During a physical exam at a doctor’s office or hospital, a range of different devices are used to evaluate, monitor, and diagnose an individual. For the heart and respiratory system, there are stethoscopes. For the eyes, there are ophthalmoscopes and retinoscopes. And, for the ears, there are otoscopes.
In addition, tools like ultrasound, blood pressure monitors, pulse oximeters, and similar products designed to measure certain aspects of medical health are an integral part of making an accurate diagnosis in a reasonable time frame. These tools are the best way for medical professionals to ensure that each patient receives the best possible health care.
