What are the causes, effects, compensatory mechanisms, and diagnostic findings of acidosis and alkalosis in the respiratory and metabolic systems?
Understand the Problem
The question appears to be related to the understanding of acid-base imbalances in the human body, specifically focusing on the causes, effects, compensatory mechanisms, and diagnostic findings associated with acidosis and alkalosis in both the respiratory and metabolic systems.
Answer
Acidosis and alkalosis involve causes, effects, compensatory mechanisms, and diagnostic findings: - Respiratory Acidosis: Slow breathing, increased PaCO₂, kidney compensation. - Respiratory Alkalosis: Hyperventilation, decreased PaCO₂, kidney compensation. - Metabolic Acidosis: Diarrhea, decreased bicarbonate, respiratory compensation. - Metabolic Alkalosis: Vomiting, increased bicarbonate, respiratory compensation.
The key causes, effects, compensatory mechanisms, and diagnostic findings for acidosis and alkalosis in respiratory and metabolic systems are:
Respiratory Acidosis:
- Causes: Slow, shallow respirations, respiratory congestion.
- Effects: Increased PaCO₂.
- Compensatory Mechanism: Kidneys excrete more hydrogen and reabsorb more bicarbonate.
- Diagnostic Findings: High PaCO₂, high bicarbonate (compensatory), compensated pH: 7.35–7.4, decompensated pH: <7.33.
Respiratory Alkalosis:
- Causes: Hyperventilation.
- Effects: Decreased PaCO₂.
- Compensatory Mechanism: Kidneys excrete less hydrogen and reabsorb less bicarbonate.
- Diagnostic Findings: Low PaCO₂, low bicarbonate (compensatory), compensated pH: 7.4–7.45, decompensated pH: >7.47.
Metabolic Acidosis:
- Causes: Diarrhea, renal failure, diabetic ketoacidosis, tissue hypoxia.
- Effects: Decreased bicarbonate.
- Compensatory Mechanism: Rapid, deep respirations, increased bicarbonate absorption by kidneys.
- Diagnostic Findings: Low bicarbonate (compensatory), low PaCO₂, compensated pH: 7.35–7.4, decompensated pH: <7.33.
Metabolic Alkalosis:
- Causes: Vomiting, excessive antacid use.
- Effects: Increased bicarbonate.
- Compensatory Mechanism: Slow, shallow respirations, reduced bicarbonate absorption by kidneys.
- Diagnostic Findings: High bicarbonate (compensatory), high PaCO₂, compensated pH: 7.4–7.45, decompensated pH: >7.47.

More Information
Acid-base imbalances can have critical implications for cellular function and overall health. Understanding the causes and compensatory mechanisms helps in effective diagnosis and treatment.
Tips
A common mistake is confusing the compensatory mechanisms, often mixing up respiratory and renal responses. Always match the correct system to the primary imbalance.
