About this study
Official title: A Pilot Study Investigating the Detection of Episodes of Significant Patient-Ventilator Asynchrony in Mechanically Ventilated Patients
The goal of this study is to determine what percent of severe patient-ventilator asynchrony is detected in mechanically ventilated patients in the adult ICU and to determine delays in detecting those asynchronies by the staff that were correctly identified, and whether asynchrony status recorded during intermittent assessments by respiratory therapists is representative of periods in between such assessments.
Read the detailed description
This is a prospective observational study. All decisions about ventilator settings, mode of ventilation, and sedative doses are determined by the critical care team attending to the patient. Patients will be enrolled within 6 hours after intubation and will be studied continuously until extubation. Patients will be monitored for asynchrony using Syncron-E tablets provided by Autonomous Healthcare. However, clinical staff will be blinded to the results of the tablet, and hence, there will be no change to clinical care.
Asynchrony index (which captures the fraction of breaths with asynchrony) will be calculated every minute by the Syncron-E tablet. The assessment of respiratory therapists at the time of ventilator checks will also be recorded including the following information: i) entering/exiting the room , ii) existence of a severe asynchrony episode based on the respiratory therapist's assessment and its type. Clinical staff will record the start of any severe asynchrony episode that they detect. Data related to the administrations of sedatives and anesthetics as well as major interventions (excluding any PHI) will also be recorded.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of asynchrony events per minute and the asynchrony index
The endpoints will be calculated starting from the end of each ventilator check (when the respiratory therapist is leaving the room) and cover the time from that time point until 5-minutes prior to the next ventilator check event. The endpoints will also be separately calculated for the 5-minute period immediately preceding the next ventilator check.
Measured: Up to 4 weeks
Secondary outcomes (2)
Time difference between when the Syncron-E tablet detects the start of severe asynchrony episodes and when the clinician-detects the start of severe asynchrony episodes
Measured: Up to 4 weeks
Number of Syncron-E tablet-detected severe asynchrony episodes that went undetected by clinicians and the number of clinician-detected severe asynchrony episodes undetected by Syncron-E tablet
Measured: Up to 4 weeks

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 3 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 31 May 2022. 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 United States. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of asynchrony events per minute and the asynchrony index (time frame: Up to 4 weeks). 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 31 May 2022; AzTrials last refreshed its copy on 7 Nov 2026.
