Technical Feasibility Study of a Novel Wearable Capnograph (MARIE) in an Emergency Care Environment, Part 1

Sweden49 participantsStarted 2024-12-19

Plain-language summary

You have been assessed by paramedics as needing to go to the emergency department. During transport, the paramedics will monitor you by, for example, measuring your blood pressure and checking your pulse. In healthcare, we are constantly working to improve and optimize the degree of monitoring during ambulance transports and through this also be able to start adequate treatment earlier. In this case, we are working to understand whether exhaled carbon dioxide levels can be used to monitor important processes in the body during ambulance transport. Therefore, we offer you to participate in a project that deals with whether we can use a new equipment to measure and monitor exhaled carbon dioxide during the journey to hospital. This clinical trial is being conducted in Region Uppsala in collaboration with Oxlantic Medical AB. The main responsible and Sponsor for the trial is Oxlantic Medical AB. The research lead for the trial is Region Uppsala and Uppsala University. This clinical trial has been subject to ethical review and approved by the Ethics Review Authority.

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

Adequate values of ETCO2 and respiratory rate

Timeframe: During ambulance transport from the start of the transport to the arrival at the emergency department
