Pulse oximeter
A pulse oximeter is a small, portable device that measures the level of oxygen in a person's blood. It is often used on a fingertip, where it shines a light through the skin to estimate how much oxygen is being carried by red blood cells. This information is crucial for those with respiratory or cardiovascular conditions, as it helps monitor their oxygen saturation levels, ensuring they receive adequate oxygen, which is vital for overall health.
Using a pulse oximeter is easy and non-invasive. The device clips onto a finger, and within seconds, displays an oxygen saturation percentage on its screen. This immediate feedback helps individuals and healthcare professionals make timely decisions about medical care. It is particularly useful for people living at high altitudes or those experiencing symptoms of breathing difficulties.
During situations like pandemics, pulse oximeters have gained popularity as a home-monitoring tool. They allow people to track their oxygen levels and seek medical attention promptly if necessary. Always remember that while helpful, a pulse oximeter is not a substitute for professional medical advice.
