Abstract

Audio alarming system for medical devices requires attention at some very specific segments. The clinical environment is full of disturbances and every alarm sound is not an exception. This paper presents some aspects of (audio) alarming within clinical environment and associated problems. Low power operation and limited resources for implementation are just on top of the problems related to the user experience. The presented solution is following the specific standards and is flexible enough to provide audio signals, which can be generated with small microcontroller. The described alarm generator was evaluated in laboratory and during clinical evaluation in real clinical environment with patients. The results are presented at the end of the paper.
