Engineers at the University of Utah to build wireless networks that see through walls technology are now destined for a new goal: a noninvasive way to measure the respiration of surgical patients, adults with sleep apnea and babies at risk of syndrome sudden infant death (SIDS).

Because the technique uses standard wireless transceivers, similar to those used in home computer networks, the cost of this system will be cheaper than existing methods of monitoring breathing, said the professor of electrical engineering, Neal patwari.

While estimating that the product has only been on the market within five years, until such product on the market, said patwari a network of wireless transceivers around a bed can measure respiration rates and warn someone to stop breathing no pipes or wires attached to the patient.

"We can use this technology to increase the safety of persons who are under sedation after surgery to see if they stop breathing. We also think a product that parents can put around the crib to alert them if the baby stops breathe. It may be helpful for babies at risk of SIDS, "he said.

The American Academy of Pediatrics (AAP) said that "There is no evidence that home monitors are effective" to prevent SIDS. Since 2005, the group opposed the use of respiration monitors to prevent SIDS, but said "they can be useful in some children who had an event with apparent life-threatening," including a combination of apnea [abnormal interruptions in breathing ], color change, weakness and suffocation or choking.

"The AAP recognizes that the monitors can be useful to permit the rapid recognition of apnea, airway obstruction, respiratory failure, the interruption of supplemental oxygen, or the failure of mechanical respiratory support," the group said.

In addition to other possible uses, patwari or conduct research with the doctors to test their method to monitor a baby's breath, and if he prove to be useful to develop it as a medical device that needs federal approval. He also said that the method can be useful for adults with sleep apnea, which causes daytime fatigue and affect a person's performance.

The SIDS monitors currently on the market include FDA-approved medical devices that measure heart rate and breathing and babies are connected to wires, electrodes and / or belts. Other monitors, which are non-medical versions and free sale, failure to detect the sound or use sensors in the mattress to detect the lack of movement.

Patwari said that with the new method, "the patient or the baby need not be connected to tubes or wires connected to the other sensors so that they can be more comfortable during sleep. If you are connected to wires, you will have more trouble sleep, which will make your worst recovery in the hospital. "

The opposition to the monitors of SIDS based on fear that parents rely only on the monitors instead of following other medical measures more effective, as always putting your baby to sleep face up, keep covered, super soft pillows or mattresses that may cause the baby to choke and sink or soft objects out of his crib, and not cause the baby to sleep in their parents' bed.

However, many parents want to monitor as well. The AAP recognizes that "the distribution of home monitors continues to be an important trade in the United States." To read this story in full (in English), click here. http://unews.utah.edu/news_releases/catching-a-breath-wirelessly
