Critical Care
Who is critical care used for?
physiologic instability, at risk for complications, require IV poly pharmacy or advanced technology
What is the progression from SIRS to septic shock
extent and speed that fibers shorten affecting stroke volume
Where are invasive pressure monitoring lines zeroed at?
phlebostatic axis
how many SIRS criteria does it take to be diagnosed
2
A patient's ScVO2 is 40%. What should you do
increase oxygen supply
A pt comes in with a CVP of 10. What nursing diagnosis might you give them?
fluid volume overload
What is the late stage of septic shock and two symptoms
hypodynamic
extreme tachycardia, profound hypotension, SVO2 <60, cool pale skin, abnormal RR, decreased LOC
What is the goal CVP for a patient in septic shock
8-12
understand pathophysiology, pharmacology, technology, understand priority problems
HR>90, RR>20, temperature < 96.8 or >100.4, WBC < 4000 or >12000 or bands >10%
what measure is the average amount of oxygen remaining after all tissues in the body have removed oxygen from hemoglobin
ScVO2
central venous oxygen saturation
Compare a central line and Swan Ganz
central is for giving meds mainly
swan ganz is for microdata
What is the characteristic finding of compensatory shock
HR increase and BP decrease
How much fluid would you give per hour to a patient in septic shock who weighs 40 kg
you give 30 mL/kg/hr so you would give 1200
