Spirometry is a test that shows how well your lungs are working. It is used for diagnosing lung problems or to monitor how well you are responding to treatment. It can also help your healthcare provider choose the right treatment plan for you.

Your lungs need oxygen to breathe, but not enough of it gets into your bloodstream and to your body’s cells. That’s why your lungs can get tired and short of breath when you have breathing problems, such as asthma, chronic obstructive pulmonary disease (COPD) or rheumatoid arthritis. Spirometry is a simple, painless test that can help your doctor find out why you’re not getting enough oxygen and what kind of treatment will help.

A spirometer is a specialized machine that has a tube connected to it. It measures how fast and how much air you can exhale in a minute.

It’s a quick test, usually taking 5-30 minutes. It’s safe and generally considered very helpful. Some people feel dizzy, faint, shaky or sick for a short time after the test.

Your healthcare provider will tell you about what to do before the test and how to prepare for it. You may need to stop using bronchodilators (medicines that relax and widen your airways) for a while before the test.

You will be given an incentive Spirometer คือ, which helps loosen mucus and fluids that build up in your lungs. This will make your lungs stronger as you heal from surgery and lowers your risk of getting a lung infection during your recovery.

Before your spirometry appointment, you can ask questions about how to use your incentive spirometer. Your healthcare provider can talk with you and show you how to use the incentive spirometer and how to read your results.

The incentive spirometer is a tool that will expand your lungs by helping you take deep, slow breaths. It can also be used to help you practice your breathing exercises and make your lungs stronger as you recover from surgery.

An incentive spirometer is also helpful if you have an injury, such as a rib fracture. It can help loosen the ribs, so that you won’t have any pain when you breathe or cough. It can also help you learn how to clear out mucus that builds up in your lungs, which lowers your risk of getting a lung infections as you recover from surgery.

Using an incentive spirometer can improve your health, especially if you have COPD or asthma. It can also help you with other conditions that affect your lungs, such as lung cancer or pneumonia.

How to prepare for a spirometry test

To help you get the best results from your spirometry test, you should wear loose clothing. You should also avoid cigarette smoke or vaping, which can reduce the accuracy of your results. You should also be aware of any complications that might happen during or after your spirometry test.

Unless your healthcare provider says you can, it’s important to tell your healthcare provider about any medicines you take regularly (even over the counter ones) before the spirometry test. You should also let your healthcare provider know if you have an allergy or other condition that might affect your test.
