A pulse oximetry reading provides crucial information about the oxygen saturation level in a patient's blood. A reading of 91% indicates a reduction in oxygen saturation that falls below the normal range, which is typically between 95% and 100%. This level suggests possible hypoxemia, wherein there is not enough oxygen reaching the tissues.

When evaluating oxygen saturation, readings below 92% often result in clinical concern and may necessitate further evaluation or intervention. In many clinical settings, a saturation level below 90% is particularly alarming and usually calls for prompt medical attention. Thus, the reading of 91% clearly signifies a problematic level that could indicate respiratory distress or other serious underlying health issues.

The higher readings of 93%, 95%, and 97% are within the acceptable range for oxygen saturation, meaning they do not typically indicate immediate concern for a lack of oxygen in the blood, even though they could still be monitored based on the patient's overall clinical picture.
