Caudwell Extreme Everest is a research project coordinated by the UCL Centre for Altitude, Space and Extreme environment medicine (CASE). Doctors and scientists study human volunteers to breaking point in extreme environments to increase the understanding of critically ill patients.
The group placed a research team on the summit of Mount Everest in May 2007 and made the first ever measurement of the level of oxygen in human blood at 8400m, on the balcony of Everest. This was the centrepiece of an extensive and continuing programme of research into hypoxia (low oxygen levels) and human performance at extreme altitude aimed at improving the care of the critically ill and other patients where hypoxia is a fundamental problem.
The VRI was one of the key products tested in extreme conditions and photos will be collected for Smiths Medical for use at a later date. This is a very exciting project that Smiths Medical are heavily involved in. You can read more about Cauldwell Extreme Everest by taking a look at their website click here.
