WebMar 14, 2024 · The pH tells you if your patient is acidotic or alkalotic. It is a measurement of the acid content or hydrogen ions [H+] in the blood. Low pH indicates a higher concentration of hydrogen ions (acidosis) while a high pH indicates a lower concentration of hydrogen ions (alkalosis). PCO2: The PaCO2 level is the respiratory component of the ABG.

WebLook at carbon dioxide pressure (PCO2). PCO2 is normally between 35 and 45 mm mercury. Low PCO2 means that the patient is hyperventilating (sometimes to compensate for the blood being acidic), and a low PCO2 means they are under ventilating. Look at bicarbonate levels, which are measured as HCO3. WebSep 12, 2024 · ABG analysis assesses a patient's partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2). PaO2 provides information on the oxygenation status, and PaCO2 offers information on the ventilation …
WebApr 9, 2012 · Arterial blood gas (ABG) analysis consists of three separate measurements—pH, pCO2, and pO2, but depending on the platform may also include calculated values for bicarbonate (HCO 3), base excess (BE), total CO 2 (TCO 2), and blood oxygen saturation (sO 2).Together, these measurements are evaluated to assess … WebNov 5, 2024 · Steps in ABG analysis using the tic-tac-toe method 1.
