Demand-Type Oxygen Conservation Device for Clinical Oxygen Administration

Oxygen therapy can assist people with acute respiratory distress syndrome, chronic obstructive pulmonary disease, COVID-19, emphysema, sleep apnea, and other respiratory problems to provide them with enough oxygen for regular function and well-being. Patients with severe respiratory disorder may need to receive supplemental oxygen throughout the day, the duration depending on the severity and nature of their disorder. Continuous-flow oxygen devices are the most common means to deliver oxygen for the long term to such patients. However, continuous-flow oxygen devices used in oxygen therapy cannot titrate oxygen according to the patient’s breathing pattern. A considerable amount of oxygen is wasted when oxygen is delivered to the patient during exhalation. Additionally, since 2020, nations all around the globe witnessed a high oxygen demand due to the COVID-19 pandemic. Before the pandemic, many nations had not expected such a large demand for daily oxygen needs. Governments all over the world are expanding their current infrastructure to meet the oxygen demand to expand the availability of clinical oxygen. Thus, traditional continuous-flow systems can be integrated with an oxygen conservation device that can administer oxygen in harmony with the patient’s breathing. It can significantly enhance the effectiveness of continuous-flow devices by controlling the supply of oxygen to patients based on their needs.
