Arterial Blood Gases (ABG's) Questions and Answers Already Passed What is an ABG? It measures the partial pressures of O2, CO2, pH, and HCO3 in arterial blood. Who usually collects this bloodwork? From where? Respiratory therapists commonly collect arterial blood from the radial, brachial, and femoral arteries for this profile. What is acidosis? It occurs when arterial blood has an excess of H+ ions, resulting in a pH below 7.35. What are the acids? They include H+...
