High voltage resistors are one of the necessary passive electronic components in AED, playing an important role. Now let’s take a look at why.
Firstly, let’s understand what AED is.
AED stands for Automated External Defibrillator, is a portable medical device designed to provide emergency treatment for sudden cardiac arrest. It plays a crucial role in delivering a controlled electric shock to the heart, aiming to restore a normal heart rhythm. Key components of an AED include electrodes, which are attached to the chest to deliver the electric shock, and a resistor that helps control the energy levels of the shock. AEDs are user-friendly and often used by bystanders or first responders in emergency situations to improve the chances of survival for individuals experiencing sudden cardiac arrest.

High Voltage Generator/Discharge is an important component of AED, plays a crucial role in the device’s functionality. The main purpose of the high-voltage generator is to convert the low-voltage direct current (DC) power from the AED’s internal battery into a higher voltage suitable for defibrillation. This process involves stepping up the voltage to levels necessary for delivering an effective electrical shock to the heart.
The high-voltage discharger, on the other hand, is responsible for releasing the stored electrical energy in a controlled and targeted manner when a shock is required. It ensures that the energy is delivered through the defibrillation pads or electrodes placed on the patient’s chest, allowing the electric current to flow through the heart and potentially restore normal cardiac rhythm.
Together, the high-voltage generator and discharger in the AED form a critical component in the device’s ability to analyze the patient’s heart rhythm, determine the need for defibrillation, and deliver a properly calibrated electrical shock when necessary for the treatment of sudden cardiac arrest.
High Voltage Resistors plays a crucial role in the high voltage generator / discharge circuit. Their primary function is to control the flow of current, regulate the charging of the capacitor, and and contribute to the overall safety and efficacy of the defibrillation process.
