Using Laser Spatiotemporal Photoplethysmogram and Computational Method for Management of Chronic Disorders.

Laser Spatiotemporal Photoplethysmogram and Computational Method for Extended Chronic Cardiometabolic Therapeutic Care

This investigational study is carried out to find out if a smartwatch monitor worn on the wrist that acts like a blood pressure monitor, will be able to replace the traditional blood pressure measurements using the traditional cuff that is wrapped around your arm.

NHC inpatients (Group A) Patients will be required to put on the LSPPG wearable sensor to take measurement once a day, starting from the day of recruitment till day of discharge. 3 ECG electrodes with cable linking to the LSPPG sensor wearable will also be attached on the chest. This helps to capture ECG rhythm at the same time. Study team member will assist the patient to take daily measurement.

NHC Outpatients scheduled for 24-Hour ABP monitoring (Group B) Patients will wear the LSPPG wearable sensor whilst wearing the 24-hour ambulatory blood pressure monitor. 3 ECG electrodes with cable linking to the LSPPG sensor wearable will also be attached on the chest. This helps to capture ECG rhythm at the same time. Readings will be obtained on an hourly basis during the duration of wearing the ambulatory blood pressure machine (clinical grade device).
