Abstract
Provided are systems and methods for minimally invasive arterial blood gas measurements. Blood samples are collected using capillary microstructures that minimize patient discomfort and collect samples in a manner such that the samples are not exposed to an environment outside of the sample collection portion. One or more characteristics of the blood sample are then calculated and used to derive one or more arterial blood gas measurements for the sample.
Claims15
A system for providing arterial blood gas measurements, comprising:
- a sample collection portion positioned in contact with a tissue of the patient such that a blood sample travels from the tissue of the patient into the sample collection portion without being exposed to an environment outside of the sample collection portion;
- one or more analysis portions in fluid communication with the sample collection portion, wherein each of the one or more analysis portions analyze one or more characteristics of the blood sample;
- and
- at least one processor configured to:
- receive the one or more characteristics of the blood sample, and
- calculate one or more arterial blood gas measurements using the one or more characteristics.
