A

Compensated
Progressive (decompensated)
Irreversible

20
Q

compensated shock

A

Body keeping up, 1st stage

21
Q

Progressive shock

A

Decompensated, progressing to death

No longer keeping up with demand

22
Q

Irreversible shock

A

Even if intervention, enough tissue has died, organism dies,

23

A

CO2

24
Q

Beta 1

A

Increase chron, Inotrope, automaticity

Heart

25
Q

Beta 2

A

(Lungs)

26
Q

Types of shock

A 
Cardiogenic
Hypovolemic 
Distributive 
 Septic
 Anaphylactic 
 Neurogenic
27
Q

Cardiogenic shock
Causes
Signs
Fix

A

Causes: MI, trauma, infection, pericardial
tamponade

Signs: normal BP, narrowing PP, pulmonary edema if not overcoming Afterload

Fix: nitrate-decrease AL, dopamine-inc vent press

28
Q

Hypovolemic shock
Causes
Signs
Fix

A

Classic shock-fluid loss

Causes: hemmhorage, trauma, dehydration, bone fracture, plasma loss, sweating

Signs: AMS, pale (shunt) cool clammy, normal then rapid pulse, normal BP then HTN

Fix: control bleed, airway, bonus crystalline, PSAG

29
Q

Neurogenic shock
Causes
Signs
Fix

A

A form of distributive
Injury to spinal cord
No release of hormones, no responses, warm, no shunt, no change in HR

SIGNs: warm dry skin, low BP, slow pulse

TREAT: airway, immob, temp, IV dopamine, fluid bolus because pipes too big

30
Q

Anaphylactic shock
Causes
Signs
Fix

A

Severe immune response to foreign object-kill invader

SIGNS: inc RR, sneezing, coughing wheezing, skin flush, itchy, hives, swell, cyanosis, Cap leak-rash, bronchoconstrict, inc HR, N/V, cramp, AMS, seizure,

TREAT: airway-ET, IV antihistamines, epi, cort, vasopressors-tighten back, fluids

31
Q

Septic shock
Causes
Signs
Fix

A

Sick, very sick

SIGNS: inc BP, high fever, no fever, hypothermic, skin flushed, pale, cyanotic, diff breath, altered lungs, AMS

TREAT: airway, IV of crystalloid, dopamine to support BP, monitor heart

32
Q

Alpha 2

A

Dec norepi

33
Q

Alpha 1

A

Vasoconstrictor, - chronotrope, + Inotrope

34
Q
