Matrics soltuin pulse oximeters work by emitting two wavelengths of light, usually red and infrared, into the body. Oxygenated and deoxygenated hemoglobin absorb these wavelengths differently. The pulse oximeter measures the amount of light that passes through the blood and calculates the oxygen saturation level based on the absorption differences. It also detects the pulsating component of blood flow, which allows it to determine the heart rate.

The oxygen saturation level indicates the percentage of hemoglobin in the blood that is bound to oxygen. Normal oxygen saturation levels typically range between 95% and 100%. Readings below 90% may indicate hypoxemia, which is a low level of oxygen in the blood and can be a sign of respiratory or cardiovascular problems.

Pulse oximeters are commonly used in various settings, including hospitals, clinics, and homes. They are especially helpful for monitoring patients with respiratory conditions, such as chronic obstructive pulmonary disease (COPD), asthma, or pneumonia. They can also be useful for athletes and individuals engaging in high-altitude activities.

It's important to note that pulse oximeters provide a snapshot of oxygen saturation and heart rate at the time of measurement. They do not provide a comprehensive assessment of a person's respiratory function or overall health. If you have concerns about your health, it is always best to consult a healthcare professional for a proper evaluation and diagnosis.
