Blood gases provide more accurate information about acid-base and oxygen status than the chemistry Blood gas/lytes plus panel, pO2, pCO2, pH, bicarb., Tot.

chronic respiratory acidosis: Change in pH = 0.003 X (40 - PaCO2) determine if another primary acid/base disturbance is occurring calculate AG; if HCO3 < 24 + (pCO2-40)/10 x 3(+/-1) then there is a superimposed primary metabolic acidosis pCO2 (partial pressure of carbon dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood. Indirectly, the pCO2 reflects the exchange of this gas through the lungs to the outside air. Two factors each have a significant impact on the pCO2. The first is … Arterial vs. Venous blood.

The ABG test also evaluates the partial pressure of oxygen (PaO2), bicarbonate ( HCO3), and the pH level of blood.

pCO2 gap is a surrogate for cardiac output; pCO2 gap = PcvCO2 - PaCO2; pCO2 gap >6 mmHg suggests a persistent shock state that may be amenable to fluid resuscitation +/- intrope support; a “ScvO2-cvaCO2gap-guided protocol” has been proposed to guide the management of septic shock

SUMMARY.
English writing prompts

Respiratorisk acidos. (akut). HCO3.

Under normal circumstances, the PETCO 2 (the CO 2 recorded at the end of the breath which represents PCO 2 from alveoli which empty last) is lower than PaCO 2 (average of all alveoli) by 2-5 mmHg, in adults.1-8 The (a-ET)PCO 2 gradient is due to the V/Q mismatch in the lungs (alveolar dead space) as a result of temporal, spatial, and alveolar mixing defects. pCO2 (partial pressure of carbon dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood.
