Flashcards
Respiratory Acidosis
Respiratory Acidosis
Low pH, high PaCO2, and normal HCO3, indicating a respiratory cause of acidosis.
Metabolic Alkalosis
Metabolic Alkalosis
High pH and high HCO3 indicate a metabolic cause of alkalosis, with normal PaCO2 showing no respiratory involvement.
Vomiting and ABG imbalance
Vomiting and ABG imbalance
An acid-base imbalance often caused by loss of stomach acid (HCl), leading to increased bicarbonate levels.

Study Notes
- ABG interpretation involves analyzing pH, PaCO2, and HCO3 values to determine acid-base imbalances
Respiratory Acidosis
- Low pH, high PaCO2, and normal HCO3 indicate respiratory acidosis
- COPD can lead to impaired CO2 excretion, resulting in CO2 retention and respiratory acidosis
Metabolic Alkalosis
- High pH and high HCO3 suggest metabolic alkalosis with normal PaCO2 levels
- Prolonged vomiting can cause metabolic alkalosis due to the loss of stomach acid (HCl), increasing bicarbonate levels
Metabolic Acidosis
- Low pH and low HCO3 indicate metabolic acidosis, with normal PaCO2 to rule out respiratory issues
- DKA produces excess ketones, lowering pH and bicarbonate levels, which can results in metabolic acidosis
Respiratory Alkalosis
- High pH and low PaCO2 indicate respiratory alkalosis with normal HCO3 levels
- Hyperventilation leads to excessive CO2 loss, raising pH and causing respiratory alkalosis
- Anxiety-induced hyperventilation is a common cause of respiratory alkalosis
Compensation
- The lungs compensate for metabolic acidosis by increasing respiration to remove excess CO2 (hyperventilation)
- In fully compensated metabolic acidosis, the pH is within normal limits, HCO3 is low (indicating metabolic acidosis), and PaCO2 is low (indicating respiratory compensation)
