1. Objectives

By the end of the lecture, students should be able to:

• Define CPR.
• Identify components of CPR.
• Understand the indications and steps for performing CPR.

2. Introduction

• Critical Importance: Continuous blood supply (oxygen + nutrients) is vital for cellular function.
• Cardiopulmonary Arrest: Sudden cessation of heart/lung function leads to brain damage within 4–6 minutes and irreversible damage/death after 8–10 minutes.
• CPR: A life-saving technique to restart the heart and maintain circulation/oxygenation until advanced care (e.g., defibrillation) is available.

3. Definition of CPR

• CPR (Cardiopulmonary Resuscitation): Clinical intervention involving chest compressions and rescue breaths to sustain life during cardiac/respiratory arrest.
• Defibrillator: Electrical device used to restart the heart (if available).

4. Goal of CPR

• Maintain adequate circulation.
• Ensure airway patency.
