Vital sign device improves resuscitation monitoring

10.11.2003


American Heart Association meeting report



A small device can give doctors the "big picture" of patients’ vital signs, researchers reported today during the Resuscitation Science Symposium at the American Heart Association’s Scientific Sessions 2003.

The device, called "Vital Dust," transmits patient data to a hospital or centralized location, allowing others to see the data and also gain a global view of all patients in the field who are being similarly monitored. It measures heart rate and the percent of oxygen saturation in the blood, an important indicator of a person’s cardiopulmonary status. A radio transmits the information to a wearable or handheld computer, where it is displayed for a medical team.


"If there is a mass casualty event, having this information on all the victims will allow the emergency medical technicians to triage right then and there, giving the sickest people priority. In single-person casualties, we’ll know right away if the patient has a sudden change in status and needs immediate attention," said Matt Welsh, Ph.D., assistant professor of computer science at Harvard University, one of Vital Dust’s developers and lead author of the study.

"This advance may lead to a more rapid triaging system," said Steve Moulton, M.D., one of the researchers who tested the device.

Vital Dust consists of a small, low-power computer connected to a sensor that fits over the patient’s fingertip. It is about six centimeters by three centimeters, or the size of a pack of chewing gum. Vital Dust runs on two AA batteries and includes an embedded microprocessor, memory, and a wireless communication interface.

Another unique feature of Vital Dust is its ability to store the pre-hospital electronic medical record together with a record of the patient’s vital signs.

"This form of data management enables a copy of the pre-hospital record to travel with the patient, giving hospital-based personnel the ability to review what was done in the field and determine how those maneuvers may have influenced the resuscitation process," said Moulton.

Moulton and his study co-authors are integrating Vital Dust sensors with iRevive, a pre-hospital, mobile database, to automate the process of capturing patient information.

One of the unique features is that the radio can adjust the power for transmitting information, Welsh said.

"If a patient’s heart rate slows dangerously or his oxygen saturation level drops precipitously, the system will automatically adjust the transmission power so that a stronger signal is sent out and has a greater chance of being received by the paramedic," he said. "The radio would back off transmitting other patients’ data, thus giving a critical patient’s signal an even greater chance of going through." This is the first wireless network designed to give priority to victims that are in critical condition, Welsh said. "Continuous real-time monitoring of vital signs in the field should greatly improve the effectiveness of emergency medical care."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
