Prophecy General ICU RN A V1, V2 &V3 Prophecy General ICU RN A V1 What is cardiac tamponade? Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. Effects of Hyper/Hypokalemia and calcemia on EKG Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? 90-120/60-80 Normal HR? 60-100 bpm Normal CO? 4-8 L/min Normal SVR? 800-1,200 dynes/seconds Normal PVR? 37-250 dynes/sec/cm5 Normal SVo2? 60-80% Normal PAP? Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal CVP?

RV failure - treatment after RV MI Right sided measurements are more related to fluid balance and build up of fluid in the peripheral side. RV failure leads to insufficient LV preload. The result is low SV and CO. Treatment involves fluid loading with hypertonic fluids (3% saline, mannitol, 20% albumin) IABP optimal timing Inflation during diastole (AV closure) and deflation during systole (QRS) IABP functions Decrease afterload and increase coronary artery perfusion IABP waveforms Unassisted Systolic Unassisted End Systolic Assisted Diastolic Assisted End Diastolic Unassisted End Diastolic MI Leads Septal V1, V2 Anterior V3, V4 Lateral I, aVL, V5, V6 Inferior II, III, aVF Endocarditis inflammation of the inner lining of the heart Where do most thrombi occur?
