Obstructive sleep apnea (OSA) is a disorder that primarily affects the respiratory system and occurs during the sleep period. (OSA) is a respiratory disorder related to common sleep, characterized by repetitive obstruction of the upper airway, intermittent hypoxemia and recurrent awakenings during sleep. The absence of this stimulus generates a lack of respiratory effort, because the diaphragm muscle is not being stimulated. People with this disorder increase the risk of suffering fatigue, daytime sleepiness, psychological disorders, cardiovascular problems and respiratory and physical weakness, among many others. For this reason, the present project presents an electronic device that allows the measurement and / or detection of physical variables related to the diagnosis of OSA, using LabVIEW software. The developed device is non-invasive, designed to measure the distance of the thoracic cavity, the nasal …
