Dr. Zur With Cnoga Medical In The Himalayas


On May 29th, 1953 Edmund Hillary, a New Zealander, and Tenzing Norgay, a Nepali Sherpa, completed the first successful documented ascent of Mt. Everest via the southeast ridge.



The efforts to reach Everest’s summit began in the beginning of the last century, the desire existed however it incorporates great difficulty.

Obstacles such as the weather conditions, dilution of oxygen and a great physical effort do not deter many climbers from all around the world to try to succeed where others have failed.


The Challenge

Dr. Zur (The Israeli Center for treatment of Dizziness and Balance) accepted the challenge to climb Mt Everest. He recruited his research team to his study of “The effect of dilution of oxygen and barometric pressure on the sense of balance”.

Up until now, the basis of the research was in artificial testing environments using large and fixed measurement instruments in different populations, but not in a natural environment. The expedition members pitched in and agreed to undergo several testing throughout the climb.



Planning the Experiment

Dr. Oz Zur contacted Prof. Eli Carmeli and Dr. Jacob Fogelman of Haifa University to help plan the experiment.



Find the right Tools

Following the recommendation of Prof. Carmeli, Dr. Oz contacted Cnoga Medical LTD who provided their revolutionary non-invasive device.

This device quickly and easily monitors physiological parameters such as hemodynamic blood pressure with no need of cumbersome inflating pumps, pulse rate, oxygen saturation and so on. All can be easily monitored using the lightweight portable finger-mounted device completely non-invasively (no blood drawing is required).

Another instrument used in this experiment is a surface made of special polystyrene, which measures the sense of balance in the “Zur Balance test”. Throughout the climb, they will measure the sense of balance in order to assess whether various balance tests could be sensitive enough to show the climbers balance changes during the oxygen dilution in the air and the descending barometric pressure.

High altitude equilibrium disorders can be catastrophic, injuries and long falls may result in serious injuries or death therefore prior knowledge of the hiker’s ability will prepare him appropriately.


Preliminary Results

  • The findings of the first pilot research showed that as climbers increased height, up to 5,000 meters ASL, the total “Zur Balance test” score of equilibrium decreased. While increasing in altitude, the functional ability to perform the test declined and showed a decrease in the blood saturation parameter as well.
  • Another interesting fact was that the two best scores were of the Nepalese porters, who live at high altitude and on which the effect of the oxygen dilution and low barometric pressure was the least evident,  which explains their better functional performance in the test.
  • The best way for climbing in high altitude is slow ascending and proper layovers for the body to adjust. This allows measuring physiological changes with portable equipment and may prevent unnecessary bruising and injuries. A simple and easy test measures the equilibrium level.



About the Devices

Dr. Oz:The devices we received from Cnoga Medical performed flawlessly under critical conditions and showed results that reflected the harsh environment and helped when one of the expedition’s members needed to oxidize.”

Dr. Segman, founder and CEO of Cnoga Medical: “We are happy for the opportunity to collaborate with Dr. Zur Oz’s expedition to the Himalaya demonstrating that our devices perform accurately & reliably even under extreme conditions.”

Cnoga Medical has developed a new generation of futuristic-like devices that measure chemical and physiological parameters (including blood count, Glucose, blood pressure, hemoglobin etc.) noninvasively by the innovative technology of vascular color photography.

It has been widely known for many years that it is possible to use the spectrometric photography of blood vessels for measuring different biological parameters. The revolutionary idea of Cnoga Medical is using a standard color camera, which uses the image sensor as a color spectrometer, along with complex algorithms to create a reliable product.

After extensive research, Cnoga Medical succeeded to overcome the barriers in an original and innovative way and to stabilize the technology to a commercial readiness.

Dr. Segman adds; “Cnoga Medical’s technology allows measuring parameters in other fields as well such as food and beverages, security, cosmetics etc. without contact with the object. The company registered several patents which creates a primary status in the market of noninvasive camera sensor based measurement instruments, a fact that will facilitate our rapid business expansion.”

Cnoga’s product line is in the midst of an aggressive commercial rollout globally. In addition, The Company plans two projects in the Far East with local market leaders to implement a Healthcare and patient management Cloud-Based system, in a novel approach of providing a complete solution for the next generation of diagnostic and preventative medicine.
