🎯 MedQ Lecturer

Respiratory alkalosis is a type of acid-base imbalance that occurs when there is excessive loss of carbon dioxide (CO₂) from the body due to hyperventilation. When CO₂ levels drop, carbonic acid (H₂CO₃) decreases, causing the blood pH to rise above 7.45, making it more alkaline.

🫁 Causes

Anxiety or panic attack

Fever

Hypoxia (high altitude, pulmonary embolism)

Mechanical over-ventilation


🔍 Signs & Symptoms

Light-headedness or dizziness

Tingling in fingers or around mouth

Muscle cramps or tetany

Palpitations

Confusion

🧠 Compensation

The kidneys compensate by excreting bicarbonate (HCO₃⁻) to bring pH back toward normal.

💊 Management

Treat the underlying cause (e.g., anxiety, hypoxia)

Encourage slow breathing or breathing into a paper bag (if due to anxiety)

Correct oxygen levels in hypoxic conditions.
