The technology monitors the patient's heart and respiratory rate, temperature, blood pressure and blood oxygen saturation. This data is combined to produce a second-by-second picture of the patient's condition, said Matthew Walls, chief executive of Oxford BioSignals.
'By fusing signals from these five vital signs we get an overall representation of the patient's condition and can see early indications of deterioration,' he said.

Last week the system began a 10-month trial on between 250 and 350 patients in three trauma units at an
