Presentation Summary : How fast?Hypovolemic shock. Distributive 3. Shock and hypotension often co-exist, BUT a normal blood pressure DOES NOT exclude the diagnosis of shock. Obstructive It's also possible to have a combination of these. Tachyarrhythmia (usually >> 150 b/m) Bradyarrhythmia (usually < 45 b/m) Hypovolemic shock. See our User Agreement and Privacy Policy. CLASSIFICATION of shock Hematogenic / hypovolemic shock Septic shock Cardiogenic shock Traumatic shock Neurogenic shock Miscellaneous shock (anaphylactic shock, insulin shock etc) Objectives ; The resident will ; Identify the various classifications of shock. Previously, the systemic inflammatory response syndrome (SIRS) criteria were important in identifying patients with sepsis/septic shock. Cardiogenic shock is the inability of the heart to pump blood throughout the body. The third main classification is distributive shock, which includes subclassifications of neurogenic, anaphylactic, and septic shock. Surviving Sepsis Campaign: international guidelines for management of sepsis and septic shock 2016. 1 bolus 10 ml/kg (max. in cyanide poisoning The mnemonic acronym for these four categories is HASH. 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.

Shock is classified according to the causes to three classes: Hypovolemic shock Distributive shock Cardiogenic shock Causes of Shock. Hypovolemic (e.g., vomiting, diarrhea, over-diuresis, post-ATN or post-obstructive polyuria). DEPT OF ORAL & MAXILLOFACIAL Circulatory shock, commonly known simply as shock, is a life-threatening medical condition that occurs due to the provision of inadequate substrates for cellular respiration.Typical symptoms of shock include elevated but weak heart rate, low blood pressure, and poor organ function, typically observed as low urine output, confusion, or loss of consciousness. Medical Shock is defined as a decrease in blood pressure. Shock, in physiology, failure of the circulatory system to supply sufficient blood to peripheral tissues to meet basic metabolic requirements for oxygen and nutrients and the incomplete removal of metabolic wastes from the affected tissues. ¾. Hypovolemic – loss of preload. Arrhythmic shock. Obstructive Shock . Hemorrhagic deaths typically occur very early, usually within the first 6 h of admission, and early hypo perfusion or shock has been demonstrated to promote coagulopathy (1). Predicting blood loss in percent is really important to determine treatments of patients with traumatic injury, which can cause to death by hypovolemic hemorrhagic shock. Shock is classified as, hypovolaemic, cardiogenic, obstructive or distributive, and has been defined as a pathophysiological state in which there is an inadequate A few additional classifications are.

DKA. Tension pneumo, cardiac tamponade. In the United States, this is the leading cause of noncardiac death in intensive care units (ICUs). Etiology Shock can be hypovolemic, cardiogenic or dis-tributive and further classification is based on the etiology (Table 1). Examples include congestive heart failure in dogs and humans. Septic shock is the most common form of distributive shock and is characterized by considerable mortality (treated, around 30%; untreated, probably >80%). New definitions for sepsis and septic shock (Third International Consensus Definitions for Sepsis and Septic Shock [Sepsis-3]) have been developed.

Class: Blood Loss% Clinical Picture: I: 15%: Normal pulse & blood pressure. 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. HAEMORRHAGIC SHOCK. Clinical Signs of Shock . The classification of shock states is traditionally driven by typical haemodynamic assessment. Neurogenic Shock occurs when there’s an uneven blood distribution throughout the body. The accumulation of blood outside the heart, but inside the sac of the heart, known as tamponade, is an example.
