Hemoglobin mass and blood volume in patients with altitude-related polycythemia

Schmidt, Walter FJ; Wachsmuth, Nadine; Jiménez, Jesús; Soria, Rudy (Frontiers in Physiology, 2022)

Patients with chronic mountain sickness (CMS) have a high hemoglobin concentration [Hb] due to increased hemoglobin mass (Hbmass) and possibly reduced plasma volume (PV). The values of Hbmass, PV and blood volume (BV) have ...
