About this study
Official title: Pilot Clinical Evaluation of the RHEA Vital Sign Vigilance System in Hospital Patients
This study comparing both of the investigational device and reference device to gold standard Patient Monitor of the accuracy of heart rate and respiratory rate monitoring. The primary variables for the analysis of heart rate (HR) and respiratory rate (RR) are each the overall mean root mean square difference (RMSD). Results of the investigational device and reference device compared with the patient monitor are evaluated to see if there are equivalent. Motion and bed exit accuracy will be evaluated by comparing with the manual observation.
Read the detailed description
The testing will be conducted in three periods. In the Accuracy Tests (periods
1 and 2), one of the contact-free devices will be used to monitor the HR and RR, while being compared with the Patient Monitor. The RHEA investigational device and reference device will be used to monitor the same subject at different times, as the sensors of the two devices are placed at a similar location of the bed. HR and RR will be recorded for all three devices.
The primary hypotheses for HR, are as follows:
Adults HO: μ = 3.25 vs. HA: μ < 3.25, Children HO: μ = 3.5 vs. HA: μ < 3.5,
The primary hypotheses for RR, are as follows:
Adults HO: μ = 2.25 vs. HA: μ < 2.25, Children HO: μ = 2.5 vs. HA: μ < 2.5, where μ represents the population mean HR or RR. If the upper bound of the confidence interval is less than the hypothesized value, the corresponding null hypothesis will be rejected. Comparison of the performance of the two contact-free devices will be performed on the recorded results via statistical analysis.
The hypothesis here is that the two devices have equivalent performance. The third test will assess the ability of the RHEA device to accurately detect motion on or exit from the bed, as compared to the manual observation. Motion and no motion accuracy will each be calculated along with their respective two-sided 95% confidence intervals.

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?
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?
RMSD of Investigational Device's Heart Rate and Gold Standard Device's heart rate (time frame: 30 days). The study lists 2 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 16 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
