Q

Frank Starling law/mechanism:

Vascular Resistance:
SVR vs. PVR:
SVR (Systemic Vascular Resistance):
PVR (Pulmonary Vascular Resistance):

A

= more myocardium is stretched the more force/greater the next contraction will be (increase in preload increases contraction)
= Resistance to overcome to push blood through circulatory system
= Body’s circulation resistance & Lung’s circulation resistance
= resistance blood faces in systemic circulation (arteries size)
= resistance blood faces in pulmonic circulation EX CHF, R ventricle

54
Q

Preload:
Afterload:

Mean Arterial Pressure (MAP):

A

= pressure/vol/ w/in ventricles @ end of diastole “End-diastole vol/“
= resistance against which the heart must pump against (increase afterload= increase ventricular workload)
= average pressure in arteries during a single cardiac cycle = pressure that drives blood to tissues (ensuring organ perfusion)

55
Q

Platelet Phase of hemostasis:

A

2nd phase, Platelets aggregate, or collect and adhere. Slows hemorrhage from capillaries and small vessels- splint fractures to decrease of clots being broken down & bleeding again

56
Q

Coagulation Phase of hemostasis:

A

3rd phase Clotting factors activated and released into bloodstream through a very complex cascade of events Triggers series of chemical reactions; formation of strong protein fibers (fibrin)

61
Q

Jacksons Theory) Zone of Hyperemia:

A

surrounding Area of erythema, damage with more RBC coming to area b/c/& cap/s more permeable (increased blood supply) trying to get phagocytes to inside for healing process
Sig burns have sig swelling from shift of fluid

62
Q

Jacksons Theory) Zone of Stasis / “Ischemia”:

A

Less damaged area adjacent to the Zone of Coagulation (treatable & posible reversible damage)

Jacksons Theory of Thermal Burns 3 burn zones:

A

1st Zone of Coagulation 2nd Zone of Stasis 3rd Zone of Hyperemia

122
Q

(Jacksons Theory) Zone of Coagulation:

A

Area of burn nearest to the heat source (most damage & tissue necrosis)Most damaged area

123
Q

Zone of Hyperemia:

A

surrounding Area of erythema, damage with more RBC coming to area b/c/& cap/s more permeable (increased blood supply) trying to get phagocytes to inside for healing process
Sig burns have sig swelling from shift of fluid

124
Q

Zone of Stasis / “Ischemia”:

Less damaged area adjacent to the Zone of Coagulation (treatable & posible reversible damage)

125
Q

Thermal burn phases:

126
Q

(Thermal burn phases) Emergent phase:

A

Vtach, cells anaerobic Body’s initial reaction to burn; pain response (afferent nerves damage> Nor/Epi release > tachycardia ; unless on beta blockers

127
Q

(Thermal burn phases) Fluid-shift phase:

A

2nd phase; can last up to 24 hours; larger than 15 to 20%(BSA) of total body surface area
vasodilates & capillaries more permeable for phagocytosis

128
Q

(Thermal burn phases) Hypermetabolic phase:

A

3rd phase Days or weeks depending on burn severity; increase in body’s demands for nutrients; begins process of repairing damaged tissue (needs Glucose, amino acids, carbohydrates, O2 to support damage)

129
Q

(Thermal burn phases) Resolution phase:

A

4th phase Scar tissue laid down and remodeled; rehabilitate and return to normal function (weeks to months) new collagen & usually doesnt remodel to original state & makes escar (burn keloid) bc overgrowth
