Final answer:
Providers giving chest compressions during CPR on an infant should switch every 2 minutes to maintain compression quality and prevent fatigue.
Step-by-step explanation:
The rescuer providing chest compressions should switch roles with another provider every 2 minutes when performing CPR on an infant. This practice is important to maintain the quality and effectiveness of compressions and to prevent rescuer fatigue. The technique for delivering chest compressions involves applying pressure on the sternum, specifically between the T4 and T9 vertebrae, to manually compress the blood within the heart to maintain circulation, particularly critical for the brain. Current standards recommend a depth of at least 5 cm and a rate of 100 compressions per minute. CPR should be performed by individuals who are properly trained to avoid potential injuries to the patient, and proper hand placement is crucial for the technique to be effective.
