Arterial Blood Gas (ABG) ABG: technique used to identify the specific acid-base disturbance . it is usually based on arterial sampling. Normal ranges of ABG: 1.PH: 7.35_7.45 2.paCO2: 35_45 3.paO2: 80_100 4.Oxygen saturation : 95% _100% 5.HCO3: 22_26 Definitions: Acidemia: is the decrease in PH to less than 7.35 Alkalemia: is the increase in PH to more than 7.45 Acidosis : condition in which there is an increase in hydrogen concentration in blood Alkalosis : condition in which there is decrease in hydrogen concentration in blood compensation Respiratory compensation: it is condition occurs when the patient has acidosis or alkalosis from metabolic or renal disorder . the respiratory system respond by increasing or decreasing respiratory rate. Renal compensation : it is condition occurs when the patient has acidosis or alkalosis from respiratory disorder . the kidney respond by altering the hydrogen ion and bicarbonate to return PH back toward normal. يتبع .........
