Blood gas analysis (BGA) involves measurement of three parameters: the amount of free (unbound) oxygen (O 2) and carbon dioxide (CO 2) dissolved in blood, and the pH (acidity/alkalinity) of blood.. The partial pressure (p) exerted by the two gases is what is actually measured so the three …

WebBlood gases provide information concerning the oxygenation, ventilatory, and acid-base status of the patient. Blood gas results are usually given as pH, Po 2, Pco 2, [HCO 3 –], base excess or deficit (base difference), and O 2 saturation. This test gives information on acid–base homeostasis (pH, Pco 2, [HCO 3 –], and base difference) and on blood … WebIn direct method (VBG), the electrolytes are measured on an undiluted sample with a turn over time of between 2–3 minutes, whereas in indirect method (LBM), the plasma sample is diluted then analysed, with the process time being at least 30 minutes, as such to be able to reliably utilise the VBG results in assessment and management of a …

WebThe average saturation of blood from all organs (mixed venous blood (SvO₂)) is therefore normally around 75 % (1, 2). SvO₂ is measured in samples taken from the distal port of a catheter in the pulmonary artery, but the use of these is generally in decline (3).
