THERAPY SYSTEM WITH A PATIENT INTERFACE FOR OBTAINING A VITAL STATE OF A PATIENT
First Claim
1. A therapy system comprising:
- a patient interface for delivering a flow of breathable gas to a patient, wherein the patient interface comprises a detection unit for detecting reflected light from a skin area of the patient;
a processing unit for processing the image signal; and
an evaluation unit for deriving information on a vital state of the patient based on an evaluation of a development of the image signal over time;
wherein the detection unit is configured to generate an image signal from the detected light and in that the processing unit is configured to identify a blood vessel of the patient within the skin area and to determine a size measure for the blood vessel, and wherein the evaluation is configured to evaluate a development of the determined size measure over time to derive information on the vital state of the patient.
