Comparative Measurement of Microcirculation and Other Parameters With the Vital USA VitalDetect™ in Patients With Diabetes Mellitus Type 1 and Type 2 Versus Healthy Participants

Comparative Measurement of Microcirculation and Other Parameters With the Vital USA VitalDetect™ in Patients With Diabetes Mellitus Type 1 and Type 2 Versus Healthy Paricipants

The purpose of this clinical study is to optimize the measurement algorithm of the Vital USA VitalDetectTM in measuring the microcirculating blood flow. Further optimization and finally the demonstration of the performance of the VitalDetectTM non-invasive monitoring biosensor in monitoring glucose, and heart rate in patients with type 1 and type 2 diabetes and healthy participants, when operated according to the instructions for use.

The study procedures will be the same for all three groups during the single visit. In all groups of participants, the Vital USA VitalDetect™ will be individually introduced and assigned. During the experimental study visit, microcirculating blood flow (MBF), heart rate, and SpO2 will be measured using the Vital USA VitalDetect™ at 2 time points in between approx. 15 min. MBF will be measured in parallel by use of the LEA Medizintechnik O2C also using a finger on the same hand. The YSI glucose measurements will be employed to generate a robust algorithm for glucose measurements using the VitalDetect™. Parallel measurements of the heart rate and the SpO2 using a patient monitor (Edan iM8b) will be compared to the Vital USA VitalDetect™ device readings. Venous blood will be drawn from every subject to determine proinsulin, insulin and HbA1c values.
