遇到心搏骤停者，你会心肺复苏和使用AED吗？｜科普时间

Core Points - The article emphasizes the critical importance of timely intervention in cases of cardiac arrest, highlighting the "golden 4 minutes" for effective resuscitation [1] - It outlines the steps for performing cardiopulmonary resuscitation (CPR) and the use of Automated External Defibrillators (AEDs) to improve survival rates [10][11] Group 1: CPR Steps - Step 1: Ensure the safety of the scene for both the rescuer and the victim [2] - Step 2: Assess the victim's responsiveness and breathing by checking for reactions and observing chest movements [4] - Step 3: Call emergency services (120) and request an AED [5] - Step 4: Perform chest compressions at a depth of 5-6 cm and a rate of 100-120 compressions per minute [6] - Step 5: Open the airway using appropriate techniques, especially if spinal injury is suspected [7] - Step 6: Administer mouth-to-mouth ventilation after 30 compressions, ensuring proper technique [8] - Signs of successful CPR include the return of spontaneous breathing and normal skin color [9] Group 2: AED Usage - AED is a portable device designed for emergency use, capable of analyzing heart rhythms and delivering shocks if necessary [10] - Early use of AED can significantly increase survival rates, with a 90% success rate if used within the first minute of cardiac arrest [10] - The steps for using an AED include turning it on, applying electrode pads, analyzing heart rhythm, and delivering a shock if indicated [12][13][15][17] - AEDs will automatically reanalyze the heart rhythm every 2 minutes and guide the rescuer through the process [19]
