Overview of Acid-Base Balance

Acid-base balance is crucial for maintaining homeostasis in the human body. The body regulates pH levels through various mechanisms, including:

• Buffer systems: These include bicarbonate, phosphate, and protein buffers that help neutralize acids and bases.
• Respiratory regulation: The lungs control carbon dioxide (CO2) levels, which directly affect carbonic acid concentration in the blood.
• Renal regulation: The kidneys manage bicarbonate and hydrogen ion excretion, influencing the overall acid-base status.

Clinical Presentation

Patients with a mixed disorder of acid-base balance may exhibit symptoms related to both metabolic and respiratory disturbances. Common clinical features include:

• Respiratory symptoms: Shortness of breath, rapid breathing (hyperventilation), or slow breathing (hypoventilation) depending on the underlying cause.
• Neurological symptoms: Confusion, lethargy, or altered mental status due to changes in cerebral perfusion and oxygenation.
• Cardiovascular symptoms: Arrhythmias or hypotension, which can arise from electrolyte imbalances associated with acid-base disorders.

Causes

Mixed disorders can arise from various conditions, including:

• Chronic obstructive pulmonary disease (COPD): Leading to respiratory acidosis combined with metabolic compensation.
• Diabetic ketoacidosis: Resulting in metabolic acidosis while respiratory compensation may occur.
• Renal failure: Impairing the kidneys' ability to excrete acids, leading to metabolic acidosis, potentially compounded by respiratory issues.

Diagnosis

Diagnosis of a mixed disorder of acid-base balance typically involves:

• Arterial blood gas (ABG) analysis: This test measures pH, partial pressure of carbon dioxide (pCO2), and bicarbonate (HCO3-) levels to identify the type of acid-base disturbance.
• Electrolyte panel: To assess for associated electrolyte imbalances, particularly sodium, potassium, and bicarbonate levels.
• Clinical history and physical examination: To identify underlying conditions contributing to the acid-base imbalance.
