Let's see how much you guys have been paying attention to my blog. What follows are two cord blood gases and a few questions:
- pH 7.36
- CO2 42.8
- PO2 33.7
- SO2 80.5
- FO2Hb 75.7
- HCO3 23.8
- BE -1.1
- pH 7.27
- CO2 58.8
- PO2 12.3
- SO2 19.5
- FO2Hb 18.8
- HCO3 26.3
- BE -1.3
1. Which one of the above is arterial and which one is venous?
2. Are these results normal or critical?
3. What did you use for the basis to answer question #2? Or, how do you determine if a cord blood gas is critical?
4. If you can only draw venous or arterial from the cord, which would you rather have: venous or arterial?
5. Do cord blood gases have clinical significance?
I will provide the answers at 1900 tonight, or you can find them in this post. Share your answers in the comments below, if you're confident. And so you know, I asked these same questions to all my coworkers, and not one of them got the right answers.
