Why the study?
Does short-term oxygen administration reduce muscle sympathetic nerve activity in patients with chronic respiratory failure?
Does short-term oxygen administration reduce muscle sympathetic nerve activity in patients with chronic respiratory failure?
Patients with chronic respiratory failure exhibit marked sympathetic activation that is partially reversed by short-term oxygen administration, suggesting a role for arterial chemoreflex activation.
No takes yet. Share an insight, caveat, or question.
Oxygen may partially suppress sympathetic overactivity in chronic respiratory failure; hypothesis-generating and should not yet change practice.
Heindl et al. (2001) studied this question.
