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.
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
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.
Blood pressure measurements can be taken to assess for signs of shock; Auscultation of the heart can be undertaken by medical professionals; Observation for secondary signs of circulatory failure such as edema or frothing from the mouth (indicative of congestive heart failure)
An embolus, is described as a free-floating mass, located inside blood vessels that can travel from one site in the blood stream to another. An embolus can be made up of solid (like a blood clot), liquid (like amniotic fluid), or gas (like air). Once these masses get "stuck" in a different blood vessel, it is then known as an "embolism."
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Acute stress reaction, also known as psychological or mental shock Shell shock, soldiers' reaction to battle trauma; Circulatory shock, a medical emergency Cardiogenic shock, resulting from dysfunction of the heart; Distributive shock, resulting from an abnormal distribution of blood flow Septic shock, a result of severe infection
