P118 What oxygen target saturation ranges are currently prescribed for non-hypercapnic patients in UK hospitals and what target ranges would respiratory registrars prefer to use?

P118 Figure 1ConclusionsAlthough most UK hospitals use a target oxygen saturation range of 94–98% in the non-hypercapnic population, the preference among the respiratory registrars surveyed was for an alternative strategy (most commonly a target saturation of 92–96%). This suggests a perception among clinicians that more conservative target saturations are non-harmful to these patients, but at present the evidence supporting this is lacking. The UK-ROX and Mega-ROX trials are currently recruiting and aim to evaluate conservative versus standard oxygen saturation targets in mechanically ventilated critically ill patients. Once published these trials will hopefully give us a more concrete basis upon which to make recommendations in this important area.
