Abstract: Determining and monitoring desaturation indices and instantaneous respiratory rate, based on extracting components from the blood oxygen saturation (SpO2) signal captured by an oximeter, obtaining and processing the data in the frequency domain in order to detect respiratory events and determine values such as respiratory rate and deviations therefrom (tachypnea/bradypnea) and desaturation indices. Bioengineering applications in the field of medicine include monitoring and assisting with the diagnosis of respiratory disorders for its use in anesthesia, intensive care units and healthcare emergencies and assisting in the diagnosis of sleep apnea/hypopnea syndrome (SAHS).

Abstract: Extraction of components of the a signal captured by an accelerometer, obtaining information about physiological data such as cardiac, respiratory and snoring activity. The extracted signal components are useful for the diagnosis of different types of abnormal respiratory phenomena during sleep (apneas, hypopneas and respiratory efforts associated to micro-arousals).
