Patho 101 Unit 3: Lungs, Fluid, Electrolyte, and Acid-Base Balance

Level up your patho knowledge! In this episode of The Patho Playbook, we blast through three core units and finish with a Boss Battle ABG case study. 🫁 LEVEL 1 — The Lungs Obstructive vs. restrictive lung disease, emphysema vs. chronic bronchitis, and how ARDS knocks out gas exchange. 💧 LEVEL 2 — Fluids & Electrolytes Why hypernatremia shrivels cells, the 4 possibilities of edema, and aldosterone's role in expanding volume. ⚗️ LEVEL 3 — Acid-Base Physiology Normal pH range, why proteins fail outside it, and how lungs (fast) and kidneys (slow) compensate. ⚔️ BOSS BATTLE — ABG Case Study Blood pH 7.14, PCO2 55, HCO3- 27 — walk through the 3-step method to identify Respiratory Acidosis and predict compensation. Made for nursing, pre-health, and A&P students who want pathophysiology to actually stick. ⏱️ TIMESTAMPS 0:00 Intro 0:30 The 3 Levels + Boss Battle roadmap 0:45 Level 1: Obstructive vs. Restrictive – The Great Airway Divide 1:30 Can't get air OUT vs. can't get air IN 2:00 Emphysema vs. chronic bronchitis 2:30 The inflammatory/fibrotic cascade 3:00 ARDS breakdown 3:45 Level 2: Hypernatremia — the shriveling cell 4:15 Edema: the 4 possibilities 5:00 Aldosterone, the saltwater hormone 5:45 Level 3: Acid-Base Physiology fundamentals 6:15 Normal pH range & why it matters 6:45 Compensation: lungs (fast) vs. kidneys (slow) 7:15 Finding the primary imbalance 7:30 Boss Battle: the ABG case 7:45 3-step ABG analysis → Respiratory Acidosis 8:30 Respiratory acidosis: cause, signs, compensation 9:00 Cliffhanger — will HCO3- go up or down? #Pathophysiology #NursingSchool #NCLEX #ABGInterpretation #AcidBaseBalance #ARDS #PreNursing #APClass
