Final answer:
The correct answer is c) switch the compressor about every 5 minutes. According to the 2015 AHA (American Heart Association) guidelines for CPR, a switch in the compressor is recommended approximately every 2 minutes, rather than every 5 minutes. The other statements provided are all correct.
Step-by-step explanation:
The correct answer is c) switch the compressor about every 5 minutes.
According to the 2015 AHA (American Heart Association) guidelines for CPR, a switch in the compressor is recommended approximately every 2 minutes, rather than every 5 minutes. This is to prevent compressor fatigue and ensure the effectiveness of chest compressions. It is important to have a fresh and capable compressor to maintain the quality and consistency of compressions.
The other statements are all correct. The rate of chest compressions should be between 100 and 120 compressions per minute, with a compression depth of at least 2 inches in adults. A chest compression fraction of at least 60% but ideally greater than 80% refers to the proportion of time during CPR that should be spent on compressions. Allowing complete chest recoil after each compression is also an important aspect of performing high-quality chest compressions.
