Cardiopulmonary Resuscitation (CPR) Practice

Question: 1 / 400

What fraction of normal cardiac output is achieved during CPR?

1/4 normal cardiac output

1/3 normal cardiac output

During cardiopulmonary resuscitation (CPR), compressions can generate approximately one-third of normal cardiac output. This fraction is significant because it indicates that while the effectiveness of circulation during CPR is markedly reduced compared to normal conditions, it is still sufficient to provide some level of perfusion to vital organs.

This level of perfusion is crucial as it can help maintain blood flow to the heart and brain, thereby increasing the chances of survival and neurological recovery until advanced medical support can be provided. Understanding this fraction emphasizes the importance of high-quality chest compressions, as they aim to maximize blood flow despite the limitations of the CPR process.
