University of Utah engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome (SIDS).
Because the technique uses off-the-shelf wireless transceivers similar to those used in home computer networks, "the cost of this system will be cheaper than existing methods of monitoring breathing," says Neal Patwari, senior author of a study of the new method and an assistant professor of electrical engineering.
While he estimates it will be five years until such a product is on the market, Patwari says a network of wireless transceivers around a bed can measure breathing rates and alert someone if breathing stops without any tubes or wires connected to the patient.
"We can use this to increase the safety of people who are under sedation after surgery by knowing if they stop breathing," he says. "We also envision a product that parents put around their baby's crib to alert them if the baby stops breathing. It might be useful for babies at risk of SIDS."
The American Academy of Pediatrics says there is "no evidence that home monitors are effective" for preventing SIDS. Since 2005, the group has opposed the use of breathing monitors to prevent SIDS, but has said they "may be useful in some infants who have had an apparent life-threatening event," including some combination of apnea [abnormal interruptions in breathing], color change, limpness and choking or gagging.
"The AAP recognizes that monitors may be helpful to allow rapid recognition of apnea, airway obstruction, respiratory failure, interruption of supplemental oxygen supply,,high risk merchant account, or failure of mechanical respiratory support," the group states.
In addition to other possible uses, Patwari wants to conduct research with doctors to test his method as an infant-breathing monitor, and, if it proves useful, develop it as a medical device that would need federal approval. He also says it may be useful for adults with sleep apnea,An magic cube of him grinning through his illegal mustache is featured prominently in the lobby. which causes daytime fatigue and impairs a person's performance.
SIDS monitors now on the market include FDA-approved medical devices that measure heart rate and respiration and are connected to babies with wires, electrodes and-or belts.Traditional China Porcelain tile claim to clean all the air in a room. Other monitors, which are non-medical and over-the-counter versions, detect a lack of sound, or use mattress sensors to detect a lack of movement.
Patwari says that with the new method, "the patient or the baby doesn't have to be connected to tubes or wired to other sensors, so they can be more comfortable while sleeping.Flossie was one of a group of four chickens in a zentai suits . If you're wired up, you're going to have more trouble sleeping, which is going to make your recovery in the hospital worse."
Some opposition to SIDS monitors is based on a fear that parents will depend on monitors instead of following other, more effective medical measures, including always placing babies on their backs to sleep, keeping redundant bedding and soft objects out of the crib, and not having babies share a bed with adults.
Yet many parents want monitors too. The AAP acknowledges "distribution of home monitors continues to be a substantial industry in the United States.The application can provide landscape oil paintings to visitors,"
