Trial summary

The aim of the trial is to prove that the Reassure10.5 GHz sensor is equivalent in performance to the SomnoScreen Plus RC in indicating the breathing rate of adult subjects over a number of hours when the subjects are lying still or in bed asleep Read more about this study

About this study

Official title: A Comparison of the Non-contact Reassure Device Measurement Accuracy of Respiration Rate With SOMNOScreen, When Measured on a Continuous Basis Whilst the Subjects Are Asleep

The aim of the trial is to prove that the Reassure10.5 GHz sensor is equivalent in performance to the SomnoScreen Plus RC in indicating the breathing rate of adult subjects over a number of hours when the subjects are lying still or in bed asleep

Read the detailed description

Each recording comprised at least 2 hours duration. The subject was lying on a bed, wearing the SomnoScreen and with the Reassure on a bed-side table in the recommended position: at arm's length, pointing at the subject's upper torso.

The subject was asked to lie in set positions on the bed for 20 minutes at a time. The data was recorded continuously for the duration of the trial and so encompassed the acts of turning from one position to another and any minor movement made by the subject. If the subject fell asleep during the trial, they were only woken when it came time for the next position change.

What is being measured

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

  1. Respiration Rate Comparability

    The respiration rate measured contemporaneously by the Reassure and the reference device, SomnoScreen, are compared on a second-by-second basis, over the whole recording duration. The difference between the two respiration rate measurements (the delta) for all 20 subjects' recordings are plotted on a normal distribution chart, giving 130,000 data points. The distribution chart reveals the mean difference between the two devices' measurements and the Standard Deviation (SD). The measure of success is if the 95% (ie 2SD) of the difference in the respiration rate indicated by the two devices (the delta) is less than 5 breaths per minute. This measure is derived from the peer review paper by Lim et al, cited in the References section

    Measured: 2 hour recording

Questions about this trial

What is this clinical trial studying?

An observational study of Accuracy of Respiration Rate Measurement, run by ResMed.

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 1 inclusion and 1 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 2 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 2 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Respiration Rate Comparability (time frame: 2 hour recording). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02740478, which also lists 1 linked publication.

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 2 Apr 2021.
