What is triage?
the sorting of patients into priority levels based on illness/severity. They are the gatekeepers
what is hypo dynamic (COLD) phase of septic shock?
there is inadequate fluid resuscitation/compensation. The body cant compensate anymore it has done everything it can.
What happens in the refractory (IRREVERSIBLE) stage in shock?
thrombi formation -DIC *DIC is when you do not have enough blood/volume but the body is trying to clot but they are immature thus bleeding out -Multi organ dysfunction syndrome -slow/shallow respirations non palpable pulse further cell/tissue damage
what to assess/complications with aortic balloon pump?
thrombus formation assess peripheral circulation warning sign: diminished perfusion
what is the goal for hypovolemic shock?
to decrease O2 demand and metabolic requirements increase perfusion & CO TREAT THE UNDERLYING CAUSE THEN RESTORE FLUID/BLOOD (NS or give packed blood cells) MEDS: Inotropes
what is SOFA (sequential organ failure assessment)?
to describe organ dysfunction or failure evaluates 3 Clinical components... Glasgow Coma Scale when it goes below 13, Systolic BP when it goes below 100 and respiratory state is higher than 22
Level 2 ESI (emergent) examples?
unsafe for pt to remain in waiting room, reassess q 15min ex: needle stick, signs of stroke, ectopic preg, pt on chemo with a fever, open fractures, confusion/lethargy/disoriented
what does dopamine do?
vasoconstrictor (when given in big amounts) vasodilator when given in small amounts *used when other therapies are not effective NEVER GIVEN IV PUSH VS q 15min s/e if infiltrated can cause tissue sloughing/necrosis
what drugs would decrease afterload?
vasodilators to decrease afterload.
Describe what is meant by V/Q ratio ?
ventilation = amount of air traveling into alveoli ready for gas exchange Q= perfusion - amount of blood flow to the alveoli
how do you know if its uncompensated or compensated ?
you look at the pH, if it is normal compensated , if it abnormal its uncompensated
bioterrorism definition?
•Bioterrorism: a deliberate release of pathogenic organisms into a community
