The carbon monoxide re-breathing method can underestimate $ Hb_{mass} $ due to incomplete blood mixing
Purpose Hemoglobin mass ($ Hb_{mass} $) is commonly assessed using the CO re-breathing method with the subject in the seated position. This may lead to an underestimation of $ Hb_{mass} $ as blood in lower extremity veins while seated may not be tagged with carbon monoxide (CO) during the re-breathi...

| 520 | |a Purpose Hemoglobin mass ($ Hb_{mass} $) is commonly assessed using the CO re-breathing method with the subject in the seated position. This may lead to an underestimation of $ Hb_{mass} $ as blood in lower extremity veins while seated may not be tagged with carbon monoxide (CO) during the re-breathing period. Methods To test this hypothesis, CO re-breathing was performed on four occasions in nine male subjects, twice in the seated position and twice in combination with light cycle ergometer exercise (1 W/kg body-weight) intending to accelerate blood circulation and thereby potentially allowing for a better distribution of CO throughout the circulation as compared to in the seated position. Blood samples were drawn from an antecubital vein and the saphenous magna vein following the re-breathing procedure. Results In the seated position, CO re-breathing increased the percent carboxyhemoglobin (%HbCO) in the antecubital vein to 8.9 % (7.8–10.7) [median (min–max)], but less (P = 0.017) in the saphenous magna vein [7.8 % (5.0–9.9)]. With exercise, no differences in %HbCO were observed between sampling sites. As a result, CO re-breathing in combination with exercise revealed a ~3 % higher (P = 0.008) $ Hb_{mass} $, i.e., 936 g (757–1,018) as compared to 908 g (718–940) at seated rest. Conclusion This study suggests an uneven distribution of CO in the circulation if the CO re-breathing procedure is performed at rest in the seated position and therefore can underestimate $ Hb_{mass} $. | ||

This may lead to an underestimation of $ Hb_{mass} $ as blood in lower extremity veins while seated may not be tagged with carbon monoxide (CO) during the re-breathing period. Methods To test this hypothesis, CO re-breathing was performed on four occasions in nine male subjects, twice in the seated position and twice in combination with light cycle ergometer exercise (1 W/kg body-weight) intending to accelerate blood circulation and thereby potentially allowing for a better distribution of CO throughout the circulation as compared to in the seated position. Blood samples were drawn from an antecubital vein and the saphenous magna vein following the re-breathing procedure. Results In the seated position, CO re-breathing increased the percent carboxyhemoglobin (%HbCO) in the antecubital vein to 8.9 % (7.8–10.7) [median (min–max)], but less (P = 0.017) in the saphenous magna vein [7.8 % (5.0–9.9)]. With exercise, no differences in %HbCO were observed between sampling sites. As a result, CO re-breathing in combination with exercise revealed a ~3 % higher (P = 0.008) $ Hb_{mass} $, i.e., 936 g (757–1,018) as compared to 908 g (718–940) at seated rest. Conclusion This study suggests an uneven distribution of CO in the circulation if the CO re-breathing procedure is performed at rest in the seated position and therefore can underestimate $ Hb_{mass} $.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">nHb</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Red cell mass</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Blood volume</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CO</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">RCV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Siebenmann, Christoph</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bonne, Thomas Christian</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sørensen, Henrik</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Robach, Paul</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lundby, Carsten</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European journal of applied physiology</subfield><subfield code="d">Berlin : Springer, 1928</subfield><subfield code="g">113(2013), 9 vom: 16.

carbon monoxide re-breathing method can underestimate $ hb_{mass} $ due to incomplete blood mixing |

The carbon monoxide re-breathing method can underestimate $ Hb_{mass} $ due to incomplete blood mixing |
| abstract |
Purpose Hemoglobin mass ($ Hb_{mass} $) is commonly assessed using the CO re-breathing method with the subject in the seated position. This may lead to an underestimation of $ Hb_{mass} $ as blood in lower extremity veins while seated may not be tagged with carbon monoxide (CO) during the re-breathing period. Methods To test this hypothesis, CO re-breathing was performed on four occasions in nine male subjects, twice in the seated position and twice in combination with light cycle ergometer exercise (1 W/kg body-weight) intending to accelerate blood circulation and thereby potentially allowing for a better distribution of CO throughout the circulation as compared to in the seated position. Blood samples were drawn from an antecubital vein and the saphenous magna vein following the re-breathing procedure. Results In the seated position, CO re-breathing increased the percent carboxyhemoglobin (%HbCO) in the antecubital vein to 8.9 % (7.8–10.7) [median (min–max)], but less (P = 0.017) in the saphenous magna vein [7.8 % (5.0–9.9)]. With exercise, no differences in %HbCO were observed between sampling sites. As a result, CO re-breathing in combination with exercise revealed a ~3 % higher (P = 0.008) $ Hb_{mass} $, i.e., 936 g (757–1,018) as compared to 908 g (718–940) at seated rest. Conclusion This study suggests an uneven distribution of CO in the circulation if the CO re-breathing procedure is performed at rest in the seated position and therefore can underestimate $ Hb_{mass} $. |

Conclusion This study suggests an uneven distribution of CO in the circulation if the CO re-breathing procedure is performed at rest in the seated position and therefore can underestimate $ Hb_{mass} $.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">nHb</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Red cell mass</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Blood volume</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CO</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">RCV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Siebenmann, Christoph</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bonne, Thomas Christian</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sørensen, Henrik</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Robach, Paul</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lundby, Carsten</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European journal of applied physiology</subfield><subfield code="d">Berlin : Springer, 1928</subfield><subfield code="g">113(2013), 9 vom: 16.
