AEDs are not limited to use by medical professionals. Individuals who have been trained and certified in CPR and AED use, or have completed Basic Life Support (BLS) or Advanced Life Support (ALS) courses, are qualified to operate an AED. Those without any emergency training should follow the guidance of emergency dispatch personnel when using the device. 

A semi-automatic AED requires the rescuer to press the shock button after analysis, while a fully-automatic AED delivers the shock automatically if needed. 

Yes. For children under 8 years old or weighing less than 25 kg, the AED’s child mode should be used. If the child’s age is uncertain, the adult mode can be used. 

1）If there is standing water around the patient (e.g., pools, floodwater), move the patient to a dry area immediately to avoid electric shock to the rescuer or the patient due to current conduction through water. If moving the patient is not possible, try to place insulating materials like clothing or towels underneath them, or dry the contact areas as much as possible.
2）If the patient's chest is wet (from sweat, rain, or other liquids), quickly dry the area with a towel or clothing to ensure the electrode pads adhere properly to the skin.
3）When using the AED in the rain, try to shield the patient's chest with waterproof materials (such as plastic sheeting) and perform the operation quickly. The AED has a certain level of water resistance, but ensuring good contact of the electrode pads is the top priority.
4）If the patient is submerged in water (e.g., in a pool or bathtub), remove them from the water completely and dry their body thoroughly before using the AED. 

Yes. Pacemakers or implantable defibrillators are usually placed under the left collarbone, either beneath the pectoral muscle or under the skin. Therefore, when using an AED, simply avoid placing the electrode pads directly over the implanted device.    

Yes, but the patient should be kept as stable as possible to minimize motion interference.    

Yes. Our AED provides voice guidance in multiple languages and supports automatic CPR coaching.    

The AED is reusable. The main unit typically has a service life of 8–10 years, while the battery and electrode pads need to be replaced regularly.    

Yes, the electrode pads contain a large amount of conductive gel, which is consumed and poses hygiene concerns after use, making them unsuitable for reuse. The typical shelf life of electrode pads is 2-3 years, with some models having a shelf life of up to 5 years. They should be replaced with new pads once expired.    

Yes, the AED can store electrocardiogram (ECG) and operation records for medical personnel to analyze.    

1）Effectiveness: Sufficient energy is key to terminating ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Biphasic waveform technology can achieve results comparable to high-energy monophasic waveforms at lower energy levels, while also reducing myocardial damage.
2）Safety: Excessive energy can damage myocardial tissue, and modern AEDs have significantly reduced this risk through biphasic waveforms.
3）Medical Consensus: The recommended initial energy for biphasic AEDs is 120-200 joules. If the first shock is ineffective, subsequent shocks can be delivered at the same or slightly higher energy levels. Monophasic AEDs require higher energy (e.g., 360 joules) but are gradually being phased out.    

Yes, it needs to be regularly checked for battery, electrode pad expiration, and overall device status (typically once a week or month).   

Regularly check the indicator light (usually green), listen for the self-check startup beep, and ensure there are no expiration warnings.  

Typically every 2-5 years, depending on the model. The device will issue a warning when the battery is low.
