What effect does inadequate blood pressure during CPR have on the resuscitation process?

Inadequate blood pressure during CPR profoundly affects the resuscitation process by inhibiting organ perfusion. When effective chest compressions are not producing sufficient blood pressure, vital organs such as the heart and brain do not receive the oxygen and nutrients they require to function effectively. This lack of adequate perfusion can lead to irreversible damage to these organs, making it more challenging to restore a normal heart rhythm and establish a sustainable return of spontaneous circulation (ROSC). The ultimate goal of CPR is to maintain some level of organ perfusion to preserve these critical tissues during the time when normal heart function is absent. Therefore, achieving and maintaining adequate blood pressure is essential to improving the chances of successful resuscitation and recovery.
