blood gases;buffers

pH index of acidity or alkalinity of the blood
blood gases body's mechanism to maintain acid-base balance
acidosis metabolic state that leads to acidema
alkalosis metabolic state that leads to alkaemia
normal pH 7.35-7.45
acid substance that can yield a hydrogen ion or hydronium ion when dissolved in water
base substance that will yield a hydroxyl(OH-) ion when dissolved in water
K value relative strenth of acids and bases and their ability to dissociate in water
buffer combination of a weak acid or base and its salt so that it resists changes in pH.
pCO2 measurement of tension or pressue of carbon dioxide dissolve in blood
pCO2 reference range 35-45mmHg
pO2 meansurement of tension or pressure of oxygen dissolved in blood
pO2 reference range 80-110mmol/L
decreased pO2 is seen in... decreased pulmanary ventilation
acid-base balance maintenance of H+; increased H+, decreased pH; decreased H+, increased pH
bicarbonate-carbonic acid buffer in highest concentration in plasma
Henderson-Hasselbalck equation relates pH, HCO3, pCO2
hemoglobin buffer transports acid from tissues to lungs
phosphate buffer intracellular buffer
albumin/other proteins buffers system that binds H+ because of net negative charge
respiratory acid-base disorder caused by ventilatory dysfunction
metabolic acid-base disorder caused by renal dysfunction
compensation body's attempt to restore acid-base balance
fully compensated body pH has returned to normal range
partially compensated body pH is approaching normal range
metabolic acidosis decrease pH and decreased HCO3-
metabolic alkalosis increase pH and increased HCO3-
respiratory acidosis decrease pH and increased CO2
respiratory alkalosis increase pH and decreased CO2
anion gap eastimate of unmeasured anions and cations
