Using a Universal Vital-Signs Thermometer for Remote Monitoring utilizing a Cloud-Based Rules Engine

Background: Attempts to implement telemedicine systems have been limited by low compliance rates, the inherent limitations of wrist-based monitors and the lack of actionable data.

Aims: The objective is to collect actionable medical data based on classic vital signs plus complementary data, in a user-friendly and simple manner, using a thermometer-shaped device.

Methods: A thermometer-like device for measuring vital signs was developed, where this device measures respiratory rate (RR), heart rate and blood oxygenation (SpO₂), in addition to oral temperature. This device calculated the RR by measuring the temperature changes of the insperium/experium at the nostrils, and uses a reflective PO sensor held against the philtrum.

Results: The RR measurements were evaluated in a clinical trial against a capnograph in a clinical trial. The ability to accurately measure RR values up to 65RPM was demonstrated.

Conclusions: Vital signs can be accurately measured at the mouth, enabling this approach to be a leading contender for implementing telemedicine systems generating actionable data.
