Incorrect. With an advanced airway in place, compressions should continue uninterrupted while providing 10 breaths per minute.

Incorrect. Chest compressions are performed to dislodge the obstruction and restore effective ventilation in an unresponsive infant.

Incorrect. Oxygen saturation should be maintained at 92-96% to prevent hypoxia and avoid the harmful effects of hyperoxia.

Incorrect. Pulse checks are performed every 2 minutes during rhythm assessments to evaluate the effectiveness of resuscitation.

Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.
