Final answer:
If an AED does not advise a shock, it indicates the patient's heart rhythm is not in a shockable state. In such cases, immediately resume CPR with a cycle of 30 chest compressions and 2 rescue breaths. Keep using AED to re-check the heart rhythm after every 2 minutes cycle of CPR, and if it advises a shock, proceed with defibrillation.
Step-by-step explanation:
When the AED (Automated External Defibrillator) analyses the rhythm and does not advise a shock, it means the patient's heart rhythm is not in a life-threatening arrhythmia that can be treated by defibrillation. Hence, as you have already correctly mentioned, the appropriate step is to immediately resume CPR (Cardiopulmonary Resuscitation).
Proceed with 30 chest compressions at a rate of 100-120 compressions per minute, followed by giving 2 rescue breaths. Repeat this cycle of 30 compressions and 2 breaths until there are signs of life, an AED is ready to use again, or medical professionals take over. After each 2-minute session of CPR, use the AED to check the heart rhythm again. If it is still not advising a shock, continue with CPR.
Remember, the goal is to maintain circulation and oxygenation to vital organs, primarily the brain and heart. Use the AED as soon and as often as possible, as the patient’s rhythm can change, and defibrillation may become necessary.
