During a PSG for a female patient with anemia, how will transcutaneous monitoring values likely compare to normal values?

• A. Higher than normal values
• B. Lower than normal values
• C. Within normal range
• D. Unpredictable values

Answer: (B)

In cases of anemia, the oxygen-carrying capacity of the blood is reduced due to a lower concentration of hemoglobin. As a result, when performing transcutaneous monitoring during a polysomnography (PSG), it is expected that the values obtained will be lower than normal. This is because the transcutaneous monitor reflects the partial pressure of oxygen in the blood, which is directly impacted by the reduced hemoglobin levels found in anemic patients. Consequently, the lower hemoglobin leads to diminished oxygen saturation levels, resulting in lower transcutaneous monitoring values compared to what is considered normal in healthy individuals. This physiological response is crucial for understanding the impact of conditions like anemia on respiratory monitoring during sleep studies.
