Can pulse oximeter detect anemia? Despite her poor clinical condition and profound anemia (Hb, 2.7 g/dL), pulse oximetry continued to demonstrate a high O2 saturation percentage. Manipulation of Beer’s law shows that anemia theoretically should not affect pulse oximetry values.
Is oxygen saturation normal in anemia? An anemic patient may not have enough function- ing hemoglobin in the blood to oxygenate the tissues. The small amount of functioning hemoglobin in the blood may be well saturated with oxygen, so the patient may have a normal SpO2 reading, but the patient may not have enough oxygen going to the tissues.
Does anemia cause low oximeter readings? Although anemia does not change the ratio of oxyhemoglobin to deoxyhemoglobin, severe anemia can cause underestimation of SpO2, especially in hypoxemic subjects, mainly because pulse oximeters are calibrated on healthy subjects without anemia [2,3].
Can pulse oximeter detect hemoglobin? Pulse oximetry is a valuable non-invasive tool that provides data regarding the percentage of hemoglobin molecules loaded with oxygen in arterial blood in patients with normal oxygen-dissociation curves.
