The most likely reason for low blood oxygen levels despite proper blood circulation is a malfunction in the patient's respiratory system.
If a patient has low blood oxygen levels despite proper blood circulation, the most likely reason for this is a problem with the respiratory system. Specifically, the lungs may not be effectively oxygenating the blood. This can be caused by conditions such as lung diseases (e.g., chronic obstructive pulmonary disease, pneumonia), pulmonary edema, or a ventilation-perfusion mismatch. In such cases, it is important to seek medical attention for a proper diagnosis and treatment.
