Patent number: 7260425Abstract: A non-invasive optical sensor which uses the motion signal to calculate the physiological characteristic being measured. For pulse oximetry, a least squares or a ratio-of-ratios technique can be applied to the motion signal itself. This is made possible by selecting a site on the patient where variations in motion produce signals of two wavelengths which are sufficiently correlated. In particular, it has been determined that a sensor placed on a nail, in particular a thumbnail, exhibits the characteristics of having the red and infrared signals correlated when used for pulse oximetry, and the resulting signals correlate to arterial oxygen saturation.Type: GrantFiled: November 16, 2004Date of Patent: August 21, 2007Assignee: Nellcor Puritan Bennett IncorporatedInventors: Rodney Chin, Paul Mannheimer, Ross Flewelling
