haemodynamic disorders Flashcards
shock: define shock and identify possible causes and mechanisms
5 types of shock
hypovolaemic, cardiogenic, anaphylactic, septic, neurogenic
contributors to shock
burns, sepsis, myocardial infarction, hypokalaemia, pulmonary embolism
define hypovolaemic shock
> 1L loss of blood
which areas are affected by hypovolaemic shock
kidney, brain, skin
define cardiogenic shock
where blood demand is greater than the heart’s ability to supply
example of cardiogenic shock
myocardial infarction
features of systemic inflammatory response syndrome
temperature below 36C or above 38C, tachycardia, high respiratory rate, high white blood cell count
define sepsis
systemic inflammatory response syndrome and infection
define severe sepsis
sepsis and organ hypoperfusion (no function despite adequate fluid resiscitation and maintaining blood pressure)
severity of sepsis caused by pathogens
gram +ve > gram -ve > fungi
in sepsis, what does the release of pathogens cause
activation of complement pathway
complications of sepsis
organ dysfunction, multi-organ failure, ischaemic tissue (lactic acidosis), acute tubular necrosis
