- Swiss researchers have developed a wireless camera system to monitor vital signs in premature babies.
- Contactless system created by researchers at the EPFL polytechnical university in Lausanne and at the Swiss Centre for Electronics and Microtechnology, CSEM, in Neuchatel,
- It could replace uncomfortable and highly inaccurate skin sensors.
Current Technique issues
- Skin sensors are used for monitoring.
- The skin sensors currently used to monitor vital signs in babies born prematurely generate false alarms in up to 90% of cases, mainly set off by the baby’s movement.
- It will avoid the discomfort made by the sensors
- Also a significant stress factor for nurses and a poor use of their time – it distracts them from managing real emergencies and can affect quality of care
How it works
- The system should allow premature babies kept warm in neonatal incubators to be medically monitored using highly sensitive cameras.
- These cameras detect the newborn’s pulse by detecting and analysing its skin colour, which changes ever so slightly every time its heart beats.
- Breathing is monitored by measuring movements of its thorax and shoulders.
- At night, infrared cameras take over, which means that monitoring can be carried out non-stop
- The optical system was designed by CSEM researchers, who chose cameras sensitive enough to detect minute changes in skin colour.
- The EPFL researchers designed algorithms to process the data in real time.
The cameras developed is under testing which gives similar output asa the conventional snesors
