ICU is not about diseases.

It is about oxygen delivery, perfusion, ventilation, and time.

Every night in the intensive care unit, patients arrive who were talking minutes earlier… and suddenly start crashing.

In those moments, there is no time to search textbooks.

You must think.

Just Before Flatline is a 150-chapter clinical journey through real ICU thinking. Each chapter recreates a bedside scenario where a patient deteriorates and the intensivist must decide what matters most in the next few minutes.

Through these cases, you will learn:

• How to recognize deterioration before monitors crash
• The ABCDE approach to critical illness
• Shock physiology and bedside differentiation
• Fluid resuscitation and when fluids kill
• Vasopressors, inotropes, and perfusion management
• Ventilator thinking beyond numbers
• Acid-base mastery and hidden mixed disorders
• Lactate interpretation and microcirculatory failure
• Consultant-level clinical reasoning used in real ICUs

This book is designed for:

• MD Medicine residents
• ICU fellows (IDCCM / CTCCM / IFCCM)
• Emergency physicians
• Medical students interested in critical care

Each chapter combines story, physiology, and evidence-based medicine to simulate the pressure of real ICU decision making.

Because in critical care, survival often depends on what happens just before flatline.
