Objective: The objective of this study is to investigate the frequency, causes and solutions of the problem of 'vent aspirator not sucking' encountered during cardiopulmonary bypass (CPB) and to evaluate its relationship with professional experience, institutional environment and educational status. Materials and methods: A descriptive cross-sectional study was conducted through an online survey of 186 actively practicing perfusionists across Turkey. A 17-item structured questionnaire was used to collect data on demographics, vent usage habits, problem frequency, perceived causes, interventions, and training background. Data were analyzed using descriptive statistics, chi-square tests, and multivariate logistic regression. Results: Approximately 65% of participants reported experiencing the vent problem occasionally or frequently, with the rewarming phase being the most common stage of occurrence (45.7%). The most frequently cited causes included incorrect cannula positioning (72.6%) and vacuum system issues (59.1%). Less experienced perfusionists and those working in private hospitals or high-volume centers reported significantly more problems. Receiving specific training on vent management reduced the risk by 45% (OR = 0.55, p = 0.035), yet 58.1% of perfusionists indicated insufficient training. Moreover, only 18.3% reported having standard protocols in their institutions. Conclusion: The "vent aspirator not sucking" issue is a widespread and multifactorial technical problem during CPB, significantly affected by experience, institutional factors, and training. Addressing this challenge requires the development of standardized procedures, structured education programs, and increased awareness of alternative venting strategies to improve patient safety and surgical outcomes.
