A single center, single blinded, prospective validation (including extension0 study for the accuracy and safety evaluation of Neteera 130H, a novel, radar-based contact-free device for heart and respiratory rate measurements.

This is a single-blinded, prospective validation study for the accuracy and safety evaluation of Neteera 130H, a novel, radar-based contact-free device for heart and respiratory rate measurements compared to reference devices.

Each subject will have a single study visit in which the subjects will be screened and upon eligibility confirmation, will undergo HR and RR measurements using the investigational device as well as the reference devices. In a previous clinical trial (NET-MED-002) 100 subjects were measured in the sitting position. In the extension study part (NET-MED-002-EXT), 70 eligible subjects, 18 years old and above, suffering from chronic medical conditions, will be enrolled. In this extension part, 70 of the subjects will be measured while randomly assigned into one of two groups - 35 subjects in group A (sitting position) and 35 subjects in sleep posture//group B (lying in bed/sleeping posture position) in a ratio of 1:1. Data from the previous study and the Extension study will be pooled for final analysis.
