Abdominal Respiration Induces Hemodilution and Related Reduction in ADH Concentration of Blood

Abstract To establish effective lymph drainage methods and develop concise and accurate clinical techniques for evaluating lymph drainage in healthy individuals and patients with cancer treatment-related lymph edema, we investigated the numbers of red (RBC) and white (WBC) blood cells, and platelets (PLT) in blood, hematocrit (Ht), and the blood concentrations of total protein (TP), albumin (Alb), and anti-diuretic hormone (ADH) before and after 5 min manual lymph drainage, followed by 30 min rest with or without abdominal respiration in the supine or sitting position in 48 healthy volunteers. The 5 min facial, upper and lower extremities lymph drainage, followed by 30 min rest in the supine position induced significant reductions of the TP and Alb in all subjects, and their RBC and Ht levels in some subjects. The 30 min rest only in the supine position without lymph drainage produced also significant reductions of blood TP and Alb. In addition, abdominal respiration in the supine position without manual ...
