Normal pH for arterial blood. —. 7.35 to 7.45.. Normal pH for venous blood. —. 7.31 to 7.41.. ABGs,. CVADs. Zoya. . Minasyan. , RN, MSN-. Edu. Purpose. Maintain a balance between acids and bases to achieve homeostasis: State of equilibrium. Health problems lead to imbalance. Diabetes mellitus. Patient may or may not notice symptoms .. Life expectancy for stage 1 people is only slightly less than the normal people. . It is around 17.4 years for a male who is 65 year old. . Patients who continue smoking will have shorter life than who does not smoke or who stop smoking. . Acidosis ACIDOSIS REDUCED ACIDOSIS Breath holding after an exhalation causes a decrease to the concentration of oxygen to trigger increased lactic acid, therefore increased H+. At the same time, carbon dioxide also increases leading to an increased concentration of hydrogen ions to further acidify the blood. M. . Gardner. Copyright2/4/2013. ACID /BASE BALANCE. In order to meet homeostasis, the body fluids must maintain a stable chemical balance of hydrogen ions in body fluids.. This is done by regulating their acidity /alkalinity. . MA-PF-AI-SG-0006-1.
