Patent number: 7899507Abstract: A patient monitor has multiple sensors adapted to attach to tissue sites of a living subject. The sensors generate sensor signals that are responsive to at least two wavelengths of optical radiation after attenuation by pulsatile blood within the tissue sites. Multiple data channels and associated quality parameters are derived from the sensor signals. A processor is configured to operate on the channels according to the quality parameters so as to provide a robust oxygen status measurement.Type: GrantFiled: May 3, 2006Date of Patent: March 1, 2011Assignee: MASIMO CorporationInventors: Ammar Al-Ali, Mohamed K. Diab, Massi E. Kiani, Robert James Kopotic, David Tobler

Patent number: 7891355Abstract: A patient monitor has multiple sensors adapted to attach to tissue sites of a living subject. The sensors generate sensor signals that are responsive to at least two wavelengths of optical radiation after attenuation by pulsatile blood within the tissue sites. A patient monitor uses the sensor signals to determine changes in constant oxygen consumption as an indication of changes in metabolism at the tissue cite.Type: GrantFiled: May 3, 2006Date of Patent: February 22, 2011Assignee: MASIMO CorporationInventors: Ammar Al-Ali, Mohamed K. Diab, Massi E. Kiani, Robert James Kopotic, David Tobler

Patent number: 7761128Abstract: A physiological monitor varies perfusion at a tissue site and measures resulting perfusion values and corresponding oxygen consumption values. A constant oxygen consumption relationship between the perfusion values and the oxygen consumption values is characterized, and changes in that relationship are monitored so as to indicate changes in metabolism at the tissue site.Type: GrantFiled: April 13, 2005Date of Patent: July 20, 2010Assignee: MASIMO CorporationInventors: Ammar Al-Ali, Mohamed K.

Patent number: 6898452Abstract: An improved pulse oximeter provides for simultaneous, noninvasive oxygen status and photoplethysmograph measurements at both single and multiple sites. In particular, this multiple-site, multiple-parameter pulse oximeter, or “stereo pulse oximeter” simultaneously measures both arterial and venous oxygen saturation at any specific site and generates a corresponding plethysmograph waveform. A corresponding computation of arterial minus venous oxygen saturation is particularly advantageous for oxygen therapy management. An active pulse-inducing mechanism having a scattering-limited drive generates a consistent pulsatile venous signal utilized for the venous blood measurements. The stereo pulse oximeter also measures arterial oxygen saturation and plethysmograph shape parameters across multiple sites.Type: GrantFiled: September 22, 2003Date of Patent: May 24, 2005Assignee: Masimo CorporationInventors: Ammar Al-Ali, Mohamed K. Diab, Massi E. Kiani, Robert James Kopotic, David Tobler
