ICU Prophecy – CV || All Correct.

What is cardiac tamponade? correct answers Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. Effects of Hyper/Hypokalemia and calcemia on EKG correct answers Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? correct answers 90-120/60-80 Normal HR? correct answers 60-100 bpm Normal CO? correct answers 4-8 L/min Normal SVR? correct answers 800-1,200 dynes/seconds Normal PVR? correct answers 37-250 dynes/sec/cm5 Normal SVo2? correct answers 60-80% Normal PAP? correct answers Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal CVP? correct answers 2-6 mmHg V-fib in relation to CO correct answers V-fib produces an ineffective stroke, decreasing SV and CO. RV failure - treatment after RV MI correct answers 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 correct answers Inflation during diastole (AV closure) and deflation during systole (QRS) IABP functions correct answers Decrease afterload and increase coronary artery perfusion IABP waveforms correct answers Unassisted Systolic Unassisted End Systolic Assisted Diastolic Assisted End Diastolic Unassisted End Diastolic MI Leads correct answers Septal V1, V2 Anterior V3, V4 Lateral I, aVL, V5, V6
