Multidimensional Care 2 Exam 2 Acid Base Balance is characterized by - Hydrogen atoms too many means more acidic too little means less acidic pH is - how hydrogen concentration is measured lower pH means higher acidity, higher pH means lower acidity What are the main 3 ways the body controls pH? - -Hydrogen atoms ("buffy buffer"/chemical buffer/metabolic buffer) -Respiratory system (carbonic acid) -Renal system (bicarbonate) Gastric Juice pH - 1.0 - 3.0 Urine pH - 5.0-6.0 Arterial blood pH - 7.35-7.45 Venous blood pH - 7.31-4.41 CSF pH - 7.32 Pancreatic fluid pH - 7.8-8.0 When acid base is balanced it is characterized by? - fluid containing equal number of positive charges, ions with negative charges Changes in acid base balance can affect - -shape of hormones and enzymes -distribution of other electrolytes -excitable membranes -effectiveness of hormones and drugs ABG (Arterial Blood Gas) measures - the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery what are 3 parts to an ABG - -pH 7.35-7.45 -Co2 35-45 (this is an acid) (higher the number more acidic) -Hco3 22-26 (bicarb)
