Laser shock

A device that uses laser spectroscopy to monitor a patient's breath and more specifically their oxygen usage could be a boon for intensive care where patients with shock at serious risk of organ failure of their falling blood pressure leads to an inadequate supply of the vital substances reaching all body tissues. Peter Robbins of the Department of Physiology, Anatomy and Genetics and chemists Grant Ritchie and Gus Hancock of the University of Oxford, UK, developed the new technology. "This is the culmination of many years of development and it has finally come to fruition," says Robbins, who led the research. "It is exciting for us to be able to offer something to doctors that has the potential to improve significantly the care of very sick patients.
