Abstract
The objectives of this research and development study were to: 1) Investigate the problems and needs related to the care of patients undergoing ventilator weaning; 2) Develop a ventilator weaning model; and 3) Evaluate the effectiveness of the developed ventilator weaning model.
The sample consisted of 25 registered nurses and mechanically ventilated patients, including 40 patients in the experimental group and 40 patients in the control group, selected through purposive sampling. The research instruments included: 1) A Ventilator weaning assessment form, 2) A Ventilator weaning process record form, 3) A Knowledge test, and 4) A Satisfaction questionnaire. The content validity index (CVI) of the research instruments was 0.86. Data were analyzed using descriptive statistics, including frequencies, percentages, means, and standard deviations, as well as the Paired t-test, Independent t-test, and the Mann–Whitney U test. The results revealed that the developed ventilator weaning model was based on the A-B-C-D-E-F assessment pattern. It also consisted of three phases: readiness assessment before ventilator weaning, implementation of the weaning process, and readiness assessment before extubation. The model incorporated clear weaning criteria and standardized nursing practice guidelines. After implementation of the model, patients in the experimental group demonstrated a significantly higher ventilator weaning success rate compared with the control group (p < .05). Nurses achieved a good level of knowledge regarding ventilator weaning ( = 18.04, S.D. = 1.06), with a statistically significant improvement (p < .01). Nurse satisfaction with the model was at a very high level (
= 4.57, S.D. = 0.57). In conclusion, the developed ventilator weaning model was effective in improving both patient and nursing outcomes. The model can be effectively implemented in surgical intensive care units to enhance nursing quality and patient safety.
