A Pilot Study Investigating the Detection of Episodes of Severe Patient-Ventilator Asynchrony

An observational study in Respiratory Failure, sponsored by Autonomous Healthcare, Inc.. Status unknown at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-05-31.

  1. The study's title name Patient-Ventilator Asynchrony, a narrower term within Respiratory Insufficiency.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

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 researchers measure

Primary outcomes

  1. 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.

    Time frame: Up to 4 weeks

Secondary outcomes

  1. 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

    Time frame: Up to 4 weeks

  2. 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

    Time frame: Up to 4 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 31, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
