Abstract

High-flow nasal cannula (HFNC) oxygen therapy is used widely for hypoxemic respiratory failure. However, it is unknown whether the use of HFNC is compatible with retaining the ability to eat and drink of patients with end-stage respiratory diseases as a part of palliative care. A retrospective study was conducted on subjects with hypoxic respiratory failure due to end-stage respiratory diseases, including interstitial pneumonia and malignant respiratory diseases, who were treated with HFNC or reservoir mask oxygen therapy and died with do-not-resuscitate (DNR) and do-not-intubate (DNI) status. We compared the duration of eating solids and drinking liquids and clinical variables in the HFNC group with those in the reservoir mask group. The data from a total 43 subjects including 20 with HFNC and 23 with a reservoir mask were analyzed. Fitting HFNC to subjects temporarily improved oxygenation. Durations of survival, eating solids, and drinking liquids in the HFNC group were significantly longer than those in the reservoir mask group. No significant adverse effects were observed in either group. In conclusion, the use of HFNC led to prolonged survival while preserving the ability of oral intake in patients with DNR and DNI status.
