Vital signs are those elements that characterize the being is alive. Variations, sometimes even if small, may indicate problems that, if are not perceived, can aggravate and endanger the person. The problem is that these signs are not easily discernible, much less to the naked eye, making it difficult to monitor these changes in pattern, making a late rescue. Thus a system was developed with the function to do this monitoring, alerting when detect a variation and indicating the possible problem. Was used in the project an Arduino Uno microcontroller and a zigbee communication network in order to use a means of communication wireless low power consumption and reliable transmission. The project therefore aims to develop a monitoring based on standard vital signs, sending to a central control an alert if there is a problem and indicate the possible failure, accelerating decision making and giving a better chance at survival of the monitored patient.
