Understanding Acid-Base Balance: The Foundation of Body Homeostasis
The human body meticulously regulates its internal environment to ensure optimal functioning. One critical aspect of this regulation is maintaining the acid-base balance, primarily reflected in blood pH levels. The normal blood pH ranges from 7.35 to 7.45, slightly alkaline, which is essential for enzymatic activities, metabolic processes, and overall cellular health.
What Is Acid-Base Balance?
Acid-base balance refers to the equilibrium between acids and bases in the body. This balance prevents the blood from becoming too acidic (acidosis) or too alkaline (alkalosis), both of which can have serious health consequences.
Why Is Maintaining Acid-Base Balance Important?
- Ensures proper enzyme function
- Maintains oxygen delivery
- Supports cellular metabolism
- Prevents metabolic disturbances that could lead to organ failure

Key Concepts in Acid-Base Regulation
To understand acid-base balance, it’s essential to grasp some foundational concepts:
pH and Its Significance
- pH is a measure of hydrogen ion concentration
- pH below 7.35 indicates acidosis
- pH above 7.45 indicates alkalosis
Sources of Body Acids and Bases
- Metabolic acids: Lactic acid, ketone bodies, phosphoric acid
- Respiratory acids: Carbon dioxide (CO₂), which combines with water to form carbonic acid
- Metabolic bases: Bicarbonate ions (HCO₃⁻)
Buffer Systems
Buffers are chemical systems that minimize pH changes:
- Bicarbonate buffer system: Most important in blood
- Protein buffers: Hemoglobin and plasma proteins
- Phosphate buffer system: Mainly in intracellular fluid
Respiratory Regulation
- The lungs control CO₂ levels
- Increased respiration removes CO₂, raising pH
- Decreased respiration retains CO₂, lowering pH
Renal Regulation
- Kidneys excrete hydrogen ions (H⁺) and reabsorb bicarbonate (HCO₃⁻)
- This process is slower but provides long-term pH regulation

Types of Acid-Base Imbalances
Understanding the different types of disturbances helps in diagnosis and management:
Respiratory Acidosis
- Caused by hypoventilation
- Elevated CO₂ levels
- pH decreases (becomes more acidic)
- Common causes: COPD, respiratory depression
Respiratory Alkalosis
- Caused by hyperventilation
- Reduced CO₂ levels
- pH increases (becomes more alkaline)
- Common causes: Anxiety, fever, pain
Metabolic Acidosis
- Due to excess acid or loss of bicarbonate
- pH decreases
- Causes: Diabetic ketoacidosis, renal failure, diarrhea
Metabolic Alkalosis
- Due to excessive loss of acid or excess bicarbonate
- pH increases
- Causes: Vomiting, diuretic use, excessive antacid intake

How to Interpret Acid-Base Disorders: Step-by-Step Approach
Interpreting blood gases and understanding acid-base disturbances is fundamental for clinicians. Here's a simplified step-by-step guide:
- Check the pH: Is it normal, acidic, or alkaline?
- Assess the primary disturbance: Based on pH, determine if it’s acidosis or alkalosis.
- Evaluate the CO₂ and HCO₃⁻ levels: Helps identify whether respiratory or metabolic component is involved.
- Determine compensation: Is the body compensating for the primary disturbance? Look for expected changes.
- Identify mixed disorders: When both respiratory and metabolic disturbances occur simultaneously.
