Blood Gas Analyzer Principle

Blood gas analyzer principle. The blood can also be drawn from an arterial catheter. The remaining 1 2 of the oxygen transported in blood is dissolved in the blood plasma this is the portion reported as partial pressure of oxygen po 2 2 3. The operating principles behind sensor technology have largely remained unchanged even though the size of analyzers and thus of sensors has decreased remarkably. In arterial blood 98 99 of oxygen is transported in erythrocytes bound to hemoglobin.

Blood gas analyzer techniuqe used to measure the concentration of bcarbonate partial pressure of o2 co2 in the lungs and dtermine the o2 saturation to evaluate. Integral parts of po electrode ie platinum electrode silver silver chloride reference electrode their working reaction at electrode is presented here. Blood gas and ph analysis and related measurements. An arterial blood gas abg test measures the amounts of arterial gases such as oxygen and carbon dioxide an abg test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle but sometimes the femoral artery in the groin or another site is used.

For medium to high volume settings our abl800 flex blood gas analyzer offers a high throughput and reliable automated sample handling with drop n go capability which means there s no need to wait at the analyzer for results. An abg test measures the blood gas tension. Figures include schema of the three electrodes a pulse oximeter probe an acid base compensation diagram and photographs of the first three function blood gas analyzer a combined p o 2 p co 2 transcutaneous electrode in use on a child and a pulse oximeter probe on. Blood gases are in fact the only direct measure of the adequacy of ventilation.

Blood gas analyzer principle. Polari graphic method for po measurement using po electrode is explained. Interpretation of blood gases and acid base balance is briefly discussed. Principle important components of blood gas analyzer are presented in lucid language.

Radiometer offers you a wide selection of blood gas analyzers with features and functionality that match your facility s needs. Today s blood gas sensors are the result of many years of gradual improvements and optimizations. Principles of operation blood gas ph analyzers use electrodes to determine ph partial pressure of carbon dioxide and partial pressure of oxygen in the blood. Transforming care delivery by elevating your blood gas solution allowing you to focus on your patients.
