Question

1 you are alone caring for a 4 - month - old infant who has gone into cardiac arrest. which is the most effective cpr technique to perform until help arrives? select the correct answer to this question. standing to the side of the infant, provide hands - only cpr. standing to the side of the infant, provide chest compressions using the two - finger technique and deliver ventilations with a bvm. standing or kneeling at the side of the infant with your hips at a slight angle, provide chest compressions using the encircling thumbs technique and deliver ventilations with a pocket mask or face shield. standing to the side of the infant, provide chest compressions using the two - hand technique and deliver ventilations with a pocket mask or face shield.

Explanation:

For a 4 - month - old infant in cardiac arrest when alone, the encircling thumbs technique for chest compressions and using a pocket mask or face shield for ventilations is recommended as it can provide effective compressions and ventilations. Hands - only CPR is not sufficient as infants need ventilations too. The two - finger technique is less effective than the encircling thumbs for generating sufficient pressure. The two - hand technique is not appropriate for an infant's small chest. Using a BVM (Bag - Valve - Mask) alone when alone may be difficult to manage for both compressions and ventilations.

Answer:

Standing or kneeling at the side of the infant with your hips at a slight angle, provide chest compressions using the encircling thumbs technique and deliver ventilations with a pocket mask or face shield.
