SHOCK

Question 1

Compensating Shock Formula

Answer 1

HR (increased) x SV = CO (compensated) X PVR (increased)= BP (maintain)

Question 2

Mechanisms that initially offset shock

Answer 2

• Sympathetic Response
• Hormonal Response
• Adrenal Response

Question 3

Sympathetic Response

Answer 3

Increase: HR, CO, Contractility, PVR

Question 4

Hormonal Response

Answer 4

Pituitary Gland -> ADH Secretion ->
Adrenal Gland -> Aldosterone Secretion ->

= Water and sodium retention by kidneys to help replenish plasma volume

Question 5

Adrenal Response

Answer 5

Release of epinephrine -> Further Increase vasoconstriction-> Increase arterial pressure to perfuse heart and brain -> Blood is shunted from muscle, skin, kidney and liver / decrease hydrostatic pressure -> fluid moves from interstitial space to capillary to restore plasmas.

Question 6

Decompensating Shock Formula

Answer 6

HR (increased) x SV (decreased)= CO (decreased) x PVR (increased) = BP (decreased)

Question 7

Irreversible Shock Formula

Answer 7

HR x SV = CO x PVR = BP (all decreased except PVR)
