1. 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, whereby providing the at least one output further comprises defining at least one of a visual target and a visual threshold for the dynamic respiratory arterial pressure wave and providing the at least one of the visual target and the visual threshold to at least one of a clinician and a user.
