In modern healthcare, monitoring vital signs early and consistently can make a significant difference in patient outcomes. One compact yet highly effective device that plays a key role in this process is the pulse oximeter. Commonly used in hospitals, clinics, and home care settings, it helps individuals and healthcare providers keep track of oxygen levels and heart rate with ease. So, what makes a pulse oximeter so widely used, and why has it become a standard monitoring tool? Let’s explore its purpose and value in everyday healthcare. What Is a Pulse Oximeter? A pulse oximeter is a non-invasive medical device designed to measure the level of oxygen saturation (SpO₂) in the blood, along with the pulse rate. Oxygen saturation indicates how well oxygen is being delivered through the bloodstream to essential organs such as the heart and brain. Most pulse oximeters are lightweight, portable, and fit comfortably on a fingertip. They provide results within seconds on a digital display. Bec...
