Problems solved by technology

When oxygen needs are not being met, the simple solution is to increase the nasal flow rate, which can lead to uncomfortable drying of the nasal passages and sometimes increased nasal mucosal bleeding

Abstract

A fluid delivery system provides fluid, such as supplementary oxygen, to a patient in response to inhalation. The fluid delivery system includes a valve assembly that is triggered by sensing nasal flow. The system includes a sensor configured to detect flow either directly through the nose and to detect any "flow leakage" through a patient's nasal cavity while mouth breathing. A method for conserved delivery of fluid to a patient that includes sensing such nasal flow is also provided.

Description

technical field [0001] The present invention relates to devices and methods for monitoring and delivering oxygen to a patient, and for effectively protecting the delivery of oxygen to a patient. Background technique [0002] Currently, approximately 1 million patients in the United States receive supplemental oxygen therapy through the Medicare payment system at a cost of approximately $2 billion, with costs increasing approximately 13% per year. ("Long-term supplemental oxygen therapy." Up-To-Date; January 18, 2013. Brian LTiep, MDRick Carter, PhD, MBA). [0003] Most patients receiving long-term supplemental oxygen therapy (LTOT) suffer from chronic hypoxemia due to chronic obstructive pulmonary disease (COPD). There is currently no cure for the disease. However, the adverse effects of chronic hypoxemia can be mitigated by the administration of long-term oxygen therapy (LTOT). Continuous inhalation of low-flow oxygen, typically 2 to 3 lpm (L / min), from a nasal cannula i...
