Question | Answer |
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 |
