New York State Basic Emergency Medical Technician (EMT-B) Practice Exam

Which technique is preferred for performing chest compressions on an infant by two healthcare providers?

1. One-handed compression technique

2. Two thumb, encircling hands technique

3. Alternate hand technique

4. Single thumb technique

The correct answer is: Two thumb, encircling hands technique

The two thumb, encircling hands technique is the preferred method for performing chest compressions on an infant by two healthcare providers because it provides better support and allows for more effective compressions. This technique involves one provider placing both thumbs on the center of the infant's chest, just below the nipple line, while encircling the infant's body with their fingers. This not only stabilizes the infant but also allows for the application of compressions with the thumbs, which can generate greater force with minimal effort. Using both thumbs together increases the surface area of the compression and allows for deeper, more effective compressions while maintaining the integrity of the infant's airway. The two providers can easily coordinate their efforts, making it easier to maintain the correct depth and rate of compressions while providing optimal care. Other techniques, such as the one-handed compression, alternate hand, or single thumb techniques, may not provide the same level of effectiveness or stability when performing CPR on an infant, which is critical for ensuring the best chance of survival in emergencies.
