Overview Definition. Cardiogenic shock is a condition in which your heart suddenly can't pump enough blood to meet your body's needs. The condition is most often caused by a severe heart attack. Cardiogenic shock is rare, but it's often fatal if not treated immediately. If treated immediately, about half the people who develop the condition survive.

Shock (circulatory) Shock is a life-threatening medical condition of low blood perfusion to tissues resulting in cellular injury and inadequate tissue function. The typical signs of shock are low blood pressure, rapid heart rate, signs of poor end-organ perfusion, and weak pulses. The shock index, defined as heart rate divided by systolic blood pressure, is an accurate diagnostic measure that is more useful than hypotension and tachycardia in isolation. Under normal conditions, a number between 0.5 and 0.8 is typic

body wave n. A seismic wave that travels through the earth rather than across its surface. Body waves usually have smaller amplitudes and shorter wavelengths than surface waves and travel at higher speeds.. A seismic wave that travels through the earth rather than across its surface. Body waves usually have smaller amplitudes and shorter wavelengths than surface waves and travel at higher speeds.

Shock wave Like an ordinary wave, a shock wave carries energy, and can propagate through a medium. It is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium. In supersonic flows, expansion is achieved through an expansion fan. Unlike solitons (another kind of nonlinear wave), the energy of a shock wave dissipates relatively quickly with distance.

Shock Shock is a dangerous physical condition in which the flow of blood throughout the body is drastically reduced, causing weakness, confusion, or loss of consciousness. It can result from many kinds of serious injuries and illnesses. If shock is not treated quickly, a person can suffer permanent organ damage and die.

A basic overview of shock Shock is a medical emergency in which the organs and tissues of the body are not receiving an adequate flow of blood. This deprives the organs and tissues of oxygen (carried in the blood) and allows the buildup of waste products. Shock can result in serious damage or even death.

- Extracorporeal shockwave therapy (ESWT) is a treatment used in physical therapy, orthopedics, urology and cardiology. The shock waves are abrupt, high amplitude pulses of mechanical energy, similar to soundwaves, generated by an electromagnetic coil or a spark in water.

Shock absorber A shock absorber (in reality, a shock damper) is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. A shock absorber is a type of dashpot.

- Electric shock is the physiological reaction, sensation, or injury caused by electric current passing through the (human) body. It occurs upon contact of a (human) body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair. Very small currents can be imperceptible.

Detonation The initial shock wave is visible on the water surface, and a shock condensation cloud is visible overhead. Detonation (from Latin detonare, meaning to thunder down) is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases.

Shock wave In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid it is a shock wave. Like an ordinary wave, a shock wave carries energy, and can propagate through a medium; however it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.
