2024 CVICU TEST STUDY GUIDE GRADED A+ SVO2 Mixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. This refects the amount of oxygen "left over" after the tissues remove what they need. SVO2 Normal >60% Low SVO2 Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infection High SVO2 increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesth...

Pulmonary artery pressure (PAP) - Systolic 15-30 mmHg Diastolic 5-15 mmHg Stroke volume (SV) - 50-100 ml/beat Symptoms of Systolic heart failure - Decreased stroke volume, decreased ejection fraction, S3 and enlarged heart Physical signs of DIC - Hypotension, Petechia, Purpura, Bruising, Bleeding in oral, GI/GU, or pulmonary Symptoms of Left heart failure - Orthopnea, dyspnea, crackles, Low PaO2, SaO2 & SpO2, S3 & S4, Increased PAOP & PA pressures Mean arterial pressure (MAP) - 70-105 m...
