Analysis of influencing factors and acceptance on manual hyperinflation in patients with open sputum suction after tracheotomy

Objective To investigate the acceptance and influencing factors of manual hyperinflation (MIH) in patients with open sputum suction after tracheotomy, so as to provide reference for improving the acceptance of MIH for patients. Methods By convenience sampling, 140 patients with tracheotomy on open suction in Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine from October 2016 to September 2018 were selected as participants in the study and the Self-Designed Questionnaire was used to study the acceptance towards MIH of the patients. Univariate analysis and Logistics regression analysis were conducted to analyze the influencing factors of the acceptance of patients on MIH. A total of 140 questionnaires were distributed, and 134 valid ones were collected. Results Univariate analysis showed that there were statistical difference in age, gender, family support, duration of tracheotomy, whether the medical staff had explained the relevant knowledge of MIH, and whether the patients had experienced MIH on patients' acceptance of MIH (P<0.05) . The above 6 statistically significant factors were analyzed by multivariate Logistic regression and the results showed that age, gender, duration of tracheotomy, whether the patients had experienced MIH before were the influencing factors of the patients' acceptance on MIH (P<0.05) . Conclusions Age, gender, duration of tracheotomy, whether or not the patents have experienced MIH are independent impact factors for the patients' acceptance of MIH and the above factors can be the cut-in points of explanation and education in the process of MIH, so as to improve the patients' acceptance of MIH and promote recovery.
