Summary of "Acid Base Disorders and ABG Interpretation | Introduction"

Main Ideas and Concepts:

Acid-Base Definitions:
- Acidosis: An increase in proton concentration in the body, leading to a decrease in blood pH (acidemia, pH < 7.35).
- Alkalosis: A decrease in proton concentration, resulting in an increase in blood pH (alkalemia, pH > 7.45).
- Normal pH Range: 7.35 to 7.45.
Key Equations:
- pH and Proton Concentration: pH = -log[H⁺]
- Modified Henderson-Hasselbalch Equation: pH = [Bicarb] / [CO₂] (with CO₂ as partial pressure).
Types of Disorders:
- Respiratory Acidosis: Caused by CO₂ retention (high pCO₂), leading to low pH.
- Respiratory Alkalosis: Caused by CO₂ loss (low pCO₂), leading to high pH.
- Metabolic Acidosis: Low bicarb or high proton concentration (low pH).
- Metabolic Alkalosis: High bicarb or low proton concentration (high pH).
Anion Gap:
- Calculation: Anion Gap = Na⁺ - (Cl⁻ + HCO₃⁻).
- Interpretation:
  - Normal AG < 12: Normal Anion Gap Metabolic Acidosis (NAGMA).
  - High AG > 12: High Anion Gap Metabolic Acidosis (AGMA).
Compensation Mechanisms:
- Respiratory Compensation: Quick response (minutes) to metabolic disorders by altering breathing rate to adjust CO₂ levels.
- Renal Compensation: Slower response (hours to days) to respiratory disorders by adjusting bicarbonate and proton excretion.

Methodology for ABG Interpretation:

Check pH: Determine if it is acidemia (< 7.35) or alkalemia (> 7.45).
Analyze pCO₂: Determine if it is elevated (indicating respiratory Acidosis) or decreased (indicating respiratory Alkalosis).
Evaluate Bicarbonate (HCO₃⁻): Assess if it is elevated (indicating metabolic Alkalosis) or decreased (indicating metabolic Acidosis).
Determine Anion Gap: Calculate the anion gap to differentiate between types of metabolic Acidosis.
Delta Ratio (for AGMA): Calculate the delta ratio to identify any concomitant disorders.
Assess Compensation: Determine if compensation is full, partial, or absent based on pH, pCO₂, and HCO₃⁻ levels.
