Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An assesment of an optical system that measures blood pressure on the finger -Elfor 1 device. The system is based on a small optical sensor that emits coherent light into the skin and collects the reflected light from the red blood cells in the blood vessels in the skin under the sensor. The sensor is able to detect the pulse wave and blood pressure can be measured.

The investigators plan to measure blood pressure with the new sensor in patients who are attending the Hypertension Clinic at Meir Hospital or are undergoing hemodialysis to validate the sensor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

If the blood flow is temporarily interrupted by inflating a small pneumatic cuff at the root of the finger, blood flow is occluded and the pulse wave disappears. As the pressure in the cuff is released, blood flow returns, the pulse wave is again detected and blood pressure can be measured. This apparatus is easy to use and will allow simplified monitoring of blood pressure contains the laser source and optical sensors that measure the reflected light.

The investigators proposed to validate the sensor by measuring the blood pressure in patients with this optical sensor and also by standard plethysmography. The investigators plan to measure participants with low, normal and high blood pressure in order to assess the accuracy and reliability of the new device.

Blood pressure measurement

Patients requiring blood pressure measurement will have their blood pressure measured in the standard manner by plethysmography, and then with the Elfor -1 device , the new optical sensor, in order to determine the performance of the new sensor.
