Abstract: The invention relates to a communication method for communicating monitoring data between a monitoring device (4) and processing means (6), wherein the monitoring device (4) is configured for receiving the monitoring data. The method comprises the steps of sending a byte frame to the processing means (6), storing the byte frame, ordering the byte frame by separating the frame into respiratory rate bytes, heart rate bytes and additional bytes, and repeating the previous steps with a predetermined frequency until the processing means have received a heart rate data set, a respiratory rate data set, and an additional data set. The processing means create heart rate information from the heart rate data set and create respiratory rate information from the respiratory rate data set and display them to a user.
