Device: Polso Wearebale watch
Registration Number
NCT03448861
Lead Sponsor

Brief Summary

ChroniSense Medical Ltd. is developing a wearable medical multi-parametric monitoring system, Polso™. Polso™ provides a number of the parameters employed in various Early Warning Scores (EWS), such as the National Early Warning Score (NEWS), utilised widely in UK hospitals.

The EWS is a physiological track and trigger system that is generated from multi- parameter or aggregate of vital signs measurements for early recognition of clinical deterioration in acutely admitted patients. Patients who are admitted into hospital are monitored with routinely measurements of these parameters that are manually recorded on a clinical chart.

Detailed Description

ChroniSense Medical Ltd. is developing a wearable medical multi-parametric monitoring system, Polso™. Polso™ provides a number of the parameters employed in various Early Warning Scores (EWS), such as the National Early Warning Score (NEWS), utilised widely in UK hospitals.

The EWS is a physiological track and trigger system that is generated from multi- parameter or aggregate of vital signs measurements for early recognition of clinical deterioration in acutely admitted patients. Patients who are admitted into hospital are monitored with routinely measurements of these parameters that are manually recorded on a clinical chart.

The parameters of the NEWS include: 1) respiratory rate pulse rate, 2) oxygen saturations, 3) body temperature; 4) systolic blood pressure, 5) heart rate, and 6) level of consciousness. Polso™ acquires, derives, and processes a number of physiological parameters. While ECG is not currently employed in NEWS, other parameters which are used in NEWS are available in the Polso™ system. In cases where manual testing is preferred for any parameter, such as use of supplemental oxygen, the individual score can be entered into the system manually. Polso™, as a wrist-based device, could enable a degree of flexibility in patient care and management.

The goal of this study is to evaluate the suitability of Polso™ as a data acquisition and processing platform capable of providing EWS summaries, against the currently employed NEWS system at the Milton Keynes University Hospital (MKUH) Cardiology Unit. The Polso™ will be employed strictly as a data-gathering system, and will not be used to influence any clinical decisions; the standard NEWS as currently employed will fulfill all its normal clinical roles.
