Key result
Two hours of sustained hypoxia significantly increased muscle sympathetic nerve activity (P<0.01) and arterial blood pressure (P<0.05) in healthy volunteers, whereas cyclic hypoxia did not.
Why the study?
Does the pattern of hypoxia (sustained vs cyclic) influence sympathetic activity and hemodynamics in the postexposure period in healthy humans?
Population

May differentially affect post-exposure sympathetic activity; leaves open relevance to clinical hypoxic conditions.

p-value: p=<0.01
Two hours of sustained, but not cyclic, hypoxia significantly increases muscle sympathetic nerve activity and arterial blood pressure in healthy humans.
Tamisier et al. (2004) studied Healthy. Sustained hypoxia vs. Cyclic hypoxia was evaluated on Muscle sympathetic nerve activity and arterial blood pressure (p=<0.01). Two hours of sustained hypoxia significantly increased muscle sympathetic nerve activity (P<0.01) and arterial blood pressure (P<0.05) in healthy volunteers, whereas cyclic hypoxia did not.
