Study Notes
Automated External Defibrillator (AED) Use
- AEDs analyze heart rhythms and deliver electric shocks to treat ventricular fibrillation, a common cause of cardiac arrest.
- Ventricular fibrillation is characterized by disorganized electrical activity in the heart's main pumping chambers.
- Defibrillation aims to stop this disorganized activity and restore the heart's normal rhythm.
- AEDs are designed to be user-friendly and prevent accidental misuse.
- AEDs are becoming increasingly common in public spaces.
AED Usage Steps
- Let the AED analyze the heart rhythm.
- If the AED displays "Check Electrodes," ensure proper electrode contact and reposition if necessary, particularly if the chest is hairy.
- If the AED indicates "Shock," ensure nobody is touching the patient before pressing and holding the shock button.
- After delivering a shock, immediately resume CPR for two minutes, beginning with chest compressions.
- Repeat steps 1-4 as needed.
AED Self-Assessment Questions and Answers
- Question 1: What does AED stand for? Answer: Automated External Defibrillator
- Question 2: A patient with a pacemaker or AICD (Automatic Implantable Cardioverter-Defibrillator) bulge under the skin: Avoid placing AED pads over the bulge.
- Question 3: After an AED indicates "Shock," immediately clear the person and deliver the shock.
- Question 4: Following shock delivery, resume CPR starting with chest compressions.
Adult BLS Self-Assessment Questions and Answers
- Question 1: For an unresponsive person who collapses, immediately call 911/EMS.
- Question 2: To open the airway of a person who may have a neck injury, use the jaw thrust maneuver.
- Question 3: If a patient's pulse returns but they aren't breathing after CPR, ventilate at 10-12 breaths per minute.
Basic Life Support (BLS) Flowchart
- If there is no pulse and no normal breathing or only gasping, begin CPR cycles of 30 compressions and two breaths until an AED arrives.
- Once the AED arrives, assess for a shockable rhythm.
- If the rhythm is shockable, administer one shock and then return to CPR immediately for two minutes. Repeat if necessary and assess the rhythm every two minutes.
- If the rhythm is nonshockable, resume CPR immediately for two minutes and reassess the rhythm every two minutes, until advanced life support (ACLS) arrives or the patient shows signs of circulation return.
