Abstract: A medical breath component analyzer which maintains a data-base profile of a patient over time. The apparatus may be used chronically by a patient so that a baseline status for that patient may be determined. Acute variations from the baseline are identified as clinically significant. The acquired data can be reported to the patient using the device at home and transmitted electronically to a physician or health care provider. The method and apparatus helps a patient modify health related behaviors, particularly weight loss for diabetic patients. A breath component and information on the psychological or emotional state of the patient are correlated, and information is provided to the patient based on the correlation between the breath component and the patient's emotional state. Other physiologic parameter may also be measured, such as a blood component, temperature, cardiovascular condition or pulse rate, a urine component, a physical activity sensor, weight, or body fat composition sensor.

Abstract: A medical breath component analyzer which maintains a data-base profile of a patient over time. The apparatus may be used chronically by a patient so that a baseline status for that patient may be determined. Acute variations from the baseline are identified as clinically significant. The acquired data can be reported to the patient using the device at home and transmitted electronically to a physician or health care provider. Multiple tests may be provided, ranging from quantitative tests to qualitative tests to quantitative approximations using qualitative devices. A set of tests is selected for a particular patient, and may be customized to the patient's condition. One of the tests may include passing multiple laser beams of differing wavelengths through a breath sample and using pattern recognition to correlate from spectral analysis of all the laser beams.
