Question

Good CPR can provide _% of normal cardiac output

Answer 1

Good CPR can provide approximately 30% to 40% of normal cardiac output, which is vital in maintaining blood flow to the brain and other vital tissues when the heart stops beating.

Step-by-step explanation:

Good Cardiopulmonary Resuscitation (CPR) is an essential emergency technique used when a patient's heart stops beating. It involves compressing the chest by applying pressure with the flat portion of one hand on the sternum between the lines at T4 and T9. While CPR is not a substitute for the heart's natural function, it can provide approximately 30% to 40% of normal cardiac output. This is critical to maintain blood flow, especially to the brain, preventing irreversible damage and death of neurons. The current standards recommend a chest compression depth of at least 5 cm and a rate of 100 compressions per minute. The target rate can be remembered by keeping pace with the song "Staying Alive" by the Bee Gees.

Answer 2

Good CPR can provide approximately 30-40% of normal cardiac output, which is critical to maintain blood flow, especially to the brain to prevent damage. Hands are correctly positioned on the sternum between T4 and T9, and the recommended compression rate is 100 compressions per minute.

Step-by-step explanation:

Good cardiopulmonary resuscitation (CPR) can provide approximately 30-40% of normal cardiac output. During a CPR procedure, the hands are placed on the sternum between the T4 and T9 vertebrae to manually compress the blood within the heart, pushing it into the pulmonary and systemic circuits. This compression depth and rate, typically at least 5 cm deep and at a rate of 100 compressions per minute, are crucial for maintaining blood flow to the brain and preventing irreversible damage that can occur within minutes of the heart stopping. CPR is an emergency measure to sustain life until the heart begins to beat spontaneously again or until the patient can receive more advanced medical care.
