Portable Oxygen Concentrator System and Method Including Concentrated Oxygen Flow Delivery
First Claim
1. A portable oxygen concentrator system adapted to be readily transported by a user and for delivering oxygen to lungs of the user, comprising:
- a rechargeable energy source;
a concentrator powered by said rechargeable energy source and adapted to convert ambient air into concentrated oxygen gas for said user; and
a control unit that controls the concentrator to deliver a flow rate based on at least one of a Body Temperature Pressure Dry (BTPD) condition, a Body Temperature Pressure Saturated with water (BTPS) condition, and a condition between BTPD and BTPS, where relative humidity is 0-100%, to maintain a constant fraction of inspired oxygen (FI02) in the lungs of the user, wherein the portable oxygen concentrator system weighs 4-20 pounds.
