The study is being supported locally by the NIHR Clinical Research Network South West Peninsula, and sponsored by the Intensive Care National Audit & Research Centre (ICNARC).
Each year, around 184,000 patients are admitted to NHS ICUs and over 30% require help with their breathing using a ventilator (breathing machine).
Giving oxygen through the ventilator is an essential part of this treatment, however the most effective concentration of oxygen that should be administered is not known as both too much, and too little, may cause harm.
The UK-ROX trial is testing an approach known as ‘conservative oxygen therapy’, where a reduced oxygen saturation target is used in critically ill patients. If this is shown to reduce mortality rates compared to the current standard care, the study will recommend immediately changing clinical practice in ICUs throughout the NHS.
Professor Martin added:
“Oxygen is the most common drug we give to our patients on ICU yet we don’t really know how much oxygen to give to patients in order to optimise their recovery. In the past we assumed people needed more oxygen than usual when unwell, thinking oxygen couldn’t be harmful. We now know that giving too much oxygen to patients might cause harm. Given how many patients we treat with oxygen on ICUs every day in the UK, any adjustments that might be delivered from the study have the potential to save thousands of lives.”
