| Question | Answer |
|---|---|
| What is the normal pH range? | 7.35-7.45 |
| What determines the ventilation status of a patient? | PaCO2 |
| what is the normal range for HCO3? | 22-26 |
| what is the rule of thumb? | the PaCO2 should be about 5 times the FIO2 |
| When does the pH become acidosis or alkalosis | anything below 7.35 is acid and anything above 7.45 is alkalosis |
| true of false does oxygenation decrease with age? | true |
| what is the normal PaCO2? | 35-45 |
| the normal range for PaO2? | 80-100 |
| what are the different ranges for hypoxemia? | >60mm hg is mild hypoxemia 40-59mm hg is moderate hypoxemia <40mm hg is serve hypoxemia |
| uncompensated | C02 and HCO3 is NOT going in the same directions |
| compensated | pH is normal and CO2 and HCO3 are going in the same direction |
| partially compenstated | pH is out of range and CO2 AND HCO3 are going to the same direction. |
| what is the normal number for COHB? | <3.0% |
| what does the COHB indicate? | if the patient was exposed to carbon monoxide or a house fire. |
| what is the normal number for MetHb? | <2.0% |
| what does the MetHb indicate? | if the patient is a smoker |
| what is a metabolic issue? | HCO3 and BE |
| what is a respiratory issue? | CO2 |
| what is the oxygenation status? | PaO2 |
| how to fix oxygenation? | increase FI02 |
| what are the last names? | acidosis, alkalosis, and normal |
| what are the first names? | compensated,uncompensated, partially compensated |
| what are the middle names? | respiratory, combined, metabolic |
