Summary

The supply of oxygen is essential for energy production, recovery from efforts, and human life. 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. According to our hypothesis, acute IHHE in elderly adults may influence cardiorespiratory condition, blood pressure, and arterial oxygen saturation. The 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. The placebo group will undergo a 5-cycle protocol with an FiO2 of 21%.

Interventions

Type	Name	Description
DEVICE	MITOVIT® Hypoxic Training System	The EG (Experimental Group) will undergo a single session of IHHE (Intermittent Hypoxia-Hyperoxia Exposure) session using the MITOVIT® Hypoxic Training System (COMMIT GmbH, Salzgitter, Germany). They will breathe air with an oxygen concentration (FiO2) ranging from 10-14% for 5 minutes, followed by 3 minutes of rest in hyperoxia (FiO2 30-40%), for a total of 6 cycles. During the hypoxic phase, oxygen saturation will be maintained between 85-92%, while during the hyperoxic phase, it will be kept above 95%. This process is regulated by the device's AI. Participants will be asked to sit and breath normally in each exposure. An attendance checklist will be used to monitor compliance with the intervention
DEVICE	Sham MITOVIT® Hypoxic Training System	The Sham Group (SG) will follow a single session protocol of 5 cycles of 6 minutes per session with an FiO2 of 21% using the MITOVIT® Hypoxic Training System (COMMIT GmbH, Salzgitter, Germany). Participants will be asked to sit and breath normally in each exposure. An attendance checklist will be used to monitor compliance with the placebo intervention.
