Patent ID: 7181264

Claim:
A method of using a SCBA mask having emitter and detector sensors for obtaining non-invasive pulsatile physiologic parameters and non-pulsatile physiological parameters comprising the steps of: (a) determining optimal distance between said emitters and said detectors; (b) placing and securing said mask on an individual's face and reducing incidences of motion artifact and orienting said emitter and detector sensors perpendicular to said individual's forehead; (c) supplying a light array from said emitter to said individual's forehead and capillary bed and bounding said array off said individual's bone' (d) detecting and transmitting said light to a remote processor; (e) obtaining said physiologic parameters pertaining to said pulsatile parameters and said non-pulsatile parameters; (f) correlating said physiologic parameters to optimal monitoring and accuracy of individuals using said SCBA mask in extreme conditions; (g) using direct current signals and obtaining constant and variable non-pulsatile readings; (h) analyzing said non-pulsatile readings and obtaining said non-pulsatile physiologic parameters; (i) using alternating current signals and obtaining pulsatile readings; and (j) analyzing said pulsatile readings and obtaining said pulsatile physiologic parameters.
