Nitric oxide is believed to contribute to regulation of blood flow by its selective binding to circulating hemoglobin (forming S-nitrosohemoglobin, SNO-Hb) and release in a PO2-dependent manner. This study is designed to test that hypothesis by measuring the effect of hypoxia and exercise on forearm blood flow before and after depletion of SNO-Hb using oral N-acetylcysteine.
