Correlations of peak oxygen consumption with haemoglobin saturation with oxygen, arterial oxygen content, haemoglobin, and arterial oxygen tension (group A, 20 heart failure patients and 20 normal controls)
| Sao2 | Cao2 | Hb | Po2 | |
|---|---|---|---|---|
| Data were obtained from means of three samples. | ||||
| Cao2, arterial oxygen content; Hb, haemoglobin; Po2, arterial oxygen tension; Sao2, haemoglobin saturation with oxygen. | ||||
