Abstract
Embodiments of the present invention relate to a method for analyzing pulse data. In one embodiment, the method comprises receiving a signal containing data representing a plurality of pulses, the signal generated in response to detecting light scattered from blood perfused tissue. Further, one embodiment includes performing a pulse identification or qualification algorithm on at least a portion of the data, the pulse identification or qualification algorithm comprising at least one constant, and modifying the at least one constant based on results obtained from performing the pulse identification or qualification algorithm, wherein the results indicate that a designated number of rejected pulses has been reached.
Claims31
A method for analyzing pulse data, comprising:
- receiving a signal at a pulse oximeter, the signal containing data representing a plurality of pulses, and the signal generated in response to detecting light scattered from blood perfused tissue;
- performing a pulse qualification algorithm on at least a portion of the data using a processor of the pulse oximeter, the pulse qualification algorithm rejecting non-qualified pulses, the pulse qualification algorithm comprising at least one constant;
- and
- modifying the at least one constant using the processor based on results obtained from performing the pulse qualification algorithm, wherein the results indicate that a designated number of rejected pulses has been reached.
A system for analyzing pulse data, comprising:
- a signal generator configured to generate a signal in response to detecting light scattered from tissue, the signal containing data representing a plurality of pulses;
- a filter configured to run a pulse qualification algorithm on at least a portion of the data, the pulse qualification algorithm configured to reject non-qualified pulses, the pulse qualification algorithm comprising at least one constant;
- and
- a subsystem configure to modify the at least one constant based on results obtained from performing the pulse qualification algorithm, wherein the results indicate that a designated number of rejected pulses has been reached.
