what is happening (main body) = patho Flashcards
What is happening Compensating?
Able to maintain adequate perfusion to vital organs = by shunting blood from the periphery = increase HR, + vascular tone.
Normal appearance, tachy, decreased perfusion, (cool extrities), prolonged cap refill.
What is happening in Decomensating
Inadequate perfusion = not able to maintain a normal BP
(Hypotension) = (Late sign =brain, heart, kidneys will shut down)
Tachy = poor peripheral perfusion
Altered appearance = inadequate perfusion of the brain.
Hypovolaemic shock
Loss of fluids
Dehydration, Diarrhoea and burns (most common cause)
Lethargic, tachypnoea, pale, mottled, cyanotic, sunken eyes, dry mucous, delayed cap refill, cool extremities.
Distributive shock
Fluids leaking out of the cappilaries into the tissues
Septic, Anaphylactic, Neurogeni
Decreased vascular tone, vasodilation and 3rd spacing of fluids ( leaking of plasma out of the blood vessels and into the surrounding tissues )
warm flushed skin, bounding pulse due to the vasodidation
Cardiogenic Shock
Direct poisoning of the myocardium
Arrhythmias, Myocardidis, Anything that stuns the heart
lethargic, increased work of breathing (heart failure, pulmonary odeama)
poor circulation (pale, mottled, cyanotic)
abnormal heart rate, clammy
Obstructive Shock
Tension Pneumothorax, Cardiac Tamponade, Aortic Stenosis
