2 ways to change pH?
|
Respiration - blow off more CO2 to inc pH
Metabolic - renal change, by changing bicarbonate |
|
|
Alkalosis vs. acidosis
|
Alkalosis = high pH (low H+)
Acidosis = low pH (high H+) |
|
|
What does an inc in pH with a dec in PaCO2 indicate?
|
This indicates a respiratory problem b/c the respiratory system SHOULD be trying to conserve CO2 and prevent it from being exhaled in order to dec pH
|
|
|
What does an inc in pH with an INC in PaCO2 indicate?
|
A primary metabolic problem
Repsiratory system is trying to retain CO2 to dec pH to its normal level |
|
|
What levels of bicarb and CO2 in relation to pH would tell you primary respiratory vs. metabolic problem?
|
Respiratory: Opposite (pH goes one way and CO2 or bicarb goes the other way)
Metabolic: Both changes are in the same direction |
|
|
Normal levels for:
pH PaCO2 HCO3- |
7.35-7.45
32-48 22-26 |
|
|
What levels of PaO2 are normal, mild hypoxic, moderatley hypoxic, and severely hypoxic?
|
Normal: 80-100 mmHg
Mild: 60-80 mmHg Moderate: 40-60 mmHg Severe: <40 mmHg |
