Why the study?

Remote patient monitoring is needed for resource limitations and infection control, but current sensors require physical contact that can cause discomfort or non-adherence.

Does a novel contact-free optical system accurately measure heart and respiratory rate compared to a standard bedside monitor?

Population

115 patients who completed study procedures

Comparison

Contact-free optical system (Gili Pro BioSensor) vs standard reference bed-side monitor (Mindray)

Overview

May enable comfortable remote vital-sign monitoring; leaves open larger validation before clinical adoption.

Structured PICO

Does a novel contact-free optical system accurately measure heart and respiratory rate compared to a standard bedside monitor?

P
Population
115 patients, mean age 66 ± 14.6, 60% male, 31% obese (BMI > 30 kg/m2).
I
Intervention
Contact-free optical system measuring nano-vibrations and movements (Gili Pro BioSensor)
C
Comparator
Standard reference bed-side monitor with electrocardiogram and capnograph modules (Mindray)
O
Outcome
HR and RR accuracy (HR in subjects without active arrhythmias, RR in all subjects)surrogate

A novel contact-free optical system demonstrated over 99% accuracy in detecting heart and respiratory rate compared to standard bedside monitors.
