Blood Gas Analyzer

AVL (Roche) Omni 6

This AVL OMNI blood gas analyzer pH, pCO2, pO2, Na, K, Cl, Ca, Co-ox, Hct. There are two broad components to the blood gas panel: respiratory and metabolic. The values reported are as follows: pH--This is a logarithmic expression of hydrogen ion concentration--the acidity or alkalinity of the blood. The normal human arterial pH is 7.4. Any pH below this is acid, and any pH above it is alkaline. There is a narrow range of pH values (7.35 to 7.45) that the human body and its complicated system of enzyme-supported system operates within. pH values below 7.0 and above 7.6 are incompatible with life. HCO3--This value is derived through the blood gas analyzer's manipulation of the Henderson-Hasslebach Equation. An uncompensated decrease in the HCO3 value causes a decline in pH. An increased HCO3 results in alkalinization of the blood. Either condition can be life threatening. Decreased HCO3 is often the result of kidney or other major organ failure or uncontrolled diabetes. Increased HCO3 is more rare and is usually the result of inappropriate administration of certain drugs such as some kinds of diuretics or an excess of NaHCO3. PCO2--This value is measured directly by the CO2 electrode. An increased PCO2 is often the result of acute, chronic or impending respiratory failure, whereas a decreased PCO2 is the result of hyperventilation stimulated by a metabolic acidosis or hysteria and severe anxiety reactions. The normal arterial PCO2 is 40 mmHg. PO2--The partial pressure of oxygen in the blood is measured directly by a polarographic O2 electrode. The normal acceptable range is roughly between 85 and 100. An increased PO2 is usually the result of excessive oxygen administration that needs to be adjusted downwards on such results. A decreased PO2 is often the result of any number of respiratory or cardiopulmonary problems.
