Could someone verify if I am construal blood gas volumes correctly. Here are my problems and answers.?
pH 7.53, PaC02 33, HC03 25=metabolic alkalosis
pH 7.40, PaC02 26, HC03 16=metabolic acidosis
pH 7.31, PaC02 58, HC03 25=respiratory acidosis
pH 7.64, PaC02 48, HC03 47=metabolic alkalosis
Answers: It's not blood gas volumes you are trying to understand, but blood gas values. I checked your answers, and your conclusions seem to be sound. Generally, the sophisticated the CO2 levels, the greater the accidental the acidosis is respiratory in disposition. If your bicarbonate gets out of whack, it's usually metabolic contained by origin. However, the middle values pH 7.40, CO2 26 and HCO3 16 should be compensated respiratory alkalosis, as the pH is common, but the CO2 is low. Bicarb is low in that skin to compensate.
Okay, here's how I do it: First I look at the pH. If it's under 7.35, I know it's "something acidosis". If it's above 7.45, I know it's "something alkalosis".
Then I look to see if the PaCO2 is out of common range (normal mortal b/w 35-45). If it's out of whack, I know it's "Respiratory something".
If the PaCO2 is fine but the HCO3 is less than 22 or highly developed than 30, I know it's "metabolic something."
Then I add those things together to go and get my answer! If both PaCO2 and HCO3 are out of range, next you have own to add "beside compensation" to your answers.
You have completed 5 problems. They are adjectives correct except for two-- I would look over #2 and #3 again. Let me just review the norm and establish that pH: 7.35-7.45; PaCO2: 35-45; HCO3: 22-26.
"pH 7.53, PaC02 33, HC03 25=metabolic alkalosis"
---This one is alkalosis, but it is respiratory alkalosis. Bicarbonate is normal, but CO2 is lower than average. When pH and PaCO2 go surrounded by opposite directions, it is respiratory within origin.
"pH 7.40, PaC02 26, HC03 16=metabolic acidosis"
---This one is completely compensated. The pH is majority but both PaCO2 and HCO3 are still abnormal. The compensation usually cause a leaning pH (meaning the pH lean toward the initial disorder) as clue, but this one is right in the middle of the inventory. The body will never overcompensate, so the conclusion on this one is that it is a "mixed disorder", meaning that it suitcase has both acidotic and alkalotic process.
I hope this help.
