CONTROL DEVICE FOR SUPPLYING SUPPLEMENTAL RESPIRATORY OXYGEN

摘要

A system for delivering supplemental oxygen for sub-acute care, the system comprising: a blood oxygen content level sensor (14); a source of supplemental oxygen (20); a valve (26) in fluid communication with the source of supplemental oxygen (20); and a controller (10) capable of operating the valve (26), the controller (10) restricting flow through the valve (26) when the blood oxygen content level measured by the blood oxygen content level sensor (14) is above a desired value.
