What are the types and causes of circulatory shock?

There are four subtypes of shock with differing underlying causes and symptoms: hypovolemic, cardiogenic, obstructive, and distributive. Distributive shock can be further divided into septic, anaphylaxis, and neurogenic shock.

What is circulatory shock quizlet?

Circulatory shock is an inadequate blood flow throughout the body, to the extent that the body tissues are damaged. … From a clinical perspective circulatory shock is manifest when organ hypoperfusion alters mental status, cool clammy extremities, decreased blood pressure, decreased pulse rate and oliguria.

What are symptoms of circulatory shock?


What is a shock?

Shock is a critical condition brought on by the sudden drop in blood flow through the body. Shock may result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns or other causes. When a person is in shock, his or her organs aren’t getting enough blood or oxygen.

What is the effect of circulatory shock on blood flow and pressure?

Distributive shock Excessive dilation of blood vessels (vasodilation) increases the capacity of blood vessels and decreases blood pressure. This can decrease blood flow and oxygen delivery to organs. The mechanisms by which these conditions cause vasodilation vary.

What are the type of shock?

There are several types of shock: septic shock caused by bacteria, anaphylactic shock caused by hypersensitivity or allergic reaction, cardiogenic shock from heart damage, hypovolemic shock from blood or fluid loss, and neurogenic shock from spinal cord trauma. Treatment for shock depends on the cause.

What are the stages of circulatory shock?

There are four stages of cardiogenic shock: initial, compensatory, progressive, and refractory. During the initial stage, there is diminished cardiac output without any clinical symptoms.

What is it like to be in shock?

The symptoms of shock include cold and sweaty skin that may be pale or gray, weak but rapid pulse, irritability, thirst, irregular breathing, dizziness, profuse sweating, fatigue, dilated pupils, lackluster eyes, anxiety, confusion, nausea, and reduced urine flow. If untreated, shock is usually fatal.

Why does neurogenic vasogenic shock result from systemic vasodilation?

Neurogenic shock classically occurs in cases of trauma involving the cervical spinal cord. The sympathetic nervous system is damaged resulting in a decreased adrenergic input to the blood vessels and heart, causing vasodilation with resultant hypotension and paradoxical bradycardia.

Why are septic emboli a common complication of infective endocarditis?

Infective endocarditis is an established common cause of septic emboli from case studies as early as 1883. [3] Parts of the vegetations on the valves infected dislodge and travel through the bloodstream and block blood vessels based on the size and the location.

When the blood pressure of a vessel drops below the critical closing pressure for that vessel?

When the blood pressure of a vessel drops below the critical closing pressure for that vessel, the vessel collapses. Which type of capillaries have large fenestrae and are found in endocrine glands? capillaries.

What are the 3 stages of shock?

The three phases of shock: Irreversible, compensated, and decompsated shock

What does it mean if you feel a shock in your heart?

Cardiogenic shock occurs when a weakened heart is suddenly unable to pump enough blood. Shock means that not enough blood and oxygen are reaching the brain and other organs. The most common cause of cardiogenic shock is a severe heart attack (myocardial infarction).

What causes septic shock?

Septic shock is a life-threatening condition that happens when your blood pressure drops to a dangerously low level after an infection. Any type of bacteria can cause the infection. Fungi such as candida and viruses can also be a cause, although this is rare. At first the infection can lead to a reaction called sepsis.

What are the four stages of shock?

It covers the four stages of shock. They include the initial stage, the compensatory stage, the progressive stage, and the refractory stage.

What is shock Slideshare?

DEFINITION  Shock is a life threatening situation due to poor tissue perfusion with impaired cellular metabolism, manifested in turn by serious pathophysiological abnormalities. (

How do you remember shock types?

RNCHAMPS (pronounced R, N, champs) is a mnemonic acronym used to recall the types of shock. The mnemonic is alternately known as CRAMPS NH (Cramps, New Hampshire) or NH-CRAMPS (New Hampshire cramps).

How does shock affect circulation?

Whatever the central physiological mechanism, the effect of shock is to reduce blood flow through the small vessels, or capillaries, where oxygen and nutrients pass into the tissues and wastes are collected for removal.

What happens in response to circulatory shock?

The cardiovascular system responds to hypotension and hypovolemic shock by increasing the heart rate, increasing myocardial contractility and constricting peripheral blood vessels as result of the direct stimulation via the sympathetic system on heart and vessels by the cardiac and vasomotor centers in the reticular …

What happens to blood pressure during shock?

Shock is a defence response This is called vasoconstriction and it helps conserve blood flow to the vital organs. But the body also releases the hormone (chemical) adrenaline and this can reverse the body’s initial response. When this happens, the blood pressure drops, which can be fatal.

What are the 8 types of shock?

18.9A: Types of Shock

What is shock types and management?

The main types of shock are hypovolemic, cardiogenic, and distributive shock. Shock must be managed rapidly by identifying and treating acute, reversible causes; restoring intravascular volume; infusing vasoactive drugs; using mechanical adjuncts, when applicable; and supporting vital functions until recovery.

How do you code circulatory shock?

Circulatory shock, commonly known as shock, is a life-threatening medical condition of low blood perfusion to tissues resulting in cellular injury and inadequate tissue function. … The ICD code R57 is used to code Shock (circulatory)

Specialty: Cardiology, Critical Care Medicine
MeSH Code: D012769
ICD 9 Code: 785.50

What is circulatory shock List the five types of circulatory shock?

Shock (circulatory)

Types Low volume, cardiogenic, obstructive, distributive
Causes Low volume: Bleeding, vomiting, pancreatitis Cardiogenic: heart attack, cardiac contusion Obstructive: Cardiac tamponade, tension pneumothorax Distributive: Sepsis, spinal cord injury, certain overdoses

Why does vasodilation occur in shock?

When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen won’t be pushed to reach the body’s organs.

Do you feel pain in shock?

Why do you feel pain? When you have a shock reaction, you’ll typically unconsciously tense your muscles, ready to fight or flee. You don’t notice the pain of this when you’re in the midst of an adrenalin surge, but as the surge is wearing off, some pain sensations from doing that may emerge.
