In medicine shock implies a failure by the circulation to meet the metabolic demand of the tissues. The failure of the circulation is usually, but not always, reflected by hypotension (low blood pressure).
Shock can result from loss of blood or severe fluid losses (hypovolaemia), loss of fluid from the circulating blood volume inside the body (distributive shock), weakness of the heart's contraction (cardiogenic shock) loss of the constrictive tone of the blood vessels (vasodilatory shock) and obstruction of the blood flow (obstructive shock). Often the cause of shock is a mix of more than one of these mechanisms.
Examples of specific causes of shock include: haemorrhage, burns, severe diarrhoea, anaphylaxsis, systemic infection, myocardial infraction, pulmonary embolism and cardiac tamponade.
Untreated persistent clinical shock will progress to multiple organ dysfunction and eventually death.
While anxiety, and psychological distress are symptoms of shock (caused by the activity of the sympathetic nervous system) the medical syndrome of clinical shock is quite distinct from the lay concepts of psychological shock perpetuated by the media.
What else can I help you with?
With a systolic pressure of 80p what class of shock is the victim in?
Class III or IV, depending on other clinical sequela.
Why does the clinical presentation of neurogenic shock differ from that of hypovolemic shock?
Neurogenic shock is characterized by a loss of sympathetic tone due to spinal cord injury, leading to vasodilation, bradycardia, and hypotension, often with warm, dry skin. In contrast, hypovolemic shock results from significant fluid loss, causing tachycardia, cold, clammy skin, and signs of peripheral vasoconstriction as the body attempts to maintain blood flow to vital organs. These differing mechanisms of hemodynamic instability and compensatory responses result in distinct clinical presentations.
What differentiate hemorrhagic shock from neurogenic shock?
Hemorrhagic shock is primarily caused by significant blood loss, leading to inadequate tissue perfusion and oxygenation, which results in organ dysfunction. In contrast, neurogenic shock results from a loss of sympathetic tone, typically due to spinal cord injury or severe trauma, causing vasodilation, hypotension, and bradycardia without significant blood loss. While both conditions lead to hypotension and shock, their underlying mechanisms and clinical presentations differ markedly.
Is dialated pupils a sign of shock?
Dilated pupils can be a sign of shock, as they may indicate a response to stress or a lack of oxygen in the brain. In shock, the body activates the sympathetic nervous system, which can lead to pupil dilation. However, dilated pupils can also result from other factors, such as medications, recreational drugs, or certain medical conditions, so it's important to consider the entire clinical picture.
What is clinical attutude or clinical approach?
A clinical approach involves the use of empirical information and treament.
What is the definition of clinical pharmacology?
Clinical Pharmacology is the application of pharmacological concepts and principles in the clinical setting.
What does shock mean in g-shock?
G= Gravity Shock+Gravity=Gravity shock which means it's shock resistance when dropped.
What are the 4 major types of shock?
The four major types of shock are hypovolemic shock (caused by low blood volume), cardiogenic shock (caused by heart failure), distributive shock (caused by vasodilation), and obstructive shock (caused by an obstruction to blood flow).

What is abbreviation of guideline?
Clinical Practice Guidelines or Clinical Guidelines or Clinical Guidance is commonly abbreviated as CPGs or CGs
