 pH indicates the number of Hydrogen Ions H+ Normal range for pH 7.35 - 7.45 condition in which acid accumulates in the body Acidosis condition in which base substances accumulate in the body Alkalosis pH Up Alkalosis pH down acidosis 1st step to blood gas interpretation look at pH and determin a/b status 2nd step to blood gas interpretation look at respiratory component to see if the imbalance is due to a respiratory reason 3rd step to blood gas interpretation look at metabolic component to determine if imbalance is due to a metabolic reason What is the normal ratio of base to acid? 20:1 Measures the pressure exerted by CO2 dissolved in the blood PCO2 Respiratory component of blood gases PCO2 PCO2 normal values 35 - 45 mmHg Measures the amount of bicarbonate (base) in blood HCO3 Metabolic component of blood gases HCO3 HCO3 normal values 22 - 26 mEq/L measures the patial pressure of O2 dissolved in blood PO2 indicates the ability of the lungs to allow Oxygen to diffuse into bloodstream PO2 Normal range of PO2 80 - 100 mm Hg Percentage of hemoglobin that is saturated w/ oxygen O2 saturation each molecule of hemoglobin can carry how many molecules of oxygen? 4 Normal value for O2 saturation 95 - 100% measures all the bases inteh blood that are available to help buffer Base Excess (BE) Normal value for base excess -2 to +2 provides a more complete picture of body's ability to buffer Base Excess (BE) 3 causes of respiratory acidosis 1. primary lung function problem 2. changes in the lungs from secondary problems 3. condition that obstructs airway or depresses respiratory effort what condition is caused by increases in CO2 in blood causing an increase in H+ respiratory acidosis in what condition does K+ move out of cells so H+ move into cells creating high serum potassium levels Acidosis in what condition do cells release H+ into the blood and K+ move into cells from blood serum causing low K+ levels Alkalosis in what condition does CO2 increase and HCO3 decrease? Acidosis in what condition does CO2 decrease and HCO3 increase? Alkalosis if pH is abnormal and both CO2 and HCO3 are abnormal, what is the compensation level? partially compensated if pH is abnormal and either, but not both, CO2 or HCO3 is abnormal, what is the compensation level? Uncompensated if pH is normal and both CO2 and HCO3 is abnormal, what is compensation level? Compensated what are some possible reasons for metabolic acidosis? (handout from class) Diabetic ketoacidosis, shock, kidney failure what are some reasons for respiratory acidosis (handout from class) sedation, shock, severe pneumonia what are some reasons for metabolic alkalosis vomiting, fever, tachypnea what are some reasons for respiratory alkalosis? hyper ventilation, pain, anxiety If a person has pH 7.24 PCO2 31 HCO3 18 what acid/base condition is it and what may have caused it? part. compensated metabolic acidosis; Diabetic ketoacidosis pH: 7.16 CO2: 64 HCO3: 28 partially compensated resp. acidosis; asthma pH: 7.52 CO2: 28 PCO3: 20 partially compensated respiratory alkalosis; hyperventilation or pain pH: 7.48 CO2: 40 PCO3: 32 partially compensated metabolic alkalosis; vomiting pH: 7.37 CO2:56 HCO3: 34 metabolic alkalosis, compensated; sedation
