Signs of death or strong indications that a human is no longer alive are: Respiratory arrest (no breathing); Cardiac arrest (no pulse); Brain death (no neuronal activity); The heart and lungs are vital organs for human life due to their ability to properly oxygenate human blood (lungs) and distribute this blood to all vital organs (heart).
Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. [1] It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. The term is also sometimes used in resuscitation research.
The symptoms of a subdural hematoma have a slower onset than those of epidural hematomas because the lower-pressure veins involved bleed more slowly than arteries. Signs and symptoms of acute hematomas may appear in minutes, if not immediately, [ 5 ] but can also be delayed as much as two weeks. [ 6 ]
This increased pressure reduces venous return, thereby reducing lung-heart function, resulting in signs and symptoms of shock. [15] Many of the signs of obstructive shock are similar to cardiogenic shock, although treatments differ. Symptoms of obstructive shock include: Abnormal heart rhythms, often a fast heart rate. Reduced blood pressure.
Oxygen-poor blood enters the right side of the heart through two large veins. Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
