A portable cooling approach for heatstroke

Published:  01 September, 2015

Caervest is a new technology that delivers rapid core body cooling to victims of heatstroke, cardiac arrest and other conditions. 

Until today stirred ice water baths, intravenous ice-cold saline or pre-chilled pads have produced the most rapid rates of cooling. Caervest is the first portable, immediately active device that can achieve the required depth and extent of cooling needed to treat heat stroke.

In 2014 a London Marathon runner collapsed on the finishing line from a heat related illness and died before he reached hospital as the doctors, medical team and ambulance crew were unable to resuscitate him. During the 2015 London and Brighton marathons, three marathon runners who recorded temperatures above 40°C were treated with Caervest within minutes of collapse.

Caervest is CE certified and is currently being evaluated by medical staff in the military, healthcare and sports sectors and by a number of medical facilities in the US, UK and Australia. The device is intended to form part of every paramedic kit and be used by qualified personnel and first responders attending call outs.

It can be incorporated into standard resuscitation protocols and be carried in an emergency vehicle, cooling smoothly and continuously for at least an hour without needing any attention from the crew.

The device presents no fluid challenge to the heart and allows both CPR and defibrillation to take place.

CAERvest is single-use to minimise infection, is easily transportable, cools the body and enables temperature management to commence even before there is return of spontaneous circulation.

Sir Mark Weinberg, Chairman of Bodychillz, the company behind Caervest, commented: ‘Heatstroke affects millions of people every year and is as serious and deadly as a heart attack. The burden of heat-related illness and cardiac arrest on healthcare systems around the world is such that even a modest improvement in mortality and morbidity following these conditions will have a significant impact on death and the resources required to care for survivors.’
