Final answer:
A reading of > 95 on a pulse oximeter indicates normal oxygen saturation level, while lower percentages suggest low blood oxygen levels.
Step-by-step explanation:
A pulse oximeter is a device used to measure the oxygen saturation level in a patient's blood. A reading of > 95 indicates a normal oxygen saturation level. This means that the hemoglobin in the blood is carrying an adequate amount of oxygen throughout the body. Lower percentages would indicate hypoxemia, which is low blood oxygen levels.
For example, if a pulse oximeter reading is 92%, it suggests that the blood is not carrying enough oxygen to meet the body's needs. This can be a sign of respiratory or cardiovascular problems.
