Blood Gas evaluation study guide questions
| Question | Answer |
|---|---|
| Normal value for pH | 7.35-7.45 |
| Normal value for PaCO2 | 35-45 mmHg |
| Normal value for PaO2 | 80-100 mmHg |
| Normal value for HCO3 | 22-26 |
| Normal value for BE | +-2 |
| Normal value for SaO2 | 95-97% can be 100% |
| pH acidosis | less than 7.35 |
| pH alkalosis (base) | more than 7.45 |
| CO2 acidosis | more than 45 |
| CO2 alkalosis | less than 35 |
| HCO3 acidosis | less than 22 |
| HCO3 alkalosis | more than 26 |
| What is happening with respiratory acidosis | increased CO2 in the lungs |
| What is happening with respiratory alkalosis | decreased CO2 in the lungs |
| What happens with metabolic acidosis | decreased HCO3 in kidneys |
| What happens with metabolic alkalosis | increased HCO3 in kidneys |
| What hapens in combined acidosis | increased CO2 in the lungs and decrease HCO3 in kidneys |
| What happens in combined alkalosis | decreased CO2 in the lungs and increase HCO3 in kidneys |
| Uncompensated | either the HCO3 or CO2 must be w/in normal limits or pH is not normal |
| compensated | pH is w/in normal limits or Both PCO2 and HCO3 are outside their normal ranges |
| partially compensated | pH is not normal and/or both PCO2 and HCO3 are outside their normal ranges |
| combined | Three parameters are all either acid or all alkaline |
| Normal oxygenation | 80-100 |
| mild oxygenation (hypoxemia) | 60-79 |
| moderate oxygenation (hypoxemia) | 40-59 |
| severe oxygenation (hypoxemia) | less than 40 |
| hyperoxia | more than 100 |
| What do if you have resp acidosis | increase ventilation (rate or depth of respiration) |
| What to do if you have resp alkalosis | decrease ventilation (rate or depth of respiration) |
| What to do if you have metabolic acidosis | stop diarrhea, treat kidney failure |
| What to do if you have metabolic alkalosis | DC NG tube, stop vomiting |
