Testing a new wearable device to monitor carbon dioxide levels in ambulances
Technical Feasibility Study of a Novel Wearable Capnograph (MARIE) in an Emergency Care Environment, Part 1
This study is testing a new wearable device that tracks carbon dioxide levels in patients during ambulance rides to see if it can improve monitoring and help start treatment faster.

What this trial studies
This study evaluates the technical feasibility of a novel wearable capnograph, known as MARIE, designed to monitor exhaled carbon dioxide levels in patients during ambulance transport. By measuring these levels, the study aims to enhance patient monitoring and potentially initiate treatment sooner in emergency situations. The trial involves both healthy volunteers and patients being transported by ambulance, with data collected to assess the device's effectiveness in a real-world emergency care environment.
Who should consider this trial
Good fit: Ideal candidates include healthy volunteers aged 18-84 and patients aged 18-84 being transported by ambulance.
Not a fit: Patients requiring oxygen supply, those in priority 1 ambulance transports, or those unable to provide informed consent may not benefit from this study.
Why it matters
Potential benefit: If successful, this device could improve monitoring and treatment outcomes for patients during ambulance transport.
How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating this may be a novel exploration in emergency monitoring.
