Swiss develop wireless cameras to monitor vital signs of premature babies


On Monday, Swiss researchers say they have developed a wireless camera system to monitor vital signs of premature babies. It was a move that could replace uncomfortable and highly inaccurate sensors.

Currently, the skin sensors used is to monitor vital signs in the prematurely babies born that  generate false alarms up to 90% of the cases. Those cases are mainly set up for the baby’s movement.

However, Jean-Claude Fauchere, a doctor at University Hospital Zurich’s neonatal clinic, explained in a statement that it’s a source of discomfort for babies; since they have to check it every time.

It has also become a significant stress factor for nurses and poor use of their time, it distracts them from managing real emergencies and can affect the better quality of care.

The hospital is to begin tests of a new, contactless system created by the researchers. Those researchers are at the EPFL polytechnical University Lausanne and at the Swiss Center for Electronics and Microtechnology, CSEM, in Neuchatel.

However, the system should allow premature babies kept warm in neonatal incubators to be mentally monitored. By the use of highly sensitive cameras that will detect the pulse of newborn babies by analyzing and detecting the skin color. Ultimately, it changes every slighter time.

“Breathing is monitored by measuring the movements of its movements and thorax, the infrared rays from the cameras take over at night, which means that the monitoring can be carried out non-stop.”

The CSEM researchers have designed the optical system, who is close to the cameras that are sensitive enough to detect minutes that changes in skin color. However, the EPFL researchers designed algorithms to process the data in the real time.

We can track this area with our algorithms, when the person moves. It isolate the skin pixels and use minor changes in their color for determining the pulse. And, the tests showed that the cameras produced practically the same results as conventional sensors.

“In addition to cutting down on false alarms, it would also be more comfortable for the babies.”
