I take an AED course today; the examination is attended at the same day after the course as well. I think I can't pass the exam because I was too nervous for the exercise. We need to show the steps to use the AED machine and the steps to show CPR procedures. I forget the CPR procedures for a long time because I attended the CPR exam in Jan, nearly half year ago.
But anyway, I gain some experience from the course that is related to our heart. Some electric circuit is generated by the heart itself to maintain the normal heartbeat for the blood flowing from the lungs and then to and from the whole body. If no electric circuit is failed to generate, the heart will beat irregularly, the AED machine is needed to stop the il-regular heart beat in order to generate the electric circuit by the heart itself successfully.
No pain no gain, it is worth to pay $250 dollars for the course.
Write on 19 July,
I've passed the AED test and taken the certificate few days ago. Happy and Surprise!
