| Question | Answer |
|---|---|
| PH Lab value: | 7.35-7.45 |
| HCO3 General information | Amount of bicarb dissolved in blood primarily influenced by metabolic changes |
| HCO3 Lab value: | 22-26 (Low end acidotic, High end alkalotic) |
| PACO2 Lab value: | 34-35 Low end alkalinity, high end acidity |
| How does the body compensate for Respiratory Acidosis? | Kidneys retain bicarb and release H+ to increase ph |
| How does the body compensate for Respiratory Alkalosis? | Kidneys retain H+ and excretee bicarb to decrease pH |
| How does the body compensate for Metabolic Alkalosis? | Respirations decrease which increases in CO2 and carbonic acid, which increases bicarb and pH |
| What actions in the body causes Metabolic Acidosis? | Decreased bicarb (from diarrhea, DKA or renal failure) causes increased carbonic acid and decreased pH |
| What actions in the body causes Metabolic Alkalosis? | Increased bicarb (from prolonged vomiting, dialectics, antacids) causes a decrease in carbonic acid and increased pH |
| What is the problem if the CO2 drops below 35? | Respiratory Alkalosis |
| What is the problem if the CO2 rises above 45? | Respiratory Acidosis |
