Loss of pulse in a person is a direct manifestation of cardiac arrest, marking the termination of blood circulation. Under normal circumstances, once the heart stops beating, blood circulation ceases immediately, leading to a rapid loss of oxygen and nutrient supply to the brain and other vital organs. Generally, if cardiopulmonary resuscitation (CPR) or other emergency measures are not promptly taken to restore the heartbeat within several minutes, the brain will suffer irreversible damage due to lack of oxygen, eventually leading to brain death. Although the exact time of death may vary among individuals, generally speaking, without timely medical intervention after loss of pulse, most individuals will reach the end of life within several minutes to several hours.
