The potential benefits and challenges of the high-flow nasal cannula (HFNC) in homecare settings compared to standard long-term oxygen via nasal low-flow therapy are unclear. Methods: We conducted a prospective monocentric feasibility study at the Department of Respiratory Medicine, University Hospital, Goethe University Frankfurt, Germany. Patients with interstitial lung disease or severe bronchiectasis (including cystic fibrosis) were enrolled into the study. The HFNC was introduced during hospitalization. The patients\u2019 compliance with home use advice and arterial blood gas results were evaluated at a 4\u20136-week follow-up. Results: A total of 12 patients were analyzed. HFNC initiation did not result in a significant improvement of the pO2\/fiO2 (p\/f) ratio. Only 8 out of 12 (66.6%) patients used the HFNC at home after the initial in-hospital initiation. Only 7 of the total 12 patients were using the therapy at a follow-up 3\u20136 weeks after HFNC onset. Two patients died during the observation, resulting in a surveillance mortality rate of 16.7%. Conclusions: The feasibility data showed low adherence to the HFNC at home. The lack of any positive effect on the p\/f ratio may be due to low airflow rates and overall mild hypoxemia compared to patients with severe respiratory failure in the ICU.<\/jats:p>","DOI":"10.3390\/jcm13154525","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T13:14:42Z","timestamp":1722604482000},"page":"4525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Nasal High-Flow Oxygen Therapy in Chronic Respiratory Failure for Homecare Applications\u2014A Feasibility Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6827-9373","authenticated-orcid":false,"given":"Achim","family":"Gr\u00fcnewaldt","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine and Allergology, University Hospital, Goethe University, 60590 Frankfurt, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5193-7755","authenticated-orcid":false,"given":"Gernot","family":"Rohde","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine and Allergology, University Hospital, Goethe University, 60590 Frankfurt, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1159\/000455879","article-title":"Long-Term Oxygen Therapy: Comparison of the German and British Guidelines","volume":"93","author":"Magnet","year":"2017","journal-title":"Respiration"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"674","DOI":"10.1136\/thx.52.8.674","article-title":"Effect of long-term oxygen therapy on survival in patients with chronic obstructive pulmonary disease with moderate hypoxaemia","volume":"52","author":"Gorzelak","year":"1997","journal-title":"Thorax"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Elphick, H.E., and Mallory, G.
