Mathematics in Medicine

Have you ever heard about the "importance of mathematics in medicine"? Do you believe it? How can we use our mathematical knowledge in this field?

Just follow the text and you will find the answer!

We will look together for a mathematics in a result of medical assessment named SPIROMETRY.

A Medical Assessment

##
Spirometry?

Spirometry is a medical assessment which helps doctors to test the pulmonary function - function of our lungs. Practically, it measures the movement of air into and out of the lungs.

##### Spirometry in the past

One of the first constructed spirometers was named WATER SPIROMETER. As you can see at the picture (left), the patient was breathing into a machine. Simultaneously, the machine was drawing the graph - spirometry curve.

##### Spirometry today

Modern spirometers are small computer machines connected to the breathing mouthpiece (picture right). Assessment result is printed out.

Spirometry Result

To help a doctor make a diagnosis, the modern spirometry result does not contain only siprometry curve, but also

o Key measured values

o Volume-Time curve

o Flow-Volume loop

o Comparable values (values, which should be achieved by a healthy man/woman)

Our task for the next pages is to find out how the computer creates this result. And also find out what the numbers and curves can tell the doctor about the patients' healthy conditions.

Mathematics hidden inside

##
What can I expect from Mathematics?

o Functions and its characteristics

o Graphs and formulas

o Derivatives

o Reading with understanding

o Deduction

And much more...

Is it difficult?

Do I Need To Know 'a lot of' Mathematics?

The answer is NO. Do not worry! The only thing what you need is a little bit of time and to have a fancy for thinking ;).
