Measurement of Whole Blood PH and Blood Gases
Acid-Base Measurement
PCO2 and PO2 usually in whole blood
Blood Gases
Homeostatic maintenance of acids and bases within the body to achieve a PH
Acid-Base Balance
Arterial Blood PH < 7.35
Acidemia
Arterial Blood PH >7.45
Alkalemia
Equation that defines PH,Bicarbonate, Partial Pressure.
Henderson-Hasselbach Equation
PH = 6.1 + Log(cHCO-/cdCO2
Henderson-Hasselbach Equation
Accumulation of acid that lowers bicarb and decrease PH (Primary bicarb Deficit)
Metabolic Acidosis
Accumulation of base that raises bicarb and increase PH (Primary bicarb Excess)
Metabolic Alkalosis
Accumulation of CO2 that raises PC02 and decrease PH.(Hypoventilation, Emphysema)
Respiratory Acidosis
Excessive elimination of CO2 which lowers PCO2 and increase PH (Hyperventilation)
Respiratory Alkalosis
Commonly measured index of blood hydrogen ions homeostasis
Plasma Bicarbonate (HCO3)
measures partial pressure of oxygen dissolved in blood & how well can oxgen goes into blood
oxygen (PO2)
Measures gaseous CO2 dissolved in blood
Carbon Dioxide (PCO2)
Capacity of oxygen transport. percent of hemoglobin is binding to oxygen
oxygen saturation point SO2
Gas volume that varies inversely with pressure at constant absolute temperature.
