NUR 211 Perfusion1. Arterial line info
Answer
-More accurate
-Constant Monitoring
-Pressor or Vasodilator med monitoring (some hospital policy)
-Need to zero system and level
2. ART line zeroing
Answer
NEED to look at pressure bag--> blood and fluid meeting each other gives you BP reading
-3ml/hr
-level and zero @ phlebostatic axis--> NEEDs to be accurate for reading so can tx BP
Wave form--> dicrotic notch= Aortic valve closes Allen test to test collateral perfusion
3. ART line comps
Answer
-Bleeding--> pressure, arm above heart, check to see if pt. needs another placed
-Infection
-Air embolism
-Site issue
4. pulmonary artery Catheter
Answer
Ind --> unexplained or unknown volume status in shock, severe cardio shock, Pulmonary HTN
-Balloon inflates for short time--> reading behind balloon
5. Pre-Load Hemodynamics
Answer
-Central Venous Pressure 2-8mmHg
, Pulmonary artery wedge pressure 4-12mmHG
decrease Preload= decreased volume, increased HR, pericarditis
6. CVP (central venous pressure)
Answer
Measurement of end diastolic pressure in right ventricle
Increase= too much volume, peep, right ventricular failure
Decreased= decreased blood,hemorrhage, 3rd spacing, vasodilation TX
Increased- diuretics, decreased peep
Decreased- pressor, decreased vasodilator, increase volume
7. Pulmonary Artery wedge pressure
Answer
Reflects left ventricular end diastolic pressure
increased= pulmonary edema, stenosed mitral valve decreased= decreased volume
8. After load
Answer
Systemic vascular resistance (SVR) 800-1200 dynes/ sec
increased= decreased CO (vasoconstriction) decreased= increased CO (vasodilation)
9. Contractility
Answer
Comps- Arrythmias, HF, shock CO (SVxHR)
Map--> SBP+ 2(DBP)/ 3
-70-100
10. Bradycardia info
Answer
<50bmp
s/s--> change in LOC, restless, sweating, decreased BP, Decreased CO
