Abstract
The present invention specifies a method and system for assessing the dynamic respiratory arterial pressure wave using plethysmographic sensing techniques. The dynamic respiratory arterial pressure wave is measured and plotted for purposes of diagnosis and or remedial biofeedback.
Claims12
A method for assessing a dynamic respiratory arterial pressure wave, comprising:
- detecting the dynamic respiratory arterial pressure wave as a function of changing blood volume using a plethysmographic device;
- assessing at least one characteristic of the dynamic respiratory arterial pressure wave;
- and
- providing at least one output for diagnostic purposes, wherein the at least one output represents the assessed at least one characteristic of the dynamic respiratory arterial pressure wave, and
- whereby providing the at least one output further comprises specifying at least one of an amplitude change, a frequency change, and a phase change for the dynamic respiratory arterial pressure wave.

A system for assessing a dynamic respiratory arterial pressure wave, comprising:
- a plethysmographic device adapted to sense changing blood volume;
- and
- a computing device adapted to:
- detect the dynamic respiratory arterial pressure wave as a function of the changing blood volume;
- assess at least one characteristic of the dynamic respiratory arterial pressure wave;
