Electrolyte Balance in Critical Care Nursing | Sodium, Potassium & Calcium Regulation

Electrolyte balance is a cornerstone of advanced nursing practice and plays a critical role in maintaining cellular function, hemodynamic stability, and neuromuscular activity. Even minor disturbances in electrolyte levels can lead to life-threatening complications, particularly in postoperative, critically ill, and renal patients. In this video, we provide a comprehensive postgraduate-level explanation of electrolyte balance, focusing on the physiology, hormonal regulation, and clinical relevance essential for MSc Nursing students and practicing nurses. Key electrolytes including sodium, potassium, calcium, magnesium, and chloride are discussed in detail, with emphasis on their compartmental distribution and regulatory mechanisms. The session also explores the role of aldosterone, antidiuretic hormone (ADH), and the renin–angiotensin–aldosterone system (RAAS) in sodium–water balance, along with the cardiovascular and renal influences that maintain electrolyte homeostasis. 🎯 This video is especially useful for: Nursing students Critical care and ICU nurses Medical–Surgical Nursing preparation Postoperative and renal nursing practice Teaching faculty and nurse educators 📌 Topics Covered: Concept and importance of electrolyte balance Major body electrolytes and their functions Sodium regulation and water balance Hormonal control: Aldosterone, ADH, RAAS Potassium balance and cardiac implications Calcium homeostasis and hormonal regulation Role of magnesium and chloride Clinical significance for nursing practice 🔔 Subscribe for more nursing lectures 📘 Designed as per advanced nursing curriculum 💬 Comment below if you want case-based electrolyte discussions or exam-oriented revision videos.
