If this cannot be done, the sample should be packed in ice to slow the degradation of the gaseous components. It is also prudent to perform the blood analysis within 15 minutes of draw time. As blood gas analyzers process whole blood, the technologist must always maintain complete homogeneity of the sample by ensuring complete mixing and avoiding settling of the red blood cells from the liquid plasma. The use of heparin salts in the collection vial or syringe is necessary to prevent clotting and utmost care must be made to avoid introducing air into the sample. The ideal specimen is drawn from the radial or femoral artery, or from a central line accessing arterial blood. Proper collection and transport of the blood specimen is paramount for obtaining accurate results. If a BGA is producing inaccurate results, it could be a problem with the sample, not the device itself. A K + reading of less than 2.5 or greater than 7.0mmol/L in blood plasma is lethal in the human body. A good example is potassium, which is measured at 3,000–4,000 mmol/L in the body but has a normal range of 3.4–4.5 mmol/L in plasma.
It is important to accurately measure the small changes in the electrolytes present in the plasma component of the blood. The percentages of these electrolytes in the blood plasma are low compared to the levels incorporated in the intercellular, tissue, and skeletal body structures. The level of electrolytes in the blood plasma, including the cations sodium (Na +), potassium (K +), and calcium (Ca ++), and the anion chloride (Cl −−). These measurements reflect the build up or breakdown of chemical components in the body, indicating pulmonary status or disease condition. Common blood gas analyzers will measure glucose, lactate, and bilirubin. This relationship is due in part to the complex dynamic buffering of the CO 2 gas being dissolved and converted to carbonic acid in the blood. It is important to note that the pH measurement can be affected by the actions of pCO 2 and the body's adjustment of the pH level can greatly affect the changes in pCO 2. Put simply, the higher the pH reading, the more alkaline the blood. The second component is pH, which is defined as the negative logarithm of the hydrogen ion activity present in the blood. i-STAT Controls for blood gases, electrolytes, and chemistries. The gas component is the partial pressure of carbon dioxide (pCO 2) present in whole blood. The blood's acid-base status, which measures two primary components. A pO 2 determination indicates oxygen uptake in the body.
