A 40 year old female patient presents with excessive bleeding and drowsiness due to a road traffic accident 5 hours ago. General physical examination reveals:
Blood pressure – 80/60 mmHg
Jugular venous pressure – Low
Pulsus paradoxus – Present
Cardiac output – Increased
The patient is in which type of shock?
Distributive Shock

Includes anaphylactic shock, septic shock and spinal cord injury (neurogenic shock).
Inadequate organ perfusion is associated with vascular dilatation and hypotension, low systemic vascular resistance, inadequate afterload and a resulting abnormally high cardiac output.
In anaphylaxis, vasodilatation is due to excess histamine release.
Neurogenic shock is caused by traumatic or pharmacological blockage of the sympathetic nervous system, producing dilatation of resistance arterioles and capacitance veins, leading to relative hypovolemia and hypotension.

In neurogenic shock, because of loss of vascular tone, JVP will fall.
JVP = Jugular venous pressure
