Star Trek-like technology offers noninvasive monitor for patients and athletes

30.04.2009
How long will it take to develop Star Trek-like medical technologies? The gap between science fiction and reality is closing faster than many people may think.

A noninvasive, needle-free system that uses light to measure tissue oxygen and pH will soon be an alternative to the painful use of needles to draw blood and cumbersome equipment to determine metabolic rate. The futuristic system, dubbed the Venus prototype, is being developed by Dr. Babs Soller and her colleagues. It has the capability to measure blood and tissue chemistry, metabolic rate (oxygen consumption) and other parameters.

The sensor and portable monitor are funded by the National Space Biomedical Research Institute (NSBRI) for use in space. Soller said the technology’s multiple, real-time applications will be beneficial to astronauts in their day-to-day activities and to critically ill patients on Earth.

“Tissue and blood chemistry measurements can be used in medical care to assess patients with traumatic injuries and those at risk for cardiovascular collapse,” said Soller, who leads NSBRI’s Smart Medical Systems and Technology team. “The measurement of metabolic rate will let astronauts know how quickly they are using up the oxygen in their life-support backpacks. If spacewalking astronauts run low on oxygen, the situation can become fatal.”

Placed directly on the skin, the four-inch by two-inch sensor uses near infrared light (that is just beyond the visible spectrum) to take the measurements. Blood in tiny blood vessels absorbs some of the light, but the rest is reflected back to the sensor. The monitor analyzes the reflected light to determine metabolic rate, along with tissue oxygen and pH. One unique advantage of Dr. Soller’s near infrared device is that its measurements are not impacted by skin color or body fat.

A noninvasive system also means a reduced risk of infection due to the lack of needle pricks. Most of the system’s development has occurred at the University of Massachusetts Medical School, where Soller is a professor of anesthesiology. She has worked closely with researchers at NASA Johnson Space Center in Houston to develop applications of the Venus system for space.

Former NASA astronaut and NSBRI User Panel Chairman Dr. Leroy Chiao said Soller’s sensor system and other technologies being developed for spaceflight are a wise investment.

“The neat thing about the work being done is that it is a two-for-one deal,” Chiao said. “Not only is this research going to help future astronaut crews and operations, it has very real benefits to people on the ground, especially to people in more rural areas.”

On Earth, there are several areas of health care that could benefit from Venus. However, it is patients treated by emergency personnel on ambulances and on the battlefield that could benefit the most from the technology.

“Eventually, we expect first-responders would have these devices, which would provide feedback on the severity of a person’s injury,” Soller said. “Data can be communicated directly to the hospital. Early access to this type of information may increase a victim’s chances of survival.”

The system’s Earth applications are not limited to urgent care. It will allow doctors to more efficiently monitor pediatric and intensive care patients. Athletes and physical therapy patients also stand to gain from the technology’s ability to measure metabolic rate and to assist in determining the level of activity or exercise that is most beneficial to the individual.

“Athletes would benefit from using these parameters in developing training programs that will help them improve their endurance and performance,” she said. “And we suspect the same thing will be true for patients in physical rehabilitation.”

Currently, Soller and her collaborators are working on several aspects to prepare the sensor for integration into spacesuits by reducing its size, increasing its accuracy in measuring metabolic rate, and developing the capability to run on batteries. These activities will also speed its application in helping to care for patients on Earth.

Soller’s technology is one of a group of innovative medical systems being developed by NSBRI to provide health care to NASA astronauts in space and to improve health care on Earth.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
