Whole blood donation consists in the removal of 10% of total blood volume (500ml). In this situation several compensatory mechanisms occur, involving sympathetic nervous system, renin–angiotensin–aldosterone system and the release of erythropoietin. Aim of this study is to evaluate whether a periodic stimulation of sympathetic nervous system, such as in blood donors in the period following the donation, may affect lung function.
