Nowadays, healthcare has become extremely professional and advanced. With the help of several medical devices, doctors can diagnose a disease easily and provide the best treatment to their patients. Medical devices are also used to monitor any changes in the patient’s health condition during treatment. Say’s Dr. Jon Kiev, In this article we will discuss some of these important medical devices used in various hospitals around the world:

Pulse oximeter

Pulse oximeters are devices that measure the amount of oxygen in your blood. They’re used to monitor your heart rate, respiratory rate and blood pressure (among other things).

Pulse oximeters use light waves to detect how much oxygen is in your blood–and then calculate the amount of hemoglobin present as well as its saturation level. You might also hear this device referred to as an “oxygen saturation meter.”

They’re typically placed on the finger or earlobe and can be used in hospital settings or at home by people with certain medical conditions such as chronic obstructive pulmonary disease (COPD), pneumonia and heart failure.

Blood pressure monitor

Blood pressure monitors are used to measure the force of blood flow through arteries. They can be used to monitor high blood pressure, and they can also help diagnose heart failure.

Blood pressure monitors are used at home or in a doctor’s office to measure your blood pressure. You’ll need to wear an arm cuff that wraps around your upper arm and squeeze it tight enough so that it won’t move during measurement but not so tight that it hurts you–just like putting on a jacket!


A thermometer is a device used to measure body temperature, which can be helpful when determining if you’re sick or not. To use a thermometer, place it under the tongue and let it sit there for three minutes before taking it out and reading the number on the display screen.


A stethoscope is a medical device that is used to listen to the heart and lungs. It can also be used to listen to other organs, such as the stomach or intestines. A doctor will place the stethoscope on your chest and back, listening for different sounds that indicate problems in these areas.

Glucose meter

A glucose meter is a device that measures the amount of glucose in the blood. It’s used to test for diabetes, but it can also be used as an indicator of your overall health. Glucose meters are handheld devices that you prick your finger with and they give a reading on how much sugar there is in your system.


A nebulizer is a device that turns a liquid medication into a mist that can be inhaled. Nebulizers are used to treat asthma, cystic fibrosis, and other lung diseases as well as allergies or COPD (chronic obstructive pulmonary disease).

Nebulizers can also be used to administer drugs that aren’t inhaled directly into the lungs but instead need to dissolve in the mouth before being swallowed–for example: antibiotics for pneumonia treatment


In the end, it’s important to remember that medical devices are a vital part of our healthcare system. They allow us to monitor our health and keep track of how well we’re doing over time. As technology advances and new devices come out, we can expect them to become even more useful than they already are today!
