The document outlines the basic steps of life support (BLS) including assessment, airway management, breathing, circulation, and defibrillation. Step 1 involves checking for unresponsiveness and calling for help. Step 2 is opening the airway and checking breathing, providing positive pressure ventilation if needed. Step 3 involves assessing circulation by feeling the carotid pulse and performing chest compressions at a rate of 100 per minute with a compression to ventilation ratio of 15:2 if no pulse is detected. Foreign object removal techniques like abdominal thrusts and finger sweeps are described. Oxygen therapy, airway devices, endotracheal intubation and the emergency cart are also summarized.

3. Step 1: Check for Unresponsiveness Check for unresponsiveness ---”Are you all right?” Call for help --- “6969” --- “119” Unrespond

4. Step 2: Open A irway Upper airway obstruction by the tongue & epiglottis “ Head tilt- chin life” “ Jaw thrust” If suspected head trauma

12. Check for unresponsiveness Access airway Signs of airway obstruction? Access breathing Signs of inadequate breathing? Access pulse Pulse absent? Open airway Positive ventilation Administration oxygen Chest compression Ready for defibrillation Follow ACLS protocol Yes Yes Yes No No Check BP Recovery position No Initial assessment

13. Emergency cart: EKG monitor and defibrillator Drugs, laryngoscope, light, oral or nasal airways

14. Airways: Oropharyngeal airway Nasopharyngeal airway

15. Ambu bag: “ E-C” technique

16. Oxygen therapy: Nasal cannula Simple mask Ventri mask Non-rebreathing mask FiO 2 24% 100%

17. Endotracheal tube intubation: Layngoscope: Check light Endotracheal tube: Male: 7.0, 7.5, 8.0 Female: 6.5, 7.0, 7.5 Test cuff “ sniffing” position Oral-pharyngeal-tracheal axis

18. Endotracheal tube intubation: Vocal cord Lift forward & upward Sellick maneuver Length: 19~23cm Cuff Check position: stethoscope, CXR
