stages of shock - ANSWER Initial
Compensatory
Progressive
Refractory

- increase HR and mild vasoconstriction


Stage 2: Compensatory - ANSWER - decrease in blood pressure
- increased lactic acid
- decrease in pH, hyperkalemia
- increased HR, RR, fluid retention
- thirst, decrease pulse pressure


stage 3: progressive - ANSWER - compensatory mechanisms fail
- increased anaerobic metabolism
- altered capillary permeability- fluid leaks into the tissue
causing hypotension
- hypotension, poor O2, tachycardia, cyanosis, hypoxia, acidosis,
tissue death


Stage 4: Refractory - ANSWER - high mortality
- exacerbated anaerobic metabolism
