CICU Labs

4. Elevated levels of this marker can indicate hemolysis, commonly monitored in patients with ventricular assist devices
7. Bedside test offering rapid insight into oxygenation and ventilation during clinical decline
9. Test that measures the extrinsic pathway of coagulation and is used to assess clotting function
13. Broad biomarker elevated with presence of infection
15. Hormone that helps the heart and blood vessels respond to stress/Marker released by the heart in response to volume overload, aiding in heart failure diagnosis
17. To make sure the acid is being reduced due to increased risk of gastritis, GI bleed on VADs (daily lab)
18. Must have dual verifier before tubing this lab
19. Biomarker that rises in response to bacterial infection, helping to distinguish between bacterial and viral causes

1. We ideally like this value greater than >30%
2. “Basic” green top we get (mostly) everyday
3. Checked after giving first dose of propranolol
5. This lab is done on arrival from OR/direct admit, involves obtaining samples from 3 different parts of the body
6. Protein complex involved in muscle contraction; often measured to assess heart damage
8. Key indicator of oxygen delivery vs. demand; this value will be lower in single ventricle patients
10. Blood lipids elevated with prolonged propofol infusion
11. These two blue-top labs have to be hand delivered to lab
12. Metabolic byproduct elevated in tissue hypoxia or sepsis
14. Electrolyte checked when patient has ST elevation/arrhythmias,often monitored in patients on diuretics
16. Crucial electrolyte in myocardial contractility and rhythm, often checked in critically ill patients with arrhythmias
20. Biomarker for acute kidney injury, more sensitive than BUN and creatinine, especially in cardiac patients with poor renal perfusion
