Many individuals require short-term and long-term oxygen therapy. These users experience discomfort and problems with the standard nasal cannula that are compounded by issues with oxygen sources being heavy with limited supply and tubing getting tangled, kinked, or not providing enough mobility. The objective of this project was to address ergonomic issues with oxygen therapy devices to increase the ease of use for healthcare workers, patients, and families. By following the engineering design process, a prototype was developed for a nasal cannula with interchangeable prongs. The new design allows users to select a prong size that is more comfortable for them.
