Order when reading ABGs? - Oxygenation status (PaO2, level of FiO2 received, O2 delivery device), acid-base balance (pH), ventilation status (PaCO2-also influences acid-base balance), bicarbonate level What are the clinical indications for drawing an ABG? - Patient has a change in LOC, increasing respiratory difficulty, or low blood pressure (or change in BP on arrival). Why do we need to draw an ABG for a patient with low blood pressure? - Because if the body is acidotic and the pH is ver...
