Video Summary:
Welcome to **Clinical Crash Course**! In Module 3, we enter the Emergency Room. We are facing "Acute Decompensated Heart Failure" (ADHF). Dr. Collins breaks down the hemodynamic profiles (Cold vs Warm, Wet vs Dry) and guides you through the life-saving **LMNOP Protocol**. You will learn why "Oxygen" comes first, why "Morphine" is controversial, and how Nitrates save lives by reducing preload. We also cover the "Flash Pulmonary Edema" scenario.

Key Topics Covered:
*The Clinical Picture:* The patient is drowning in their own fluids.
*Hemodynamic Profiles:*
*Warm & Wet:* Most common (Perfusion OK, Congestion High).
*Cold & Wet:* Cardiogenic Shock (The most dangerous).
*The LMNOP Protocol:*
*L (Lasix):* IV Furosemide to dump fluid (Vasodilation first, diuresis second).
*M (Morphine):* Use with caution! (Reduces anxiety but can depress respiration).
*N (Nitrates):* Venodilation to reduce Preload immediately.
*O (Oxygen):* Keep Saturation over 90 percent. Use BiPAP if needed.
*P (Position):* Sit them up (legs down) to use gravity.
*DO NOT GIVE:* Beta-Blockers in acute decompensated failure! (They reduce contractility).

*UP NEXT:* The patient is stable. Now what? Watch Module 4 for the Chronic "Fantastic Four" drugs!
