What pressure should compressions generate during CPR?

During CPR, it is essential that chest compressions generate adequate pressure to effectively increase blood flow to vital organs, especially the brain and heart. The proper range of pressure during compressions is crucial because it ensures that blood circulation is maintained despite the absence of a heartbeat.

The recommended pressure during compressions should be within the range of 15-20 mmHg. This pressure allows for sufficient blood return to the heart during the recoil phase of compressions, while also providing enough force to propel blood through the circulatory system during the compressions themselves. Achieving this pressure aids in maintaining vital organ perfusion, which is critical in sustaining life until advanced medical interventions can be administered.

Utilizing lower pressure levels, such as those indicated by the other choices, would likely result in inadequate depth and effectiveness of compressions, compromising the chances of survival and recovery for the patient. Therefore, the correct choice reflects the established guidelines for performing effective CPR with optimal outcomes.
