Pulmonary function tests

Pulmonary Function Tests (PFTs)

Pulmonary Function Tests (PFTs) are tests that measure how well the lungs are working. They can detect abnormalities that may be caused by a variety of lung diseases including Chronic Obstructive Pulmonary Disease (COPD) and asthma. PFTs are often used to diagnose, monitor and guide treatment of lung diseases. The tests measure the amount of air and gas exchanged in your lungs, how much effort it takes to breathe, and how different medications and treatments affect your breathing.

Preparation For Pulmonary Function Tests

Before your tests, you may be told to leave any items of clothing that could interfere with the test at home and to avoid eating and drinking anything except for water. Your doctor may also ask you to stop taking certain medications that could affect the test results. You may also be asked to sit quietly for up to 15 minutes prior to the test in order to get a baseline resting reading.

Procedure for Pulmonary Function Tests

To do the test, you will need to sit or stand in a special pulmonary testing laboratory. You will be given a mouthpiece or mask to breathe into. The device will measure how much air is entering your lungs and how much oxygen is in the air you exhale. You may be asked to inhale and exhale quickly or deeply in order to get an accurate reading.

Types of Pulmonary Function Tests

  • Spirometry: A spirometry test measures how much air you can exhale, how quickly you can exhale, and how much oxygen is in the air you exhale
  • Oximetry: An oximetry test measures the amount of oxygen in your blood by attaching a small device to your finger
  • Multi-Breath Lung Volumes Measurements: This test measures the size and capacity of your lungs
  • Lung-Capacity Test: This test measures how much air you can hold in your lungs at a single time
  • Diffusion Capacity Measurements: This test measures how well your lungs are able to diffuse oxygen

Risks Of Pulmonary Function Tests

There are no significant risks associated with pulmonary function tests. You may experience some shortness of breath or dizziness during the test, but this is normal and should not last for more than a few moments.

Why are Pulmonary Function Tests Done?

Pulmonary function tests are used to diagnose and monitor a variety of lung diseases and conditions. They can help your doctor determine if you have asthma, COPD, or any other lung diseases. PFTs can also be used to monitor your response to treatment for these conditions.

When are Pulmonary Function Tests Needed?

Pulmonary function tests are typically recommended for those who have symptoms of a lung condition, such as shortness of breath, wheezing, or coughing. It is also recommended for those who have been exposed to pulmonary irritants, such as fumes or smoke. Your doctor may also recommend pulmonary function tests if you are taking medications for a lung condition.

Read the following passage carefully and answer the questions given below.The Italian banking system became the model for those North European nations that would achieve the greatest commercial success in the coming centuries, notably the Dutch, the English, and the Swedes. It was in Amsterdam, London and Stockholm that the next decisive wave of financial or innovation occurred, as the forerunners of modern central banks made their first appearance. The seventeenth century saw the foundation of three distinctly novel institutions that, in their differen in ways, were intended to serve a public as well as a private financial function. The Amsterdam Exchange Bank, i.e. the Wisselbank, was set up in 1609 to resolve the practical problems created for merchants by the circulation of multiple currencies in the United Provinces, where there were no fewer than fourteen different mints and copious quantities of foreign coins. By allowing merchants to set up accounts denominated in a standardized currency, the Exchange Bank pioneered the system of cheques and direct debits or transfers that we take for granted today. This allowed more and more commercial transactions to take place without the need for the sums involved to materialize in actual coins. Financial historians disagree as to how far the growth of banking after the seventeenth century can be credited with the acceleration of economic growth that began in Britain in the late eighteenth 20 5 century and then spread to Western Europe, North America and Australasia. But banks played a more important role in continental European industrialization than they did in England's.a) Where did the precursors of modern central banks make their first appearance? b) What practical problem was the Wisselbank required to resolve in its initial days?c) How did the Amsterdam Exchange Bank respond to the demand of the age? d) What are the points of disagreement among the financial historians with respect to growth of banking vis-a-vis growth of economy? e) Choose a suitable title for above composition.
