Detecting Post-surgical Respiratory Compromise and Prompting Patients to Self-rescue: An Early Feasibility Study
United States40 participantsStarted 2017-10-01
Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Patients who undergo surgical procedures associated with a post operative hospital stay of at least 24 hours.
. Patients with known or suspected obstructive sleep apnea (OSA). Known OSA will be defined as a sleep hypopnea study within the last 10 years that is consistent with OSA. Suspected OSA will be defined as a patient with a screening questionnaire (STOP-Bang) score of 5-8 (A score consistent with a high risk of OSA). The STOP-Bang questionnaire is a built in component of the anesthesia preopreative evaluation in EPIC.
. Patients who will undergo surgical procedures associated with significant post operative pain and require opioid analgesics to manage pain. Sample procedures include major extremity surgery, spine surgery, abdominal surgery, and chest surgery that require a post operative in patient hospital stay.
Exclusion criteria
. Patients who are discharged home on the day of surgery.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Oxygen saturation measured by pulse oximetry (SpO2)
Timeframe: Average and median SpO2 will be measured every 10 minutes for approximately the first 24 hours after surgery during the patient's stay
2
Breath promoting success rate
Timeframe: Change in respiratory rate from baseline to the period 10 seconds after the breath prompt every 10 minutes for approximately the first 24 hours after surgery during the patient's stay
