Nam, Bae, Park, Ko, Park, Park, and Yim: Development of Nursing Practice Guidelines for Non-humidified Low Flow Oxygen Therapy by Nasal Cannula

Abstract

Purpose

The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice.

Methods

A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines.

Results

Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort.

Conclusion

The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).

*Level type

Level I: experimental study, randomized controlled trial (RCT), systemic review of RCTs with or without meta-analysis; Level II: quasi-experimental studies, systematic review of a combination RCTs and quasi-experimental studies, or quasi-experimental studies only, with or without meta-analysis; Level III: non-experimental study, systematic review of a combination of RCTs, quasi-experimental, and non-experimental studies, or non-experimental studies only, with or without meta-analysis, qualitative study of systematic review of qualitative studies with or without meta-synthesis; Level IV: opinion of respected authorities and/or reports of nationally recognised expert committees/consensus panels based on scientific evidence; Level V: evidence obtained from literature reviews, quality improvement, program evaluation, financial evaluation, or case reports, opinion of nationally recognized expert(s) based on experimental evidence
