Chronic hypoxic respiratory failure is associated with certain conditions such as chronic obstructive pulmonary disease and congestive heart failure. As chronic hypoxic respiratory failure progresses, supplemental oxygen requirements can exceed the capacity to deliver the gas using practical, portable equipment, limiting mobility and participation in physical therapy and cardiopulmonary rehabilitation.
The current system by which oxygen is delivered is inherently flawed in that humans do not breathe a continuous stream of air. Pulsed delivery systems can sense a patient’s inspiration and then deliver oxygen, but these systems are expensive, and limited in terms of how much oxygen they can supply.
Dr. Pandey and Dr. Zafar have invented a high dose oxygen system that allows a patient to breathe oxygen directly from an expandable-collapsible reservoir that collects oxygen supplied by continuous flow. This system allows the user to draw high volumes of oxygen rich gas from the reservoir using their own inspiratory effort.
