injury but the adult needs rescue breaths?

Answer: Use the jaw-thrust maneuver to open the airway

The jaw-thrust opens the airway without moving the neck when spinal injury is suspected.

How should you open the airway of an adult with no suspected spinal injury?

Answer: Head-tilt, chin-lift maneuver

The head-tilt chin-lift is the standard method to open the airway in most adults.

What is the recommended action if your hands tire and compressions weaken with no second rescuer?

Answer: Continue the best compressions you can until help arrives

Continuous compressions, even if imperfect, are better than stopping entirely.

When should you stop performing CPR on an adult?

Answer: When EMS takes over or the person shows signs of life

Continue CPR until trained help takes over, an AED directs otherwise, or the person revives.

What is the risk of giving rescue breaths too forcefully or too quickly?

Answer: Air can enter the stomach causing vomiting and aspiration

Over-aggressive breaths inflate the stomach, increasing the risk of regurgitation and aspiration.

Why is bystander CPR before EMS arrival so important for survival?

Answer: It can double or triple the chance of survival

Immediate bystander CPR can double or triple survival rates from cardiac arrest.
