In fluid dynamics, a moving shock is a shock wave that is travelling through a fluid (often gaseous) medium with a velocity relative to the velocity of the fluid already making up the medium. [1] As such, the normal shock relations require modification to calculate the properties before and after the moving shock.
Crush syndrome (also traumatic rhabdomyolysis or Bywaters' syndrome) is a medical condition characterized by major shock and kidney failure after a crushing injury to skeletal muscle.
Shock is a medical emergency and requires urgent medical care. If shock is suspected, emergency help should be called immediately. While waiting for medical care, the individual should be, if safe, laid down (except in cases of suspected head or back injuries). The legs should be raised if possible, and the person should be kept warm.
A Shock Response Spectrum (SRS) [1] is a graphical representation of a shock, or any other transient acceleration input, in terms of how a Single Degree Of Freedom (SDOF) system (like a mass on a spring) would respond to that input. The horizontal axis shows the natural frequency of a hypothetical SDOF, and the vertical axis shows the peak ...
Hypovolemia (Hypovolemic shock) Intravascular volume status Heart rate (Tachycardia) / Systolic blood pressure (Hypotension) / Decreased urine output: Intravenous fluid / Intraosseous infusion / Blood transfusion with packed red blood cells: Cardiogenic shock: Cardiac output: Positive inotropic agents / Chronotropes: Distributive shock: Sepsis ...
Its utility in distinguishing types of shock has been discussed in medical literature and reference material concerning emergency medicine, [1] emergency medical services, [2] fire rescue, [3] and specialized courses such as the Comprehensive Advanced Life Support Program.
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
This type of shock by definition must pass into the body through the skin. Microshock: Very small current source with a pathway directly connected to the heart tissue. The shock is required to be administered from inside the skin, directly to the heart i.e. a pacemaker lead, or a guide wire, conductive catheter etc. connected to a source of ...
