10 . Guidelines on How to Use AED
An automated external defibrillator (AED)is a device that is strongly recommended to use in time to analyze the heart rhythm, provide electric shock when necessary and save life when SCA (Sudden Cardiac Ares) patient is discovered whose heart unexpectedly stops beating without any warning.
1. Check the patient’s condition, call for help and look for an AED:
If a person collapses in your presence, he or she has likely experience shock or fainting due to SCA, consistently pulseless, unresponsive and not breathing. Then call for medical help immediately and let the patient lie flat on the ground and ask someone nearly to get an AED. Place the AED net to the victim’s left ear, switch on the power and quickly check if the machine and accessories are working property. Voice instructions will sound.
2. Attaching the AED pads
Attach the AED pads to the designated locations of the victim’s bare chest following the animation and voice prompts. The rule of anterolateral AED pad placement for adults: the right pad is placed on the upper right side of the chest, while the left pad is on the lower let side, 7cm below the left armpit. For children under 8, the anterior pad should be placed lo the middle point of the line connecting the two nipples, and the posterior pad on the opposite side of the back.
3. Analysis of the heart rhythm
Insert the electrode pads wires into the AED host device. Press the “Analyse” key and it will automatically analyze the patient’s heart rate to determine the necessity of an electric shock. Never touch the victim during this process. Even a slight touch can affect the analysis. Upon completing the analysis (S-15 seconds). AED will recommend whether to perform defibrillation.
4. Delivering a shock
If an AED shock is required, then a fully automatic APD will ask you to step back and deliver the electric shock automatically. In the case of a semi-automatic AED device, you need to press a button to deliver the shock. If the effective heart rhythm is not restored, the operator should conduct CPR (心肺复苏), and then analyze the heart rhythm again. Repeat until emergency medical personnel arrive.
