Abstract: Objective: To investigate the clinical practice status of the Clinical Practice Standards for Arterial Blood Gas Analysis published in 2017, and to provide reference for further standardizing clinical practice for arterial blood gas analysis in adults. Methods: From April 12 to May 31, 2022, a self-designed questionnaire was used to investigate the practice status of adult arterial blood gas analysis among medical staff from 134 medical institutions in China by convenience sampling. Results: A total of 500 valid questionnaires were collected, and 28.2% respondents preferred 2% chlorhexidine gluconate ethanol solution as skin disinfectant. In clinical arterial blood gas sampling, 90.4% of the preferred site were radial artery, and the needle entry angles were slightly different. Only 15.0% removed three times the dead space volume of mixture blood; 73.8% correctly mixed the specimens after blood collection; 76.2% could complete the test within 30 minutes. There were 8.6% of the respondents who suffered needle injuries due to arterial blood collection operation. Conclusion: There are differences in the disinfection methods of arterial blood gas analysis, puncture sites for blood collection, and needle entry angles among medical staff. The quality control of arterial blood gas sample collection, transportation, and preservation needs to be optimized. The training and examination related to arterial blood gas analysis are insufficient, and the awareness of occupational protection is weak. The success rate of arterial blood collection can be improved by strengthening the training of adult arterial blood gas analysis operation knowledge and skills, and the quality control of the collection process, to ensure the accuracy of test results.
