ZOLL Medical
The aforementioned Zenix is the latest device from ZOLL, a leading manufacturer of monitor/defibrillators.
In September 2025, the device was given Federal Drug Agency (US Food and Drug Administration) approval, clearing it for EMS use across the United States.
Zenix is built on user feedback and features an 8.4-inch LCD touchscreen which can display most functions within three taps of the screen. A physical knob is also fitted.
To reduce downtime during upgrades, the device features pods containing the essential hardware. This “plug-and-play” system allows ZOLL’s ExpertCare Field Service technicians to simply replace old pods with the new updated equipment.
The device is designed for all ages but has been designed to recognise when it is attached to a paediatric patient, so that it automatically lowers energy levels prior to defibrillation.
It also adjusts alarms to paediatric settings and displays critical information via the dedicated paediatric CPR Dashboard display.
Zenix features ZOLL’s See-Thru CPR, which enables medical personnel to view underlying rhythm without stopping compressions.
An AED analysis algorithm adjusts to paediatric parameters, and Zenix provides constant current pacing, which ZOLL says is “more effective for treating bradycardia with less current”, adding: “Zenix delivers advanced, tailored support to help improve paediatric resuscitation.”
Post-treatment of patients, Zenix automatically sends code data to ZOLL’s RescueNet CaseReview debriefing software.
The software displays detailed, snapshot data covering the patient’s journey while connected to the device. This allows for easy review and provides training materials for future events.
New rotorcraft mean new challenges, but also new possibilities. Looking ahead, how will the arrival of eVTOL platforms impact HEMS operations? Will OEMs provide their own off-the-shelf capabilities or will the major players continue to develop these aircraft?
As medical technology advances, particularly in the world of trauma and immediate response, it is only logical to expect HEMS capabilities to advance too.
