By Dr. Faiza Assistant Professor of Physiology MBBS (Best Graduate, AIMC Lahore), FCPS (Physiology), ICMT, CHPE, DHPE (STMU), MPH (GC University, Faisalabad), MBA (Virtual University of Pakistan) Description: This comprehensive lecture on Acid-Base Balance provides an in-depth understanding of the body’s regulatory mechanisms for maintaining pH homeostasis. Acid-base imbalances can lead to serious clinical conditions, and understanding these physiological processes is crucial for medical professionals. Learning Objectives: ✔ Compare the role of the three lines of defense in acid-base regulation ✔ Explain the role of the respiratory system in acid-base balance ✔ Describe the renal mechanisms for correcting acidosis and alkalosis ✔ Correlate acid-base disorders with their underlying etiology ✔ Interpret arterial blood gas (ABG) analysis for diagnosing acid-base imbalances ✔ Define the anion gap and explain its clinical significance Key Topics Covered: 🔹 Fundamentals of Acid-Base Chemistry – Definition of acids, bases, buffers, and the pH scale 🔹 Physiological Buffers – Bicarbonate, phosphate, and protein buffer systems 🔹 Respiratory Regulation – Role of CO₂ and ventilation in acid-base balance 🔹 Renal Regulation – HCO₃⁻ reabsorption, H⁺ secretion, and new bicarbonate generation 🔹 Acid-Base Disorders – Metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis 🔹 Clinical Applications – Case studies on ABG interpretation and diagnosing acid-base imbalances Who Should Watch? ✅ Medical students (MBBS, BDS) ✅ Postgraduate trainees in Physiology, Medicine, and Critical Care ✅ Medical educators seeking a structured approach to teaching acid-base balance ✅ Healthcare professionals interested in mastering ABG interpretation 📌 Includes real-life clinical case discussions, ABG interpretation exercises, and graphical illustrations for better understanding. 📥 Download Now & Enhance Your Understanding of Acid-Base Homeostasis!
