The investigators found that the risk of death was lower in patients treated with the titrated oxygen compared to high-flow oxygen. “Titrated oxygen treatment reduced mortality compared with high flow oxygen by 58% for all patients and by 78% for patients with confirmed COPD. “¦ These results provide strong evidence to recommend the routine use of titrated oxygen treatment in patients with breathlessness and a history or clinical likelihood of chronic obstructive pulmonary disease in the prehospital setting,” they said.
