Base excess in the other. A secondary (compensatory) process can be readily identified because it "opposes" the observed deviation in blood pH. For example, inadequate ventilation, a respiratory problem, causes a buildup of CO, hence respiratory acidosis; the kidneys then attempt to compensate for the low pH by raising blood bicarbonate. The kidneys only partially compensate, so the patient may still have a low blood pH, i.e. acidosis. In summary, the kidneys partially compensate for respiratory acidosis by raising blood bicarbonate. A high base excess, thus metabolic alkalosis, usually involves an excess of bicarbonate. It can be caused by A base deficit
Blood lead level glass of water containing lead and absorb 50% of it. An adult might only retain 10% of the lead in that water. And once the lead is in the child's body, it reaches the brain through the not fully developed blood brain barrier. The body removes lead from blood and stores it in bone, but in children it subsequently leaves the bone more readily compared to adults. "Lead that has accumulated in a woman's bones is removed from her bones and passes freely from mother to child; maternal and fetal blood lead levels are virtually identical. Once in the fetal
