Measurement of arterial oxygen saturation by pulse oximetry was performed in two patients with acute and chronic anaemia (haemoglobin concentrations: 2.9 mmol/l (4.7 g/dl) and 1.9 mmol/l (3.0 g/dl), respectively) using a Radiometer OXI and a Nellcor N-200 pulse oximeter. The two oximeters read alternating different values in the two patients. In conclusion, pulse oximeters are able to give a value for oxygen saturation even at extreme anaemia, and when a high value is given, it possibly reflects arterial oxygen saturation. The value of pulse oximetry in severe anaemia is discussed.
使用Radiometer OXI和Nellcor N - 200脉搏血氧仪对两名急性和慢性贫血患者(血红蛋白浓度分别为2.9 mmol/l(4.7 g/dl)和1.9 mmol/l(3.0 g/dl))进行了脉搏血氧测定法测量动脉血氧饱和度。这两台血氧仪在两名患者身上交替读出不同的值。总之,即使在极度贫血时,脉搏血氧仪也能够给出血氧饱和度值,当给出高值时,它可能反映动脉血氧饱和度。本文讨论了脉搏血氧测定法在严重贫血中的价值。
