PeriScope is the state-of-the-art PC Windows* based Vascular Analysis System with interpretation PeriScope uses automatic simultaneous limb NiBP (Non-Invasive Blood Pressure) measurement and ECG waveform to calculate important parameters like Arterial Stiffness Index, Pulse wave velocities, Ankle brachial Index, Ejection slope etc. Additionally, it incorporates Oscillometric envelopes and interpretive monograms. These are established as independent markers to analyze the arterial stiffness and Atherosclerosis. PeriScope also calculates Mean Arterial Pressure, Pulse Pressure, %MAP, Ejection Time etc. All these parameters give a complete picture of vascular function of the patient. It is a very useful tool for prevention, detection and treatment follow up of vascular diseases. PeriScope has undergone extensive Clinical Trials on Normal Subjects and Patients with CAD, HTN, DM, CKD, RA etc. It has been validated for Repeatability and reproducibility. Based on these studies, a research paper "Validity and reproducibility of arterial pulse wave velocity measurement using new device with oscillometric technique: a pilot study" has been published in the international journal Biomedical Engineering Online.
