Document Summary
Acid/base balance: process of regulating ph, bicarbonate concentration, and partial pressure of carbon dioxide in body fluid. Blood gases: blood tests that measure acid-base balance of the body. Co2 (35-45): an acid that breaks down when exposed to water and is regulated by the lungs. Hco3 (22-26): a base that is regulated by the kidneys. Po2 (80-100%): a measure of oxygen in the sample (venous bg will have lower normal levels) Mixed venous (mvbg): done in critical care with advanced hemodynamic monitoring pulled from pulmonary artery (pa) catheter (a long catheter through the right atrium, ventricle and pulmonary artery) Body system buffers to maintain ph respiratory renal. Cause: kidneys cannot keep up with acidic excretion demands increased secretion of. Cause: kidneys cannot keep up with bicarbonate excretion demands decreased secretion of. Hypoventilation: bronchitis, emphysema, severe asthma, pneumonia, pulmonary edema. Buffers the blood with bicarbonate, phosphate and proteins. Changes in the depth and rate of breathing.
