JP drain: The original suction drain. The drain itself is inside the body. It is made of Teflon and has multiple drainage holes. The drain is connected to clear plastic tubing which is usually sutured to the skin at the point it leaves the skin. The tubing connects to a bulb reservoir. The bulb, when squeezed empty, applies constant suction to the drain and pulls the fluid out of the body.
Cardiac Enzyme Studies. Cardiac enzyme studies measure the levels of enzymes and proteins that are linked with injury of the heart muscle. These include the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT).
Cardiac enzyme studies measure the levels of the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT) in the blood. Values and units for reporting the results of cardiac enzyme tests vary considerably. The normal values listed here-called a reference range-are just a guide.ardiac enzyme studies measure the levels of the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT) in the blood.
