Septic shock is caused by

1 of 11
Endotoxins trigger immune and inflammatory responses in
Septicaemia
2 of 11
Bacteria in septic shock can be
Gram negative or positive
3 of 11
Clients at risk are
Immune compromised, hospitalised, chronic illness, poor nutrition

Early stages of septic shock are

Stage 3
Refractory /irreversible
8 of 11
Stage 1
Inadequate oxygen supply to tissue, sustained decrease in MAP
9 of 11
Stage 2 shock
Stage 2 ‐ Intermediate  Sustained decrease in MAP> 20 mmHg  Compensatory mechanisms no longer able to sustain MAP  Vasoconstriction causes cells to die  Anaerobic metabolism  Lactic acidosis  Sodium/Potassium pump fails ‐> impaired contractili

Stage 3 refractory irreversible
Compensatory mechanism overwhelmed  Blood flow to vital organs is critically reduced  Cerebral & myocardial ischaemia is clinically apparent  eg. mental status changes, cardiac rhythm disturbances, decreased cardiac output  Worsening lactic/metab
