New England Journal of Medicine, 2003•Mass Medical SocNitric oxide, a key factor in the maintenance of vascular tone, causes vascular smooth
muscles to relax. Hemoglobin rapidly destroys nitric oxide, thereby limiting the activity of the
gas to the local environment. Recent work suggests that nitric oxide reacts with hemoglobin
at high oxygen tensions to form relatively long-lived products. At low oxygen tensions, these
products release vasodilatory nitric oxide. This work is controversial, but it provides evidence
of the potential of inhaled nitric oxide as a therapeutic agent.
