hypovolemic shock ("low tank")
Answer:
A condition in which low blood volume, due to massive internal or external bleeding or
extensive loss of body water, results in inadequate perfusion.
-imagine that the heart is an empty tank.
With less circulating blood volume, preload and stroke volume drops resulting in low cardiac
output. An increase in systemic vascular resistance (SVR), or vascular tone, occurs to maintain
mean arterial pressure (MAP) and perfusion to the vital organs
QUESTION

Answer:
Hypotension, tachycardia
Weak thready pulse
Cool, pale, moist skin
Decreased urinary output (UOP)
QUESTION
hemodynamic pattern in hypovolemic shock
Answer:
Decreased preload
Decreased diastolic filling
Decreased MAP
Decreased cardiac output (CO) Increased SVR
QUESTION
cardiogenic shock ("pump dysfunction")
Answer:
there is a primary failure in the right or left ventricle (pump) resulting in decreased cardiac
output (CO).

QUESTION
obstructive shock
Answer:
Shock that occurs when there is a block to blood flow in the heart or great vessels, causing an
insufficient blood supply to the body's tissues. the heart is functional but there is an obstruction
of outflow.
