# Non-Contact Respiratory Rate Monitoring

**Official Title:** Evaluation of Non-Contact Respiratory Rate Monitor in Post-Surgical Subjects

**NCT ID:** [NCT04005911](https://clinicaltrials.gov/study/NCT04005911)

## Key Facts

- **Status:** UNKNOWN
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 100
- **Lead Sponsor:** University of Virginia
- **Conditions:** Hypoxia
- **Start Date:** 2019-04-18
- **Completion Date:** 2019-09
- **CT.gov Last Update:** 2019-07-18

## Brief Summary

The purpose of this study is to compare thermographic estimates of respiratory rate to manual counting (visual inspection) and thoracic impedance-based methods. Thermographic methods rely on detection of temperature changes in the nose and mouth that occur as room temperature air passes through the nose and mouth during ventilation, and may offer a non-invasive means of measuring respiratory rate without requiring any patient contact.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL

```
Inclusion Criteria:

* Underwent surgery at the University of Virginia
* Able to provide verbal consent to participate in the study

Exclusion Criteria:

* Unable to provide verbal consent to participate in the study
* Youth
* Prisoners
```

## Arms

- **Post-Surgical** — Patients who underwent surgery and were admitted to the PACU

## Interventions

- **Themography** (DEVICE) — Using a FLIR camera, a thermographic recording will be taken of the patient while breathing. Simultaneously, the research investigator will record the thoracic impedance-based respiratory rate as well as manually count respirations in one minute.

## Primary Outcomes

- **Agreement between manually calculated respiratory rate and thermographic respiratory rate** _(time frame: 5 minutes)_ — Agreement between manually calculated respiratory rate and thermographic respiratory rate using the Limits of Agreement approach
