Trial Summary

What is the purpose of this trial?

This study will explore the feasibility of an idea to use standard, FDA-approved patient monitors to detect ventilatory depression and then play a recorded nurse's voice to prompt patients by name to breathe. The voice prompt will occur in addition to when the traditional alarms are sounded by the monitors. The study device consists of commercially available physiologic monitors, a speaker, and a laptop computer. The physiologic monitors include a pulse oximeter with a motion sensor, capnometer, and nasal airway pressure sensor (built into a nasal cannula). Nasal pressure is a commonly used clinical monitor for sleep apnea detection during polysomnography testing in sleep labs.

Eligibility Criteria

This trial is for patients who will stay in the hospital at least 24 hours after surgery, including those with known or high-risk obstructive sleep apnea (OSA), and nurses caring for these patients. It's not for day-surgery patients, pregnant women, prisoners, or those unable to consent.

Inclusion Criteria

I had surgery that required me to stay in the hospital for at least one day.

I have or might have sleep apnea based on a test or high STOP-Bang score.
