- referencing
- positioning the transducer so that the zero ref point is at the atria of the hear
- furosemide
- diuretic tx of hypotension and edema
- venodialators
- nitroglycerine, nitroprusside, hydralizine
- Frank Starlings Law
- the more a myocardial fiber is stretched in filling, the more it shortens in systole and the greater the force of contraction
- isoproterenol
- cardiac stimulant. bronchodilator
- milrinone
- provides inotropic support. used in heart failure
- digitalis
- cardiac stimulant. strenghthens heart contractions
- PAWP
- 8-12
- dopamine
- tx of shock, hypotension and low cardiac output
- preload
- VOLUME within the ventricle at end of diastole, decreases with diuretics or vasodilation
- succinylcholine
- muscle relaxer
- negative inotropes
- calcium channel blockers, beta blockers, acidosis. Diminished contractility
- stroke volume
- volume ejected within each heart beat
- chronotropes
- change hr by affecting the nerves
- swann ganz
- used to measure PA pressures
- vasopressors
- dopamine, norepinepherine, epinephrine, pheylephrine
- epinepherine
- vasoconstricter. heart stimulant
- dicrotic notch
- change in pressure when aortic valve closes
- phlebostatic axis
- midclavic + 4th intercostal space
- inotropes
- alters force or energy of muscle contractions
- tx of decreased afterload
- vasopressors
- venus oxygen sat
- 60-80
- norepinephrine
- vasopressor. causes vasoconstriction. positive inotrope. increases contractility
- midazolam
- (versed) sedation and pain reliever
- contractility
- the force the lv contracts
- right atrial pressure
- 0-8
- ventricular assist device
- provides long term support for the failing heart
- hydrocortisone
- antianflamatory
- atrial pressure monitoring
- sodium nitroprusside pressors
- cardiac output
- HR X SV amount of blood pumped from the LV in one min
- SVR
- MAP-CVP/CO X 80 normal- 900-1300
- fentanyl
- narcotic analgesic. acts on cns for pain management
- Cardiac index
- co/bsa
- tx of increased afterload
- vasodilators, ace inhibitors, calcium channel blockers
- phenylephrine
- vasoconstrictor
- vasopressin
- antidiuretic. constricts blood cells
- afterload
- PRESSURE determined. Resistance the LV has to pump against. Forces opposing ventricular ejection, decreases with sepic chock. increases with htn
- hypervolemia tx
- diuretics, venodilators, relieve pulm congestion
- nitroglycerin
- vasodialator
