A member asked:

Would chronically high catecholamines inducing vasoconstriction result in reduced cerebral blood flow and hypoxia? why or why not?

No: Hi. What do you mean by chronically high catecholamines? Do you have a pheochromocytoma or paraganglioma? Congestive heart failure? Please define what you call "chronically high catecholamines" (CHC). In no event would CHC cause hypoxia or reduced cerebral blood flow. Please provide meaningful information. Good luck and happy 2015!

Your meds: might be responsible if you do not have a pheochromocytoma. No hypoxia expected
