Emergencies involving children are rare events. Due to the associated lack of routine and special features in pediatric resuscitation, it is prone to errors and the results are unsatisfactory. One way of tackling this problem is to use assistance services. However, due to the process, these services cannot be easily integrated. One possibility is the use of Head Mounted Displays. These are often controlled via voice commands. With medical terms, the voice control implemented as standard can quickly become unusable. A wearable app was therefore developed for this paper and evaluated according to ISO/IEC 30122-2:2017 to determine the extent to which the voice control of a state-of-the-art smartglass works in quiet and noisy conditions for use during a resuscitation. Since the commands were well understood and the app could be reliably controlled, the use of voice control in an assistance service is conceivable.
