Example 2
The digital auscultation detection method for respiratory gas provided by the embodiment of the invention is based on the digital auscultation detection device for respiratory gas of the embodiment 1, as shown in fig. 4, and the detection method comprises the following steps:

In embodiments of the invention, the ketone bodies comprise: acetone, beta-hydroxybutyric acid and acetoacetate, in the case of the massive decomposition of fat, are present in the blood and urine in a significantly increased amount. Ketone bodies can be used as an alternative energy source for neurons and other cells that are unable to directly metabolize fatty acids. Because of its volatility, acetone enters the trachea through the alveolar gas exchange when blood passes through the lung, and is then discharged from the body. Ketone bodies are produced when the body is forced to use stored fat as the primary source of energy. There is a close relationship between diabetes and ketone bodies, as the presence of ketone bodies is an indication that insulin is unable to normally transport glucose to cells.
In the present example, exhaled nitric oxide assay is a commonly used detection means in respiratory medicine for detecting an indicator of chronic inflammation of the airways. Through the inspection of the exhaled nitric oxide, the condition of allergy of the pulmonary bronchus to the outside is known, the control condition of chronic inflammation of the airway is reflected, and a clinician is guided whether to adjust the medicine for treating allergic cough and allergic asthma.
Thus, in embodiments of the present invention, it is desirable to analyze nitric oxide and acetone concentrations in respiratory gases.

In an embodiment of the present invention, the odor determination rule includes: when the concentration of nitric oxide, and/or acetone gas in the respiratory gas exceeds a first preset threshold. When the concentration of nitric oxide and/or acetone in the respiratory gas is lower than a second preset threshold value. The values of the first preset threshold and the second preset threshold are not limited herein, and in practical application, the response is selected according to the actual situation.
In one embodiment, the odor determination rules are shown in the following table:
wherein a1, a2 and a3 are respectively lower threshold values of nitric oxide concentration in the respiratory gas under three inflammation conditions, b1, b2 and b3 are respectively upper threshold values of nitric oxide concentration in the respiratory gas under three inflammation conditions, c1 is an upper threshold value of acetone concentration in the respiratory gas in a low fat metabolism state and a lower threshold value of acetone concentration in a rapid fat metabolism state, and d1 is a lower threshold value of acetone concentration in the respiratory gas in a rapid fat metabolism state and an upper threshold value of acetone concentration in the respiratory gas in a high speed fat metabolism state.
In another embodiment, as shown in fig. 5, the working flow of the digital auscultation detection device for respiratory gas is as follows: firstly, the respiratory gas of a human body is collected, then the concentration of acetone and nitric oxide gas in the respiratory gas is obtained by using a gas detection module, the analysis result of respiratory gas related diseases is obtained by a health state analysis module, and the health state of the human body at the current stage is judged. In addition, the breath ketone body detection can also provide the ketone body change condition for the ketogenic eater, and further reasonably adjust the diet structure.
Wherein, ketogenic diet: generally refers to a diet of very low carbohydrate content, moderate protein content, high fat content, intended to induce the production of ketone bodies. A "classical" ketogenic diet generally refers to a very low carbohydrate diet under medical supervision with a ratio of dietary fat to dietary protein and carbohydrate of 4: 1 or 3: 1. the ketogenic diet can obviously reduce weight, reduce blood sugar, increase high density lipoprotein cholesterol, reduce triglyceride, reduce blood pressure and the like under the condition of not limiting fat (even saturated fat) and total heat. Some scholars believe that ketogenic diets are promising as a first-line non-drug treatment for obese and diabetic patients, or may become an ideal alternative to weight loss drugs, metabolic surgery.
