Influence of haemoglobin oxygen saturation (Hb-sO2), haemoglobin mass (Hbmass) and blood volume on arterial oxygen content (CaO2)
| p Value | Estimate | CI (95%) | AUS day 12, (%) | BOL day 16, (%) | |
|---|---|---|---|---|---|
| Hb-sO2 (%) | <0.001 | 0.229 | 0.222 to 0.236 | 33 | 34 |
| Hbmass (g) | <0.001 | 0.0271 | 0.0264 to 0.0278 | 20 | 8 |
| Blood volume (mL) | <0.001 | −0.00395 | −0.00405 to −0.00384 | 42 | 55 |
Demonstrated are the results of an analysis of covariance (mixed model) and the calculated percentage contribution of Hb-sO2, Hbmass and blood volume on the compensation of CaO2 after ascent to altitude (difference from day 1).
