Physiological Parameters

The purpose of this study is to use the OXYFLEX® device in real care conditions during the hospital management of a population of patients from various hospital services. These services include patients from the severe trauma pathway, intensive care, the polyvalent intensive care unit, and the operating room. The objective is to assess the reliability of the data collected by the OXYFLEX® biosensor compared to those obtained from standard monitoring used in these different services and conditions.

The population included in this study consists of tracheostomy patients admitted to the pulmonary department of Beijing Rehabilitation Hospital, undergoing decannulation rehabilitation treatment. After the patient is admitted, the research team evaluates whether they are suitable to enter the decannulation process. For enrolled patients, a 24-hour wearable device is worn upon admission to record physiological parameters. Patients, following clinical and rehabilitation treatment, can start using a "speaking valve" as soon as their condition permits. Within the first 24 hours prior to the initial use of the speaking valve, wearable devices may be utilized a second time to gather data. Patients successfully completed the decannulation process, tolerating the speaking valve for 4 hours (PEF/PCF ≥ 100liters/min).The wearable device was utilized to gather 24 hours physiological parameters for the third time within the 24 hours leading up to decannulation. Patients who underwent successful decannulation had physiological parameters collected for the forth time using wearable devices within 24 hours prior to discharge. This study preliminarily compares the differences in physiological parameters at four time points (within 24 hours of admission, within 24 hours prior to using a speaking valve, within 24 hours prior to decannulation and within 24 hours before discharge), predicts the physiological benefits of decannulation for patients, and advocates for the concept of "early decannulation." Decannulation criteria: If the patient can tolerate wearing the speaking valve continuously for 4 hours (gradually increasing the duration: 30 minutes, 1 hour, 2 hours, 4 hours), and if PEF/PCF ≥ 100 liters/min, planned removal of the tracheostomy tube can be considered. Criteria for successful decannulation: Patients who successfully completed the decannulation process and had their tubes removed, with no reinsertion of the tracheostomy tube or endotracheal intubation within 48 hours after decannulation.
