1. A method, comprising:
- using a processor;
receiving a signal from a photoacoustic spectroscopy sensor, wherein the signal from which a microcirculatory parameter of a patient may be determined;
determining the micro circulatory parameter based at least in part on the signal; and
determining whether the patient has shock and/or sepsis based at least in part on the microcirculatory parameter.

Abstract
According to various embodiments, a medical system and method for determining a microcirculation parameter of a patient may include a photoacoustic sensor. Specifically, a signal from a photoacoustic sensor may be used to determine if a patient is likely to have sepsis or shock. Although sepsis and shock present similarly with regard to many patient parameters, they may be differentiated by characteristic microcirculation changes.
