Medical instruments are really important for helping doctors examine patients and understand their health. Some key tools they use are the stethoscope, otoscope, sphygmomanometer, and thermometer. Each one helps in a different way during check-ups.

1. Stethoscope:

   • This tool is used in about 80% of exams. It helps doctors listen to heartbeats, breathing, and stomach sounds.
   • Research shows that when doctors use a stethoscope along with other checks, they can accurately diagnose heart problems 88% of the time.

2. Otoscope:

   • This tool is for looking into the ear and checking the eardrum. It’s especially important for kids, as they often get ear infections.
   • About 70% of children will have an ear infection by age three, so using an otoscope early is really important.

3. Sphygmomanometer:

   • This tool measures blood pressure, which is a vital sign of heart health. About 29% of adults in the U.S. have high blood pressure.
   • Keeping track of blood pressure can lower the chances of serious heart problems by 50% if it’s managed well.

4. Thermometer:

   • This tool checks body temperature to find out if someone has a fever, which can be a sign of infection.
   • In doctor’s offices, getting a precise temperature reading can improve decision-making by 20%, especially when figuring out infections.

In summary, using these medical instruments helps doctors give better exams and leads to healthier patients. These tools are crucial for making sure that evaluations are thorough, which is key for accurate diagnosis and treatment.
