1
Q

Circulation of blood within an organ

A

perfusioin

2
Q

State of collapse and failure of cardiovascular system.

A

shock (hypoperfusioin)

3
Q

A balance of all systems in the body.

A

homeostasis

4
Q

Responsible for formation of blood clots.

A

platelets

5
Q

Three basic causes of shock.

A
Pump failure (heart attack, trauma to heart, obstructive causes)
Low fluid volume (trauma to vessels, fluid loss from GI tract)
Poor vessel function (infection, drug overdose, spinal injury, anaphylaxis)
6
Q

Cardiogenic shock.

A

Pump failure
inadequate circulation results in pulmonary edema which leads to impaired ventilation which leads to increased breathing rate and abnormal breath sounds

7
Q

Widespread dilation of small arterioles, small venules, or both.

A

Distributive shock includes:
Septic shock (from toxins generated in severe infection)
Neurogenic shock (spinal injury, esp. upper cervical)
Anaphylactic shock
Psycogenic shock (usually temporary from syncope)
Hypovolemic shock (hemorrhagic or dehydration)

8
Q

Presence of jugular vein distention, muffled heard sounds and systolic and diastolic blood pressure starting to merge.

A

Beck’s Triad
s/s obstructive shock
mechanical obstruction of heart muscle
Associated with acute cardiac tamponade
