What type of shock is hypotensive?
Causes of hypotension Cardiogenic shock occurs when the heart is unable to pump enough blood to meet the body’s demand for oxygen. The number one cause of cardiogenic shock is acute myocardial infarction (MI).
What is compensated shock?
Compensated shock is the phase of shock in which the body is still able to compensate for absolute or relative fluid loss.
What are the common signs of compensated shock?
Compensated Shock Symptoms
- Cool extremities.
- Weak thready peripheral pulse.
- Delayed capillary refill.
- Tachycardia in the absence of fever.
- Narrowing pulse pressure (PP)
What are the 4 types of shock?
The main types of shock include:
- Cardiogenic shock (due to heart problems)
- Hypovolemic shock (caused by too little blood volume)
- Anaphylactic shock (caused by allergic reaction)
- Septic shock (due to infections)
- Neurogenic shock (caused by damage to the nervous system)
What are the three types of distributive shock?
Distributive shock The three subtypes are septic, anaphylactic/anaphylactoid, and neurogenic shock.
What is the difference between compensated and uncompensated shock?
Compensated shock: Category of shock that occurs early, while the body is still able to compensate for a shortfall in one or more of the three areas of perfusion. Uncompensated shock: Category of shock that occurs when the compensatory mechanisms fail and the patient’s condition deteriorates.
What causes compensated shock?
Epinephrine increases heart rate, makes the heart beat harder and constricts the blood vessels. This allows the body to maintain blood pressure and vital organ perfusion. This early stage of shock is called compensated shock.
How does a child’s body usually compensate when in compensated shock?
Importantly, the body will attempt to compensate for shock through various mechanisms, most commonly through increased heart rate. The heart rate will increase in an attempt to increase cardiac output (stroke volume x heart rate).
What is the difference between compensated and decompensated shock?
With compensated shock, the body is able to take measures to maintain blood pressure, however as shock worsens, the body becomes unable to keep up. At this point, perfusion of vital organs is no longer maintained. Symptoms of decompensated shock include: Falling blood pressure (systolic of 90 mmHg or lower with adults)
Does shock cause vasodilation or vasoconstriction?
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….

Which type of shock is most associated with a hyperdynamic cardiac output?
Types of shock Shock is a clinical syndrome characterized by inadequate tissue perfusion that results in end-organ dysfunction. It can be divided into the following four categories: Distributive shock (vasodilation), which is a hyperdynamic process.
What is the definition of a compensated shock?
Compensated shock can be defined as a shock state that has all the signs and symptoms of shock except for hypotension. When the child develops hypotension, it means that he or she has presented late to the emergency department and urgent intervention is needed.
What are the clinical aspects of shock syndromes?
The clinical aspects of shock syndromes are described from their inception as compensated physiology to a stage of decompensation. The clinical significance of hypotension, fluid-responsive and non fluid-responsive hypotension, is discussed.
What is the difference between shock and perfusion?
Shock is an acute or hyperacute physiological derangement, a systemic syndrome characterized by signs and symptoms, which are the response of different organs to a situation of hypoperfusion for their cells basic metabolic needs. Perfusion means oxygen and nutrients delivery via blood flow.
When does a person transition to decompensated shock?
Sometimes, shock is difficult to identify in its early phases and the patient can transition into decompensated shock before you realize. Sometimes that transition occurs prior to our arrival to the scene.
