Hur episodisk hypoxi p?verkar blodtrycket hos friska ?ldre individer
Aim and Hypotheses The aim of the study was to investigate how episodic hypoxia affects resting blood pressure and the acute blood pressure response in healthy older adults. The following hypotheses were formulated for analysis in the study: Blood pressure increases acutely in healthy older adults during exposure to 150 minutes of hypoxia with SpO? 80%. Resting blood pressure decreases in healthy older adults after 15 repeated exposures of 150 minutes of hypoxia with SpO? 80% over a period of three to four weeks. Method Thirteen healthy older adults participated in a single-arm intervention study. Participants were exposed to hypoxia (SpO? 79.3%, 150 minutes) across 15 sessions distributed over three to four weeks. Blood pressure was measured at rest before and after the intervention period, as well as at five time points during each hypoxia session. Data were analyzed using paired t-tests and repeated measures ANOVA. Results The results showed that both systolic and diastolic blood pressure increased significantly during acute hypoxia exposure, while resting blood pressure measured before and after the intervention decreased significantly for both systolic and diastolic values. Conclusion Exposure to episodic hypoxia may potentially serve as an alternative or complementary method for regulating resting blood pressure in older adults. However, further studies are required to confirm the effects and to establish appropriate dosing protocols.
