About this study

Official title: Predicting the Clinical Advantages of Speaking Valves Through Wearable Devices:A Prospective Cohort Study

The population included in this study consists of tracheostomy patients admitted to the pulmonary department of Beijing Rehabilitation Hospital, undergoing decannulation rehabilitation treatment. Once patient conditions stabilized, they were all transitioned to the decannulation process established by our department in 2018, which utilizes a speaking valve instead of capping.The initial duration for the patient to wear the speaking valve is 30 minutes.The monitoring period for wearable devices is from 1 hour before the initial use of the speaking valve to 1 hour after its removal.Monitored for a total of 2 hours and 30 minutes.Explore the clinical benefits of the speaking valve by comparing the changes in patients' physiological parameters and clinical index metrics before and after using the speaking valve.

Criteria for the successful use of the speaking valve for 30 minutes:

  1. Breathing is steady at rest: no apparent dyspnea, chest tightness, or orthopnea, etc.
  2. Heart rate, blood pressure, and SpO₂ are all stable overall.SpO₂ reduction from baseline < 5%.
  3. No frequent need for emergency sputum suction or indications of sputum blockage while wearing it.

    Once patient conditions stabilized, they were all transitioned to the decannulation process established by our department in 2018, which utilizes a speaking valve instead of capping.The initial duration for the patient to wear the speaking valve is 30 minutes.If the patient can tolerate wearing the speaking valve for 30 minutes, they fulfill the inclusion criteria.The monitoring period for wearable devices is from 1 hour before the initial use of the speaking valve to 1 hour after its removal.Monitored for a total of 2 hours and 30 minutes.

    Physiological parameters recorded prior to wearing the speaking valve served as the baseline.Compare the physiological parameters while wearing the speaking valve and after its removal to investigate the clinical benefits that the speaking valve can provide.To promote the application of speaking valves in future clinical work more effectively

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. degree of change in oxygen saturation(%)

    Previous studies have been concerned that speaking valve placement increases upper airway resistance, thereby inducing dyspnea and hypoxemia in patients. Therefore, we used continuous wearable physiological monitoring devices to observe changes in oxygen saturation before, during, and after the training.

    Measured: Using wearable biosensors, high-resolution physiological data were continuously collected during three phases: baseline (30 minutes), speaking valve placement period (30 minutes), and recovery period (30 minutes after speaking valve removal).

  2. Temporal rate of change of asymmetric cardiovascular responses and delayed autonomic recovery(percentage change from baseline)

    The rate of change (percentage per minute) in asymmetric cardiovascular responses (e.g., heart rate variability indices) and delayed autonomic recovery will be calculated. Physiological data (heart rate, HRV metrics) are continuously collected before, during, and after speaking valve placement. The primary reported value is the slope of change over time, expressed as a percentage relative to baseline, aggregated across all participants using mixed-effects modeling to produce a single mean rate of change

    Measured: 30 minutes before speaking valve placement, throughout the entire training session (i.e., during valve wear), and 30 minutes after the training session

  3. Rate of respiratory phase variation during training(percentage change in phase duration)

    The rate of change in respiratory phase variation (e.g., changes in inspiratory/expiratory time proportion) during speaking valve training. Respiratory parameters are continuously recorded. The outcome is the calculated rate of change (percentage per minute) from baseline to the active training period and to the recovery period. A single aggregated value (mean slope) will be derived from all participants using linear mixed models.

    Measured: 30 minutes before speaking valve placement, throughout the entire training session (i.e., during valve wear), and 30 minutes after the training session

Questions about this trial

What is this clinical trial studying?

A study testing Tracheostomy patients who are able to tolerate wearing a speaking valve for 30 minutes in people with Physiological Parameter and Wearable Devices, run by Bin Zhang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

degree of change in oxygen saturation(%) (time frame: Using wearable biosensors, high-resolution physiological data were continuously collected during three phases: baseline (30 minutes), speaking valve placement period (30 minutes), and recovery period (30 minutes after speaking valve removal).). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2026.
