Every patient is given a small smart bracelet, which has a heart rate, sleep and step monitoring function and is connected via a secured WiFi Network. The nurses are able to see a live monitoring of the data eg. the heart rate. They can use an iPad to get a live monitoring or access old data of even single patient and don't have to walk to every single room during the night. This saves a lot of time - so there is more time for the nurses to actually take care of the patients, because of less time consuming routine check ups.
