Presentation Summary : How fast?Hypovolemic shock. Left untreated, it can cause permanent damage to organs or even death. … Cardiogenic shock (CS) accounts for 15% of all admissions to cardiac intensive care units, with acute myocardial infarction cardiogenic shock (AMICS) accounting for 30% of these. See our User Agreement and Privacy Policy. Shock is classified as, hypovolaemic, cardiogenic, obstructive or distributive, and has been defined as a pathophysiological state in which there is an inadequate supply or inappropriate use of metabolic substrate (particularly oxygen) by peripheral tissues.1 Hypovolaemic and cardiogenic shock will be discussed in this section. Classification of Haemorrhage. Anaemicthe blood is exposed to enough oxygen, but there is not enough hemoglobin to carry the oxygen Stagnant:the blood is well oxygenated, but the circulation is slow, and the oxygen isn’t getting to the tissues- eg. Normal blood volume is 5 L and by losing 1-2 L it can lead to shock. Shock is a life-threatening, generalised form of acute circulatory failure with inadequate oxygen delivery to, and consequently oxygen utilisation by, the cells. There are many types of shock.

CLASSIFICATION of shock Hematogenic / hypovolemic shock Septic shock Cardiogenic shock Traumatic shock Neurogenic shock Miscellaneous shock (anaphylactic shock, insulin shock etc) Shock is identified in most patients by hypotension and inadequate organ perfusion, which may be caused by either low cardiac output or low systemic vascular resistance. In considering the information in this pa per, it is important to remember that not every animal can be saved. Examples include congestive heart failure in dogs and humans. shock and will die, despite the best efforts of the carer and veterinarian. This type of shock is known as physiological shock and can result in collapse, coma or even death if it is not treated immediately. Cardiogenic 3. Clinical classification Clinically, it is common to subdivide shock into cardiogenic, obstructive, hypovolaemic or distributive causes. Severe drop in blood pressure. References. The treatment of shock includes the administration of endogenous catecholamines (epinephrine, norepinephrine, and dopamine) as well as various vasopressor agents that have shown efficacy in the treatment of the various types of shock… cardiogenic shock Histotoxic:the cells receive plenty of oxygen, but are unable to utilize it, eg.

Stage A is “at risk” for cardiogenic shock, stage B is “beginning” shock, stage C is “classic” cardiogenic shock, stage D is “deteriorating”, and E is “extremis”. A few additional classifications are. Surviving Sepsis Campaign: international guidelines for management of sepsis and septic shock 2016. For example, septic shock is an infection that results in dehydration(hypovolemic) and blood vessel dilation (distributive). 1. Vasogenic/ Distributive: includes neurogenic, anaphylactic and septic shock Shock is a dynamic process, and more than one classification can contribute at any one time. Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Hypovolemic shock occurs when the total volume of blood in the body drops below normal such as severe external or internal bleeding, dehydration, diabetes insipidus, kidney failure, extensive burns, or inflammation of the pancreas.

Besides an electrical shock (used to restart the heart) and a term for an extremely emotional state of mind (similar to post traumatic stress disorder), shock also refers to a condition where the body is unable to get enough oxygen and nutrients to important organs and systems. Hemorrhagic shock occurs as a result of hemorrhage due to physical trauma – e.g. A system describing stages of cardiogenic shock from A to E was developed. Common triggers are medications such as penicillin, latex, bee stings, and foods such as nuts or shellfish. Hemorrhagic shock is a condition of reduced tissue perfusion, resulting in the inadequate delivery of oxygen and nutrients that are necessary for cellular function.
