Metabolic Alkalosis and ABG Interpretation

Metabolic alkalosis occurs when bicarbonate levels rise or hydrogen ions are lost, causing the blood pH to increase and the body to compensate by slowing ventilation. 🟥ABG Interpretation [Full Guide] ➜ ➜ ➜ http://bit.ly/2YYavvh 🟧ABG Interpretation [Book] ➜ ➜ ➜ https://amzn.to/3YAnq38 🟦ABG Interpretation [Free Course] ➜ ➜ ➜ https://bit.ly/3WCgjWZ 🟪ABG Practice Questions [Quiz] ➜ ➜ ➜ https://bit.ly/3NkkDZ4 Metabolic alkalosis is an acid-base disorder caused by a primary increase in bicarbonate, or HCO₃⁻, or a loss of hydrogen ions. This causes the blood pH to rise above the normal range. On an arterial blood gas, metabolic alkalosis is identified by a pH above 7.45 and an HCO₃⁻ level above 26 mEq/L. PaCO₂ may also be elevated if respiratory compensation is present. The main causes include a direct gain of bicarbonate or a loss of acid from the body. Bicarbonate can increase from excessive antacid use or bicarbonate administration. Acid loss often occurs through prolonged vomiting or nasogastric suction, where gastric acid is removed from the body. Diuretic use, especially loop diuretics such as furosemide, can also contribute by causing volume depletion and electrolyte loss. Symptoms are often related to associated electrolyte imbalances, especially low potassium and low calcium. Patients may experience muscle cramps, twitching, dizziness, lightheadedness, numbness, tingling, weakness, fatigue, hypoventilation, or arrhythmias. Severe or prolonged cases can become clinically significant, especially in patients with underlying cardiac or respiratory disease. The respiratory system attempts to compensate by slowing ventilation. This allows CO₂ to accumulate, which increases carbonic acid and helps lower the pH toward normal. However, this response is limited because excessive hypoventilation can lead to hypoxemia. For this reason, respiratory compensation in metabolic alkalosis may be incomplete, especially in critically ill or hypoxic patients. Treatment focuses on correcting the underlying cause. This may include stopping vomiting, discontinuing or adjusting diuretic therapy, giving normal saline, replacing potassium, and addressing chloride depletion or hormonal abnormalities. Clinicians should always assess volume status, potassium, chloride, and the degree of respiratory compensation when evaluating metabolic alkalosis. 🟥ABG Interpretation [Full Guide] ➜ ➜ ➜ http://bit.ly/2YYavvh 🟧ABG Interpretation [Book] ➜ ➜ ➜ https://amzn.to/3YAnq38 🟦ABG Interpretation [Free Course] ➜ ➜ ➜ https://bit.ly/3WCgjWZ 🟪ABG Practice Questions [Quiz] ➜ ➜ ➜ https://bit.ly/3NkkDZ4 ————— 📘 FREE STUFF ▪ Free Cheat Sheets 👉 https://bit.ly/3IKenWk ▪ TMC Practice Exam 👉 http://bit.ly/2XlwASL 📗 PASS THE BOARD EXAMS ▪ CSE Boost Course 👉 https://bit.ly/3VBwSB2 ▪ TMC Test Bank 👉 https://bit.ly/3QNqwLX ▪ TMC Exam Hacks 👉 https://bit.ly/3iLmVS2 ▪ Daily TMC Practice Questions 👉 https://bit.ly/4cYnOxl ▪ TMC/CSE Bundle (Save $) 👉 https://bit.ly/3VLSyuo 📕 MORE FROM RTZ ▪ Test Bank (Free) 👉 http://bit.ly/2Kp73ln ▪ Glossary 👉 https://bit.ly/3g6s4Pj ▪ About Us 👉 http://bit.ly/2Xgk5YH ▪ Testimonials 👉 http://bit.ly/2x7b5Gl 🌐FOLLOW US ▪ Instagram 👉 http://bit.ly/2FhF0jV ▪ X 👉 http://bit.ly/2ZsS6T1 ▪ Facebook 👉 http://bit.ly/2MSEejt 🚑MEDICAL DISCLAIMER This content is for educational and informational purposes only.
