NUR 211 Perfusion

  • Arterial line info
  • Answer -More accurate -Constant Monitoring -Pressor or Vasodilator med monitoring (some hospital policy) -Need to zero system and level

  • 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

  • ART line comps
  • Answer -Bleeding--> pressure, arm above heart, check to see if pt. needs another placed -Infection -Air embolism -Site issue

  • 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

  • Pre-Load Hemodynamics
  • Answer -Central Venous Pressure 2-8mmHg 1 / 2

Pulmonary artery wedge pressure 4-12mmHG decrease Preload= decreased volume, increased HR, pericarditis

  • 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

  • Pulmonary Artery wedge pressure
  • Answer Reflects left ventricular end diastolic pressure

increased= pulmonary edema, stenosed mitral valve decreased= decreased volume

  • After load
  • Answer Systemic vascular resistance (SVR) 800-1200 dynes/ sec

increased= decreased CO (vasoconstriction) decreased= increased CO (vasodilation)

  • Contractility
  • Answer Comps- Arrythmias, HF, shock CO (SVxHR)

Map--> SBP+ 2(DBP)/ 3

-70-100

  • Bradycardia info
  • Answer <50bmp

s/s--> change in LOC, restless, sweating, decreased BP, Decreased CO
