Arteriell blodgas laktat

Lactate is mainly metabolised by the liver and partially by myocytes, though the kidney plays more of a role in metabolism in the presence of hyperlactataemia. Hyperlactataemia Accumulation of lactate is associated with acidosis; lactic acidosis is a high anion gap metabolic acidosis. 1 blodgas tolkning lathund 2 A venous or arterial blood gas is a good way to quickly check potassium and sodium values. This is particularly important in the immediate management of cardiac arrhythmias as it gives an immediate result. Lactate. Lactate is produced as a by-product of anaerobic respiration. 3 varför tar man blodgas 4 Overview What is lactic acidosis? Lactic acidosis is a buildup of lactic acid in your bloodstream. It happens when your body produces too much lactic acid and/or can’t metabolize enough of the lactic acid it produces. Your liver and kidneys normally clear excess lactic acid from your body. 5 [1] A "blood gas analysis" can be performed on blood obtained from anywhere in the circulatory system (artery, vein, or capillary). An arterial blood gas (ABG) tests explicitly blood taken from an artery. ABG analysis assesses a patient's partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2). 6 pyruvate and lactate are in equilibrium. lactic acid has a pK value of about 4 so it is fully dissociated into lactate and H+ at body pH (i.e. it is a ‘strong ion’) Tissues Producing Excess Lactate. at rest, the tissues which normally produce excess lactate are: (i) skin – 25% of production. (ii) red cells – 20%. (iii) brain – 20%. 7 blodgas referensvärden 8 Normalt pH har hög prioritet för homeostasen. 9 Skillnad i pH ligger runt (högre skillnad hos patienter i grav chock, varför. 10 hb(vb)--oxygenmättnad referens 12
