Chest Compressions and Cardiac Resuscitation Flashcards

At what heart rate should chest compressions be initiated in a newborn?

Answer: Below 60 bpm after 30 seconds of effective PPV

Chest compressions are started when the heart rate remains below 60 bpm after at least 30 seconds of effective PPV.

What is the compression-to-ventilation ratio used during neonatal resuscitation?

Answer: 3:1

NRP uses a 3:1 compression-to-ventilation ratio, providing 90 compressions and 30 breaths per minute.

What is the preferred technique for chest compressions during neonatal resuscitation?

Answer: Two-thumb encircling technique

The two-thumb encircling technique generates higher peak systolic pressures and is preferred over the two-finger technique.

How deep should sternal compressions be in a newborn?

Answer: One-third the anterior-posterior diameter of the chest

Compressions should depress the sternum approximately one-third the anterior-posterior (AP) diameter of the chest.

Where exactly should the thumbs be placed for the two-thumb encircling technique?

Answer: Lower third of the sternum, just below the nipple line

The thumbs are placed on the lower third of the sternum, just below an imaginary line drawn between the nipples.

When chest compressions are being performed, what oxygen concentration should be used for PPV?

Answer: 100% oxygen

When chest compressions are required, FiO₂ should be increased to 100% to maximize oxygen delivery during cardiac arrest.
