A 48 year-old female is admitted to the ED with diaphoresis, jugular venous distension, and 3+ pitting edema in the ankles. These findings are consistent with - correct answer heart failure A patient is admitted to the ED following a motor vehicle accident. On physical exam, the respiratory therapist discovers that breath sounds are absent in the left chest with a hyperresonant percussion note. The trachea is shifted to the right. The patient's heart rate is 45/min, respiratory rate is 30/...

Order when reading ABGs? - Oxygenation status (PaO2, level of FiO2 received, O2 delivery device), acid-base balance (pH), ventilation status (PaCO2-also influences acid-base balance), bicarbonate level What are the clinical indications for drawing an ABG? - Patient has a change in LOC, increasing respiratory difficulty, or low blood pressure (or change in BP on arrival). Why do we need to draw an ABG for a patient with low blood pressure? - Because if the body is acidotic and the pH is ver...

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...
