Web8 feb. 2024 · Maintaining the pH of blood is essential for normal bodily function; however, several clinical scenarios can result in disruption of the body’s acid-base balance. Monitoring of acid-base balance is done by testing patients’ arterial blood gases (ABGs). The results of ABG testing will often influence the treatment that patients receive. … WebO2 solubility in blood is very low, hence dissolved O2 content is very low at normal PO2 = 100 mm Hg O2 solubility = 0.003 mL/dL per mm Hg (a constant independent of prevailing PO2) O2 content = 0.3 mL O2/dL (a variable dependent upon prevailing PO2) Oxygen Carriage by Hemoglobin
