through the mouth with symptoms such as dry mouth and thirst. These symptoms can lead to

sympathetic nerve exciting, which aggravates anxiety and irritability [12] . During the non-analgesic

and sedative gastroscopy, the subjects adopted the breathing mode of nasal breathing, which could
prevent the exhaled gas from flowing through the glossopharyngeal plane and oral airway, thereby

avoided related symptoms such as dry mouth and thirst. It can also avoid sympathetic nerve
stimulation and exciting [13] , in order to reduce the subject's anxiety and irritability during non-

analgesic and sedated gastroscopy to a certain extent. Therefore, in the non-analgesic and sedative

gastroscopy, using the breathing mode of nasal breathing, compared with the breathing mode of

nasal inspiration and oral expiration, the subjects have less discomfort symptoms, feel less pain, and

better tolerance.

In this study, it was found that all the subjects in the nasal breathing group used the breathing mode

of nasal inhalation and nasal exhalation had completed the examination. While in the nasal

inspiration and oral expiration group, there was one subject who interrupted the examination and

failed to complete the whole process. The results of the study showed that the examination

completion rate of the nasal breathing group was greater than that of the nasal inspiration and oral

expiration group, however, the difference between the two groups was not statistically significant.
The reason for the analysis may be that when the subject adopts the nasal inspiration and oral

expiration mode, in the expiration stage, the air flow in the larynx caused by the exhalation airflow
is disordered, which aggravates the discomfort of the subject, and thus makes the subject unable to

tolerate and continue to complete the examination. Thereby terminating the inspection. The reason

may also serve as related to the individual differences of the subjects. The subjects have poor

tolerance for non-analgesic and sedative gastroscopy, resulting in their inability to tolerate and insist

on cooperating to complete the examination operation. The exact cause remains to be further

confirmed by large sample studies.

Through the study, it was found that the mean arterial pressure and heart rate value of the two groups

of subjects increased significantly when the gastroscope passed through the gastroesophageal

junction. While mean arterial pressure and heart rate values gradually return to the state before the

examination in the end, indicating that the effects of nasal breathing mode and nasal inspiration and

oral expiration mode on the subject's hemodynamics are basically the same. After the examination,

the subject's hemodynamics can be restored to the state before the examination. The blood oxygen
