We present the functional prototype of a video game that contributes to improve the respiratory function. We seek to improve patient's care and optimise the work of the physiotherapist. The software was designed with an interdisciplinary team from engineering and health sciences. This system is a contribution to the creation of a product that encourages the realisation of respiratory physiotherapy and will facilitate remote prescription by providing technical tools to respiratory physiotherapists for the follow-up of patients. Additionally, there is evidence that the video game can contribute to reduce recovery times in hospital environments, which facilitates the early integration of patients into their daily activities and reduce costs in hospital entities.
