1. CNS experiences decreased perfusion FIRST
2. restless, agitation/lethargic, confused/unresponsive, coma
4. BP elevated (narrow BP-> normal/slightly ↑SBP but DBP normal
5. SBP lower than 40mmhg
6. doppler or palpation
7. 80, 70, 60
8. weak, thready, Pulse slows in later stages
9. beta blockers, "lol", may not exhibit s/s like anxiety & tachycardia
10. obstructive/cardiogenic shock, hypovolemic
1. Resp. system: early stages of shock
3. most accurate assessment of O2
4. Renal system: what happens to U/O? what is decreased? What is activated? retention and reabsorption? what does U/O assess?
5. initially, BUN is ↑ and creatinine is normal, if hypoperfusion is prolonged what levels increase?
6. GI: slow activity, ↓ sounds, distention, nausea and constipation , movement of microvilli allows bacteria to make pt susceptible to...
7. Hepatic- altered liver enzymes, liver not able to stop invading orgnanisms, produce coag factors or detoxify drugs, what happens?
8. Hematological: coagulopathy , what is seen do to this?
9. Integumentary: what do you see?
1. rapid, deep : to get rid off CO2
2. shallow, poor gas exchange
4. oliguria, GFR, RAAS & renin, water & Na+, renal perfusion
6. infections and sepsis
7. clotting d/os, drug toxicity, ↑ risk for infection
8. petechiae, ecchymosis, blood in urine/stool/secretions
9. cyanosis, : late sign but unreliable
