Semi-Automatic AED

Semi-Automatic AEDs operate similarly to fully automatic ones, with one fundamental difference: they require the user to initiate the shock. Like fully automatic AEDs, these devices analyze the patient's heart rhythm through attached electrode pads. If a shockable rhythm is detected, the device prompts the user to press a button to administer the shock. This added step ensures that the shock is only delivered when the user determines it is appropriate.

Semi-automatic AEDs are commonly deployed in public spaces, workplaces, and environments where trained personnel are more likely to be present. After attaching the electrode pads, follow the voice prompts, and when prompted, press the shock button to deliver the life-saving treatment.


Pediatric AEDs

Pediatric AEDs are specialized defibrillators designed explicitly for children. Children have smaller body sizes and different energy requirements than adults. Pediatric AEDs deliver lower energy shocks tailored to the needs of pediatric patients. These devices come with pediatric-specific electrode pads and are equipped with algorithms that adjust the energy levels for child-sized bodies.

Proper placement of the pediatric pads on the child's chest is essential. Follow the device's voice prompts and visual cues, ensuring that the pediatric AED is in pediatric mode, guaranteeing the safe and effective delivery of defibrillation to pediatric patients during emergencies.


Professional AED

Professional AEDs are advanced defibrillators used by healthcare professionals and first responders. These devices offer a wide array of features, including detailed cardiac monitoring, data recording, and advanced settings for medical experts to fine-tune the treatment. Healthcare professionals receive specialized training to operate professional AEDs effectively. When deployed, these AEDs provide comprehensive data about the patient's heart rhythm and other vital signs. Medical personnel analyze this data to make informed decisions about defibrillation and subsequent medical interventions, ensuring the highest level of care for patients in critical conditions.


Wearable AEDs

Wearable AEDs are innovative devices worn by individuals at risk of sudden cardiac arrest. These compact, discreet devices continuously monitor the wearer's heart rhythm. The wearable AED automatically administers a shock to restore normal heart rhythm if an irregular heartbeat is detected.

Follow the manufacturer's guidelines for proper device placement, ensuring that the wearable AED is in contact with the skin to monitor the heart effectively. Wearable AEDs offer continuous, unobtrusive protection, allowing individuals at risk to lead their daily lives with the confidence that life-saving intervention is immediately available if needed.
