Health monitoring of CO concentration in exhaled breath: 2/3 of the exhaled breath of the subject was collected in a plastic balloon and measured with a CO-II carbon monoxide meter. Electrocardiogram examination: ECG examination was performed by a full-time staff using the ECG-6511 electrocardiograph. The diagnosis is collectively analyzed by an experienced physician. 2 and t tests were performed using SPSS statistical software.
The air CO condition of the public canteen kitchen was over the standard rate of 71.15%, and the maximum exceeding the standard was 19.5 times. Health Status Exhaled CO concentration Because smoking is an important factor affecting the concentration of exhaled CO, we analyzed whether the smoking CO concentration in the observation group and the control group was significantly higher than that in the non-smoker group. The difference was statistically significant. (P<0.05). In the smokers, the exhaled CO concentration in the observation group was higher than that in the control group, and in the non-smokers, the exhaled CO concentration in the observation group was higher than that in the control group, and the difference was statistically significant.

The difference between the two groups was statistically significant (P <0.05). According to the analysis of abnormal changes of electrocardiogram, the abnormal rate of abnormal changes in the observation group were higher than those in the control group, but only the QRS wave was blunt or there was significant difference between the two groups (P<0.05).

Discussion This survey shows that CO in the kitchen air is the main pollutant in the public canteen, mainly from incomplete combustion of fuel and cooking fumes. Therefore, it is recommended that relevant departments should take practical measures to change the fuel structure, improve the combustion mode, and increase the ventilation of the kitchen to reduce the CO concentration in the kitchen air.
The exhaled CO increased with the increase of COHb in the blood, and the degree of increase was highly positively correlated<2>. At the same time, the content of COHb in human blood was a specific and sensitive index for evaluating CO in the environment<3>. The exhaled CO concentration was significantly increased <4>, and the results of this paper confirmed this. The CO concentration in the smokers' observation group was significantly higher than that in the control group. The non-smokers also observed that the exhaled CO concentration in the observation group was significantly higher than that in the control group, which fully indicated that the CO concentration of the exhaled gas of the cook was related to the CO pollution level in the kitchen air. Electrocardiogram results showed that long-term exposure to low concentrations of CO can cause chronic damage to the heart. The QRS of the observation group was significantly blunt or notch significantly higher than the control group (P<0.05), suggesting that CO mainly affects cardiac conduction in the heart. Thus appearing as a blunt or notched on the QRS waveform. Gao Yuchun <5> reported that CO at a low concentration (COHb less than 0.5%) can aggravate the condition of patients with coronary heart disease, and this low level of COHb is generally considered not to cause obvious clinical symptoms, when the CO concentration is high (COHb 20% to 30%) can induce myocardial infarction and increase mortality. Therefore, the relevant departments should take appropriate measures to control the concentration of CO in the kitchen air. The chopper should regularly perform an electrocardiogram examination to detect chronic damage to the myocardium caused by long-term exposure to low concentrations of CO.
