- Cardiogenic shock is a clinical condition of inadequate tissue (end-organ) perfusion due to the inability of the heart to pump an adequate amount of blood. The reduction in tissue perfusion results in decreased oxygen and nutrient delivery to the tissues and, if prolonged, potentially end-organ damage and multi-system failure.

Background Hypovolemic shock refers to a medical or surgical condition in which rapid fluid loss results in multiple organ failure due to inadequate circulating volume and subsequent inadequate perfusion.Most often, hypovolemic shock is secondary to rapid blood loss (hemorrhagic shock).ypovolemic shock refers to a medical or surgical condition in which rapid fluid loss results in multiple organ failure due to inadequate circulating volume and subsequent inadequate perfusion.

Definition of Shock shock is. A complex clinical syndrome of decreasing blood flow to body tissues resulting in cellular dysfunction, decreased cellular metabolism and eventual organ failure. Shock begins as a cellular phenomenon, it progresses to dysfunction of multiple organ systems.

- The medical term shock refers to a state in which not enough blood and oxygen reach important organs in the body, such as the brain and kidneys. Shock causes very low blood pressure and may be life threatening. Shock can have many causes. Cardiogenic shock is only one type of shock. Other types of shock include hypovolemic (hy-po-vo-LEE-mik) shock and vasodilatory (VAZ-oh-DILE-ah-tor-e) shock. Hypovolemic shock is a condition in which the heart can’t pump enough blood to the body because of severe blood loss. In vasodilatory shock, the blood vessels suddenly relax. When the blood vessels are too relaxed, blood pressure drops and blood flow becomes very low.

What Is Shock? Question: I've heard the term shock a million times, but I realized that I don't really know what it means. What is shock? Answer: Shock is a condition in which blood pressure is too low and not enough oxygenated blood can sustain your body. The medical disorder of shock is not the shock that people feel from a sudden traumatic event. In the United States, hospital emergency departments report more than one million cases of shock each year.

Shock Due to Heart Failure in Dogs Most causative conditions for cardiogenic shock are associated with markedly depressed left or right ventricle function, but other conditions that can cause cardiac compression and lead to inadequate filling of the ventricles may also play a role.

A basic overview of shock Causes and symptoms. Shock is caused by three major categories of problems: cardiogenic (meaning problems associated with the heart's functioning); hypovolemic (meaning that the total volume of blood available to circulate is low); and septic shock (caused by overwhelming infection, usually by bacteria).

secondary shock secondary shock. a state of physical collapse and prostration caused by numerous traumatic and pathological conditions. It develops over time after severe tissue damage and may merge with primary shock, accompanied by various signs, such as weakness, restlessness, low body temperature, low blood pressure, cold sweat, and reduced urinary output.

- Shock: In medicine, a critical condition that is brought on by a sudden drop in blood flow through the body. The circulatory system fails to maintain adequate blood flow, sharply curtailing the delivery of oxygen and nutrients to vital organs.

Dehydrating Vegetables Place on the dehydrator tray in a single layer and dehydrate at 125° for six to eight hours until dry and leathery. Mushrooms absorb flavors well. To make savory mushrooms, heat 1 cup of water with a ½ cube of beef or vegetable bouillon in a pan.Bring to a boil and then remove from heat.ash and dry green beans. Cut off the ends and cut beans into ½ inch to 1 inch lengths. Steaming for eight minutes before drying improves tenderness of the beans on the trail if you cook over candles or in a freezer bag. Spread in a single layer on dehydrator tray and dry at 125° for approximately eight hours.

Shock Physiological shock may be defined as acute progressive circulatory failure, in which the tissues receive an inadequate supply of blood and its components (such as nutrients and oxygen) and an inadequate removal of wastes. The result is cell damage and, eventually, cell death.

- Electrical Cardioversion (Defibrillation) for a Fast Heart Rate. Guide. Electrical cardioversion is a procedure in which a brief electric shock is given to the heart to reset the heart rhythm back to its normal, regular pattern (normal sinus rhythm). The shock is given through paddles or patches applied to the outside of the chest wall. Usually, the person is sedated.

Neurogenic Shock Neurogenic Shock. Neurogenic shock is a type of shock caused by the sudden loss of the autonomic nervous system signals to the smooth muscle in vessel walls. This results in loss of background sympathetic stimulation, which is responsible for maintenence of tone of blood vessels.

- The first goal of emergency treatment for cardiogenic shock is to improve the flow of blood and oxygen to the body’s organs. Sometimes both the shock and its cause are treated at the same time. For example, doctors may quickly open a blocked blood vessel that's damaging the heart.

Cardioversion Synchronized cardioversion is shock delivery that is timed with the QRS complex. This synchronization avoids shock delivery during the relative refractory portion of the cardiac cycle, when a shock could produce ventricular fibrillation. The shock dose used for a synchronized shock is lower than that used for defibrillation.

Shock Shock is a life-threatening condition that occurs when the body is not getting enough blood flow. Lack of blood flow means that the cells and organs do not get enough oxygen and nutrients to function properly. Many organs can be damaged as a result. Shock requires immediate treatment and can get worse very rapidly. As many 1 in 5 people who suffer shock will die from it.

Cardiac tamponade Cardiac tamponade, also known as pericardial tamponade, is when fluid in the pericardium (the sac around the heart) builds up and results in compression of the heart. Onset may be rapid or more gradual. Symptoms typically include those of cardiogenic shock including shortness of breath, weakness, lightheadedness, and cough.

Prevention and Therapies Cardioversion is the use of a defibrillator when a person is not in cardiac arrest but has an abnormal heart rhythm. Sometimes the team will try to shock a heart back into a normal rhythm. The patient will be given sedatives and pain relief before undergoing cardioversion.

- Freebase(0.00 / 0 votes)Rate this definition: Cardiogenic shock is based upon an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively. Since this is a type of shock there is insufficient perfusion of tissue to meet the required demands for oxygen and nutrients.

endotoxic shock endotoxic shock. Septic shock due to release of endotoxins by gram-negative bacteria. Endotoxins are lipopolysaccharides in the cell walls that are released during both reproduction and destruction of the bacteria.

Hypotension, Hypovolemia, and Septic Shock * Shock is characterized by a severe disturbance of the systemic circulation and leads to tissue hypoxia and eventually tissue ischemia. Shock is often reflected by hypotension and hypovolemia, depending on its etiology, which leads to complex reactions of the neuroendocrine and immune systems in order to achieve homeostasis. Specific treatment may be targeted at these regulatory systems.

A basic overview of shock Definition. 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.hock is a medical emergency in which the organs and tissues of the body are not receiving an adequate flow of blood.

Septic shock Septic shock can be defined as sepsis-induced hypotension that persists despite treatment with intravenous fluids. Low blood pressure reduces tissue perfusion pressure, causing the tissue hypoxia that is characteristic of shock.
