Abstract
A vital signs monitor comprising a first device capable of being disposed at a selected location on a patient to pass at least exhaled gases therethrough; a second device coupled to the first device to perform a plurality of resistive measurements of certain predetermined parameters of the exhaled gases and a plurality of optical absorption measurements of other predetermined parameters of the exhaled gases; and a third device coupled to the second device responsive to the plurality of resistive measurements and the plurality of optical absorption measurements to provide individual read outs of at least a value of carbon dioxide in the exhaled gases, a value of tidal volume of the exhaled gases and a value of a respiration rate of the patient.
Claims23
A vital signs monitor comprising:
- first means adopted to be disposed at a selected location on a patient to pass at least exhaled gases therethrough;
- second means coupled to said first means to perform a plurality of resistive measurements of certain predetermined parameters of said exhaled gases and a plurality of optical absorption measurements of other predetermined parameters of said exhaled gases;
- and
- third means coupled to said second means responsive to said plurality of resistive measurements and said plurality of optical absorption measurements to provide individual read outs of at least a value of carbon dioxide in said exhaled gases, a value of tidal volume of said exhaled gases and a value of a respiration rate of said patient.
