Intermittent Hypoxia-Hyperoxia Exposure (IHHE) is a novel technique in which the subject is exposed to a respiratory environment with reduced oxygen fraction, controlled through a specific software, using a facial mask and a hypoxic generation device. The objective of this study is to determine if there is a relationship between intermittent hypoxia-hyperoxia exposure and cardiorespiratory condition, blood pressure, and arterial oxygen saturation.\n\nAccording to our hypothesis, acute IHHE in elderly adults may influence cardiorespiratory condition, inflammatory biomarkers, blood pressure, and arterial oxygen saturation.\n\nThe study will be conducted as a randomized clinical trial. The subjects will be divided into two groups: the experimental group will undergo an IHHE session, breathing air with an oxygen concentration (FiO2) ranging from 10-14% for 1-5 minutes, with 1-3 minutes of rest in hyperoxia (FiO2 30-40%) for a total of 4-8 cycles, based on their acute response to hypoxia.
