Description

A system suitable for real-time measurement of oxygen partial pressure (p02) in respiratory gas (oxigraphy) that is based on oxygen's ability to quench the phosphorescence of a lumiphore is described A description of currently used p02 technologies is provided followed by a description of the luminescence quenching p02 technology. A comparison of the technologies is made. The description of luminescence quenching p02 technology includes the operational theory and the advantages of the use of phosphorescence lifetime as opposed to phosphorescence intensity for p02 measurement. The clinical benefits of oxigraphy as well as a possible space-based application of luminescence quenching p02 technology are proposed
