The 2025 guidelines show us that survival isn't just a medical miracle; it’s a social outcome. It depends on someone being willing to step up, a dispatcher being ready to coach, and a community investing in the right tools.
The RMD Warwick lecture serves as a comprehensive guide for the 2025/6 BLS and AED provider course, focusing on essential life-saving techniques. It outlines a systematic approach to handling cardiac arrest, starting with the initial assessment of a collapsed individual and the immediate notification of emergency services


For a drowning victim, the standard "Compressions-Airway-Breathing" (CAB) sequence is often reversed to "ABC" by trained responders. Because drowning is a hypoxic arrest caused by a lack of oxygen rather than primary heart failure, the protocol recommends starting with five initial rescue breaths before beginning chest compressions. If it is safe and the rescuer is trained, these ventilations can even begin in the water, although compressions must always wait until the victim is on a firm surface.
Agonal gasps are occasional, irregular breaths that can occur shortly after the heart stops, and they are frequently mistaken by laypeople for normal breathing. The 2025 guidelines explicitly state that if a person is unresponsive and only gasping, you must assume they are in cardiac arrest and start CPR immediately. Waiting or double-checking for a pulse for an extended period can delay life-saving intervention.
High-quality compressions require significant physical effort, and rescuer fatigue typically sets in within two minutes, often before the rescuer even realizes their technique is degrading. Leaning on the chest and failing to allow for full recoil prevents the heart from refilling with blood, making the compressions ineffective. Switching roles every two minutes—usually when the AED is analyzing the heart rhythm—ensures that the depth and rate remain within the optimal range for survival.
No, Naloxone is not a substitute for CPR if the victim is in full cardiac arrest. While Naloxone should be administered as soon as possible if an overdose is suspected, it requires blood circulation to reach the brain and take effect. If the patient has no pulse, the priority remains high-quality chest compressions and the use of an AED to keep the person viable while the medication is administered.
According to the 2025/6 protocols, high-quality compressions for an adult must reach a depth of five to six centimeters at a rate of 100 to 120 beats per minute. Rescuers must ensure the chest recoils completely between each push to allow the heart to refill. Furthermore, the "CPR fraction" should be at least 60%, meaning the chest should be compressed for at least 36 seconds out of every minute to maintain the necessary blood pressure to the brain.
