Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who are admitted to the emergency room or ICU without prior cardiac arrest and have relevant laboratory tests available.

Probably not a fit

Patients who experience sudden cardiac arrest outside the hospital or those with trauma may not benefit from this study.

What this trial studies

This observational study focuses on the high incidence and fatality rates associated with cardiac arrest, aiming to enhance the 'life chain' response for affected patients. It utilizes millimeter wave radar technology to detect micro motion signals from human respiration and heartbeat, which could potentially improve early warning systems and emergency responses. The study will analyze data from patients admitted to the emergency room or ICU at Peking Union Medical College Hospital over a specified period, assessing their conditions prior to cardiac arrest. The goal is to identify critical factors that can lead to better outcomes in cardiac arrest situations.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and intervention strategies for cardiac arrest, potentially saving lives and reducing neurological impairments.

How similar studies have gone: While the approach of using millimeter wave radar for early detection is innovative, similar studies have shown promise in improving emergency response systems for cardiac arrest.
