Prolonged Mechanical Ventilation

This study aims to evaluate the effects of powered lower-limb exoskeleton-assisted training on lower limb strength, respiratory parameters, 28-day ventilator-free days, and length of hospital stay in patients with prolonged mechanical ventilation admitted to a Respiratory Care Center. The goal is to provide clinical evidence for integrating rehabilitation and respiratory care in this patient population.

This prospective observational study evaluates the association between intraoperative mechanical power (MP) - a composite measure of the total energy delivered to the lungs during mechanical ventilation - and postoperative pulmonary complications (PPCs) and prolonged mechanical ventilation in adult patients undergoing elective coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB). Intraoperative ventilatory parameters including tidal volume, respiratory rate, airway pressures, and PEEP will be recorded and used to calculate MP and driving pressure (DP). No additional interventions will be applied beyond standard clinical care.

Patients with prolonged mechanical ventilation (PMV) frequently experience impaired ventilation distribution, respiratory muscle dysfunction, secretion retention, and delayed liberation from mechanical ventilation. Electrical impedance tomography (EIT) provides real-time bedside visualization of regional ventilation and enables individualized respiratory physiotherapy strategies. This multicenter randomized controlled trial aims to evaluate whether EIT-guided respiratory physiotherapy improves ventilator-free days at day 28 compared with conventional respiratory physiotherapy in adult patients with PMV. Respiratory physiotherapy consists of airway clearance, chest physiotherapy techniques, breathing pattern optimization, and therapeutic positioning. In the EIT-guided group, real-time EIT imaging is used to individualize physiotherapy strategies based on predefined ventilation distribution indicators, while the control group receives standardized physiotherapy according to institutional protocols without EIT guidance. Secondary outcomes include successful liberation from mechanical ventilation, diaphragm ultrasound parameters, EIT-derived ventilation distribution indices (exploratory mechanistic outcomes), ICU Mobility Scale, healthcare resource utilization, and safety outcomes.

The purpose of this study is to evaluate the effects of music therapy on anxiety symptoms in patients requiring prolonged mechanical ventilation (PMV). PMV patients, defined as those ventilated for more than 21 days, often experience intense psychological stress and anxiety due to long-term intubation and the ICU environment. High anxiety can lead to "patient-ventilator asynchrony," which delays the weaning process. In this study, 200 participants will be randomly assigned to either a control group receiving standard care or an experimental group receiving patient-directed music therapy. The music therapy intervention involves listening to selected music through noise-canceling headphones for 30 minutes, twice daily, over a 14-day period. The study will measure improvements in anxiety levels, pain, and sleep quality to determine if music therapy can help break the cycle of anxiety and facilitate recovery.

This study is based on the risk factors of previous studies to formulate a bundle treatment plan to prevent ventilator dependence in children, in order to reduce the proportion of ventilator dependence in children and provide a theoretical basis for reasonable intervention of children with mechanical ventilation. Participants will receive intensive rehabilitation, nutrition, and tracheotomy at different time periods. Researchers will compare the control group to see whether it can reduce the incidence of ventilator dependence

The main objective of the study is to determine whether a subnormal serum creatinine value upon admission to the Post-ICU Care Unit predicts the need for prolonged ventilatory support. A parallel objective of the study is to determine whether exogenous in-take of the dietary supplement creatine in patients with subnormal serum creatinine value is associated with a shortened duration of ventilatory support and improved patients outcome.

Prolonged mechanical ventilation (PMV) and weaning failure can lead to extended hospital stays, as well as increased morbidity and mortality during hospitalization. Therefore, PMV not only increases the economic burden on patients and their families, but also adds to the societal economic burden and consumes critical care medical resources. Inspiratory muscle training (IMT) is widely used by physical therapists in critically ill patients to improve respiratory function and enhance quality of life. IMT helps improve diaphragmatic function, and the improvement of diaphragmatic function in turn promotes better respiratory function, which is clinically significant for accelerating weaning. However, most studies on the effects of IMT on weaning success rates and the duration of mechanical ventilation have limitations such as small sample sizes, homogeneous patient populations, and short intervention periods. As a result, there is still no unified, high-quality evidence-based consensus. The purpose of this study is to further clarify the role of IMT in improving diaphragmatic function and increasing weaning success rates in patients with prolonged weaning, through clinical treatment and the collection and analysis of relevant data.

This project will conduct a series of analysis of physiological and clinical data on tracheostomy patients who receive prolonged mechanical ventilation, hoping to find out the different manifestations of patients through the investigation by a variety of physiologic measurements, so as to understand whether different types of patients phenotype to derive different clinical strategies for liberation of the mechanical ventilator.
