What immediate treatment is necessary for a cardiac arrest patient as part of CPR?

The immediate treatment necessary for a patient experiencing cardiac arrest as part of cardiopulmonary resuscitation (CPR) is chest compressions. Chest compressions play a crucial role in maintaining blood circulation during cardiac arrest, as the heart is unable to pump blood effectively at this time. By performing high-quality chest compressions, rescuers help to ensure that oxygenated blood reaches vital organs, particularly the brain and heart, increasing the chances of survival and recovery.

Starting chest compressions immediately after confirming cardiac arrest is critical because every second counts. The guidelines emphasize the importance of activating emergency medical services while initiating compressions to provide the best possible outcome for the patient. Once a defibrillator (AED) is available, it can be used in conjunction with chest compressions, but the initial and ongoing action in CPR should focus on high-quality chest compressions to maintain blood circulation until advanced care is available.
