Final answer:
To increase chest compression fraction, perform high-quality chest compressions at a depth of at least 5 cm and a rate of 100 per minute with minimal interruptions. Hand placement on the sternum between T4 and T9 lines is critical for effective circulation.
Step-by-step explanation:
To increase the chest compression fraction (CCF), one needs to focus on performing continuous, high-quality chest compressions with minimal interruptions. The current guidelines recommend compressing the chest at least 5 cm deep and at a rate of 100 compressions per minute, which aligns with the beat of the song "Staying Alive" by the Bee Gees. Proper hand placement is crucial, and hands should be positioned on the sternum between the lines at T4 and T9 to effectively compress the blood within the heart, assisting its flow into the pulmonary and systemic circuits. High-quality CPR is emphasized over artificial respiration, and it should continue until the patient shows spontaneous heart activity or is declared deceased by a healthcare professional.
