Radial artery puncture is a medical procedure performed to obtain a sample of arterial blood for gas analysis. Also it is beginning in TRA Trans Radial Access Cardiac coronary angioplasty. A needle is inserted into the radial artery and spontaneously fills with blood. The syringe is either prepacked with a small amount of heparin to prevent coagulation, or must be heparinised, by drawing up a small amount of heparin and squirting it out again. Most commonly, femoral and radial artery puncture is performed to obtain arterial blood sampling for gas analysis. The partial pressures of oxygen (PaO2) and carbon dioxide (PaCO2), and the pH of arterial blood are important in assessing pulmonary function. These data indicate the status of gas exchange between lungs and blood.
How to Interpret Blood Gas Results. An arterial blood gas analysis is used by doctors to measure the partial levels of carbon dioxide, oxygen and the pH in a blood sample. This test can help monitor several conditions that can cause serious health complications.This article will tell you how to interpret blood gas results.nspect the PO2 number in your blood gas test results. This is the amount of oxygen that is dissolved in the blood. The normal PO2 level should be between 80 to 100 mmHg. If they are below limits, there is evidence of hypoxemia, therefore, no compensation is done to restore the pH balance.
