BLS for Healthcare Providers Flashcards

For an adult in cardiac arrest, what is the recommended chest compression depth?

Answer: At least 2 inches (5 cm) but no more than 2.4 inches (6 cm)

Adult compressions should be at least 2 inches but not exceeding 2.4 inches to maximize perfusion without injury.

What is the target compression rate for high-quality CPR in all age groups?

Answer: 100 to 120 per minute

The recommended compression rate is 100 to 120 per minute for adults, children, and infants.

When performing two-rescuer CPR on a child, what compression-to-ventilation ratio is used?

Answer: 15:2

Two healthcare providers use a 15:2 ratio for infants and children.

Why is full chest recoil important during compressions?

Answer: It allows the heart to refill with blood between compressions

Allowing the chest to fully recoil lets the heart refill, improving cardiac output.

What is the maximum recommended interruption time when pausing compressions to give breaths or analyze rhythm?

Answer: Less than 10 seconds

Interruptions in chest compressions should be limited to less than 10 seconds to maintain perfusion.

During CPR with an advanced airway in place, how should ventilations be delivered?

Answer: 1 breath every 6 seconds without pausing compressions

With an advanced airway, give continuous compressions and 1 breath every 6 seconds (10 breaths per minute).

What should rescuers do to reduce fatigue and maintain compression quality during prolonged CPR?

Answer: Switch compressors about every 2 minutes

Rescuers should switch roles roughly every 2 minutes to prevent fatigue-related decline in quality.
