AED Awareness.pdf
The document outlines the anatomy and physiology of the heart, detailing the various valves and blood circulation pathways. It includes instructions for the use of an automated external defibrillator (AED), such as how to prepare the patient and administer shocks safely. The document emphasizes the importance of troubleshooting heartbeats with an AED during emergencies.

Pump the rest of blood into ventricles ❑ Ventricular systole – contraction of ventricle. Pump blood into systemic circulation ❑ Ventricular diastole – ventricles and atria relaxed

- 18. HOW TO USEAED
- 20. 1. TURN ONTHE AED p/s: to turn OFF, press the button for 2 secs
- 21. 2. EXPOSE CHEST •Remove clothing from patient chest • Make sure chest is clean and dry
- 22. 3. TOATTACH PADS •Tear open the pads from packet • Peel adhesive pads from blue liner
- 23. 3A. ATTACH PADS 1.One pad goes on the upper right chest below collarbone. 2. One pad goes on lower left side chest wall. 3. For Kid, put at front & back of the kid
- 24. 3A.AED AND PACEMAKER •Pacemakers are located under the collarbone on right or left side of chest • If located on right side place AED pad 1 inch below pacemaker • Continue with AED prompts
- 25. 3A.AED AND BRAS •Many bras contain metal (Clips, underwire) • Remove / cut bra if AED pads will touch the metal
- 26. 3A.AED AND JEWELRY •Ignore jewelry if it will not touch AED pad • If in the way push jewelry to side of neck away from AED pads. • Do not waste time removing jewelry
- 27. 3A.AED AND WETPERSON • Dry off victims chest (and back if a child under age 8.) • Attach pads following manufacturer directions • The rest of the victim does not need to be dry. • AEDs can be used on wet surfaces and snow so long as patient is dry and not in a puddle of water.
- 28. 4. STAY CLEAR •Make sure nobody , including yourself, is touching the victim. Say “Everyone stand clear!”
- 29. 5. DELIVER SHOCK IfAED Prompts a Shock • Make sure no one is touching victim • Push the “shock” button
- 30. 6. AFTER SHOCK •Do not turn off AED…. • It is now safe to touch Pads and patient
- 31. 7. PERFORM CPR •After shock, or if no shock is advised, continue CPR. • Every 2 minutes follow the AED prompts • Stop CPR if you see signs of life – (breathing, movement.)
