Final answer:
Yes, during CPR, chest compressions pump blood throughout the body to maintain blood flow and oxygenation to critical organs.
Step-by-step explanation:
Yes, chest compressions do pump blood throughout the body during cardiopulmonary resuscitation (CPR). When the heart stops, chest compressions are performed by applying pressure to the sternum, which squeezes the blood within the heart and pushes it into the pulmonary and systemic circuits. This helps maintain blood flow and oxygenation to critical organs, such as the brain. CPR is an essential life-saving technique that should be performed until the patient regains spontaneous contraction or is declared dead by a healthcare professional.
