resp and renal reg
| Question | Answer |
|---|---|
| Lungs control _ | CO2 |
| Kidneys control _ | HCO3 |
| hyperventilation does what with CO2 | eliminates CO2 |
| hypoventilation does what with CO2 | retains CO2 |
| what is the time frame for resp regulation to take effect | seconds to minutes |
| Home is resp regulation measured and what is the normal range | PaCO2 ; 35-45 mm Hg |
| what are the kidneys mechanism of control | excretion or retention of h+ or HCO3 |
| Renal reuglation takes _ to change pH | hours to days |
| what is the normal serum range of HCO3 | 22-26 mEq/L |
| Cellular level is | changes brought about by systemic alterations |
| increase in bl carbonic acid/decrease in bicarbonate describes what condition | acidosis |
| increase in bicarbonate/ decrease in carbonic acid describes what condition | alkalosis |
| Resp acidosis is brought on by these conditions; | COPD, emphysema, pneumonia, inadequate mechanical ventilation; hypoventilation, pulmonary edema |
| what are symptoms of resp acidosis | labored breathing, cyanosis, CNS depression, drowsiness, stupor, disorientation |
| what causes metabolic acidosis | decrease in HCO3 and subsequent decreased pH |
| decrease in dissovled CO2 in the blood whichin turn increases bl pH | resp alkalosis |
| what factors can influence resp alkalosis | fever; toxic effects of drugs ASA |
| symptoms of resp alkalosis is | lightheaded, agitation, nervousness, tingling |
| vomiting, gastric lavage, use of diuretics, admin of alkali-antacids can cause | metabolic alkalosis |
| symptoms of metabolic alkalosis is | decreased rate and depth of breathing, irritability, weakness, decreased intestinal motility |
| what are the tx for | fl theraphy to replace Cl-, k+, and other electrolytes |
