Garmin Venu 3 versus Venu 4: comparing smartwatch vital sign measurements with a hospital monitor
Comparing the Garmin Venu 3 / Garmin Venu 4 for Non-Invasive Vital Sign Monitoring to a Hospital-Grade Monitor
This project will test whether the Garmin Venu 3 and Venu 4 smartwatches can accurately measure heart rate, breathing rate, and blood oxygen compared with a hospital-grade monitor in adult inpatients.

What this trial studies
This interventional comparison places a Garmin Venu 3 or Venu 4 on hospitalized adults and records vital signs simultaneously with a clinically validated Philips IntelliVue X2 monitor. Heart rate, respiratory rate, and SpO₂ from the smartwatch are collected alongside reference measurements and are compared quantitatively for accuracy and agreement. Participants also complete a brief smartwatch rating questionnaire to capture wearability and user experience. The goal is to determine whether these consumer devices produce reliable data that could be used for remote monitoring, earlier discharge decisions, or chronic disease management.
Who should consider this trial
Good fit: Adults aged 18 or older who can give informed consent, speak Dutch, and are hospitalized at least another 24 hours at Ziekenhuis Oost-Limburg are ideal candidates.
Not a fit: Patients who are in infection isolation, have a life expectancy under 30 days, or require continuous advanced monitoring may not benefit from smartwatch-based monitoring.
Why it matters
Potential benefit: If successful, these widely available smartwatches could provide a lower-cost, more accessible way to monitor vital signs remotely and support earlier discharge and chronic care outside the hospital.
How similar studies have performed: Prior studies have shown mixed results, with wrist-worn devices often measuring heart rate reasonably well but showing variable accuracy for respiratory rate and SpO₂, so clinical validation remains limited.
