SYSTEM AND METHOD FOR UTILIZING EXHALED BREATH FOR MONITORING INFLAMMATORY STATES |
摘要 |
A system for monitoring an exhaled breath of a subject is described. A breath collector can be configured to receive exhaled breath from a subject. One or more sensors can be configured to output a concentration of a first gas compound in the received exhaled breath, and to output a concentration of a second gas compound in the received exhaled breath. The second gas compound is used to normalize the concentration of the first gas based on different physiological states of the subject. A processor operably coupled to the one or more sensors is configured to calculate a ratio of the first gas compound to the second gas compound based on the determined concentrations, and to determine a normalized concentration of the first gas compound. This ratio may be monitored to evaluate an inflammatory state of the subject. |

1. A method comprising:
collecting a sample of exhaled breath from a subject; determining a concentration of a first gas compound in the collected sample; determining a concentration of a second gas compound in the collected sample; calculating a ratio of the concentration of the first gas compound to the concentration of the second gas compound to determine a normalized concentration of the first gas compound; and diagnosing a disease state based on the determined concentration of the first gas. |
