ICU Prophecy - CV

ICU Prophecy - CV Asymptomatic bradycardia treatments - ANS What is cardiac tamponade? - ANS Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. Effects of Hyper/Hypokalemia and calcemia on EKG - ANS Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? - ANS 90-120/60-80 Normal HR? - ANS 60-100 bpm Normal CO? - ANS 4-8 L/min Normal SVR? - ANS 800-1,200 dynes/seconds Normal PVR? - ANS 37-250 dynes/sec/cm5 Normal SVo2? - ANS 60-80% Normal PAP? - ANS Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal CVP? - ANS 2-6 mmHg V-fib in relation to CO - ANS V-fib produces an ineffective stroke, decreasing SV and CO. RV failure - treatment after RV MI - ANS 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)
