In an adult man,there is about how much grams of hemoglobin in the circulating blood
PURPOSE: A standardized carbon monoxide (CO) rebreathing procedure with measurements of CO-hemoglobin, hemoglobin concentration (), and hematocrit (Hct) enables to determine total Hb mass (Hb(tot)), blood, erythrocyte, and plasma volume (BV, EV, and PV). These calculations are normally based on venous blood samples. However, micromethods also allow determinations from capillary blood. METHODS: The accuracy of using capillary blood for Hb(tot), BV, EV, and PV determination was evaluated in 42 men (age: 25.1 +/- 4.0 yr, body mass: 80.3 +/- 9.6 kg) by comparison of capillary and venous data. RESULTS: Capillary Hb(tot) (962 +/- 110 g) Ref Robbins 9/e pg 420 and internet
