non-invasive monitoring techniques

Non-invasive monitoring techniques assess health without breaking the skin or entering the body. These methods use devices to measure vital signs, such as heart rate, blood pressure, oxygen levels, and brain activity, through sensors placed on the skin or at a distance. Examples include pulse oximeters that clip onto a finger, wearable fitness trackers, and imaging techniques like ultrasound. They provide important health information quickly and comfortably, reducing risks associated with invasive procedures. These tools are essential for continuous monitoring, early detection of issues, and improving patient comfort and safety.
