Trial summary

Pressure Support Ventilation use Expiratory triggering sensitivity (Esense) to transfer inspiration to expiration, the value of Esense is fixed. That may lead to asynchrony between humans and ventilators, making people uncomfortable and prolonging weaning time. Read more about this study

About this study

Official title: Automatic Adjustmen of Inspiratory Triger and Cycling-off Based on Waveform Improved Patient-ventilator Interation During Pressure Support Ventilation

Pressure Support Ventilation use Expiratory triggering sensitivity (Esense) to transfer inspiration to expiration, the value of Esense is fixed. That may lead to asynchrony between humans and ventilators, making people uncomfortable and prolonging weaning time. Furthermore,trigger delay or inffective trigger happens frequently during insppiratory triggering. The ventilators have a compunter drived funcation of automatic adjustmen of inspiratory triger and cycling-off based on waveform, IntelliCycleTM 2.0. It will make the transforming more synchrony with humans. The objectibe of the present study is to detect the effect of automatic adjustmen of inspiratory triger and cycling-off based on waveform on patient-ventilator interation.

Read the detailed description

This is a physiological cross-over study. Enrolled patient with different baseline respiratory mechanics, for example ARDS patients with low compliance, COPD patient with high airway resistance and postoperative patients with almost normal compliance and airway resistance. Patients are ventilated with PSV+ Automatic adjustmen of inspiratory triger and cycling-off based on waveform, PSV with fixed inspiratory and expiratory and NAVA in two different levels of support. The demographic characteristics, diagnosis, formerly medical history, Ventilator indications, Ventilator data, other respiratory treatments, patient-ventilator interation, work of breathing, Eadi, will be recorded.

    Measured: 20 minutes

Secondary outcomes (4)
  1. Patient Respiratory Patterns

    Patient Respiratory Patterns during Pressure Support Ventilation

    Measured: 20 minutes

  2. gas exchange

    Patient gas exchange during Pressure Support Ventilation

    Measured: 20 minutes

  3. work of breathing

    work of triggering and respiratory in different arms

    Measured: 20 minutes

  4. other patient-ventilator synchrony parameters

    trigger and cycle-off asynchrony, Ineffective efforts, double triggering, auto-triggering, premature cycling and late cycling

    Measured: 20minutes

Questions about this trial

What is this clinical trial studying?

A study testing automatic adjustmen of inspiratory triger and cycling-off based on waveform and PSV with fixed Esence in people with Automatic Adjustmen of Inspiratory Triger and Cycling-off, run by Southeast University, China 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 8 inclusion and 7 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 28 Jul 2021. 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. Some participants in this study may receive a placebo. 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?

Asynchrony Index (time frame: 20 minutes). 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 28 Jul 2021.
