What is the primary responsibility of the team member designated as the Compressor during a BLS resuscitation?

In a BLS resuscitation scenario, the Compressor has the critical role of providing high-quality chest compressions. This is fundamental because effective chest compressions help maintain blood circulation by manually pumping the heart, which is essential for delivering oxygen-rich blood to vital organs. Proper compression technique includes allowing full chest recoil after each compression and maintaining a rate of 100 to 120 compressions per minute.

By concentrating on delivering chest compressions, the Compressor effectively supports the primary goal of cardiopulmonary resuscitation (CPR), which is to restore blood flow to the brain and other vital organs until further medical help arrives or the victim shows signs of recovery. Other tasks, such as assessing the patient's condition, operating an AED, or assisting with ventilation, are important but take a secondary role to the primary objective of maintaining circulation through continuous and effective compressions.
