Acid/Base Disorders: Therapy III: Exam I

Terms in this set (35)

12-20 breaths per minute
What is the normal respiratory rate?
Add 0.05 to the pH
Subtract 5 from the PCO2
You are given a VBG instead of a BMP. How do you correct the pH and PCO2 values?
respiratory alkalosis due to a decrease in PCO2 (you are breathing it out very quickly)
Hyperventilation can cause ____________________. How?
respiratory acidosis due to an increase in PCO2 (you are holding it in too long)
Hypoventilation can cause ________________. How?
acidosis
< 7.4 is _____________.
alkalosis
>7.4 is ____________.
respiratory
A patient has acidosis. You notice their PCO2 is elevated. Classify their acidosis.
metabolic
A patient has acidosis. Their HCO3- is below baseline. Classify their acidosis.
pH/PaCO2/PaO2/HCO3-/BE/SaO2
Complete the skeleton for lab interpretation:
x/x/x/x/BE/x
The body will compensate for increased PCO2 by increasing HCO3- to balance. If PCO2 is below baseline, you would expect HCO3- to drop as well.
You should expect pCO2 and HCO3- levels to be inversely related. Why?
40
PaCO2 interpretation value
80
PaO2 interpretation value
24
HCO3- interpretation value
90%
SaO2 interpretation value
respiratory acidosis
A patient has a pH of 6.9 and a PaCO2 of 52. Classify.
