5. Conclusions
Results of this study indicated that by considering the benefits of decreasing mechanical ventilation duration and the importance of preparing the required conditions for the patients’ earlier weaning from mechanical ventilator; safe and complementary therapies such as sound therapy can be used besides other therapies for earlier preparation of the patients for this process. It is hoped to decrease earlier weaning of the patients and speed up this process through getting help from complementary therapies. The study was along with limited number of the samples; it is recommended to conduct a study with more sample size.
