  • Chronic Bronchitis

Inflammation and irritation of bronchial tubes result in chronic bronchitis. The impacted individual may realize a persistent cough that lasts at least three months. This duration can even extend and when overlooked, the present symptoms may drastically worsen.

  • Chronic Obstructive Pulmonary Disease

Shortness of breath, wheezing or a chronic cough are some of the symptoms realized by the individual suffering from chronic obstructive pulmonary disease.

  • Lung Cancer

Cancer is a disease in which the volume of cells grows beyond control. The fundamental causes of this deadly condition are smoking, exposure to harmful toxins and even family history.

  • Thickened, stretched, or enlarged airways
  • Weakness of the muscles in the chest

How To Prepare For A Pulmonary Function Test?

If you have been suggested a Pulmonary Function Test, it is imperative to implement certain guidelines before heading towards the examination centre. Because PFT’s fundamental motive is to assess the true nature of your lungs and thus it becomes vital to pay heed to the instructions.

Your doctor will explain the examination in detail and what you can expect. The professional will also apprise you about the dos and don’ts. Should you have any confusion, it is advisable to clear it out right away.

Here is a list of instructions that you must follow to prepare for your pulmonary function test.

  • Don’t smoke before the test if you do so. This can play a deterrent in achieving accurate results. Rather you should discuss it with your doctor and they will tell you how long before the examination you should stop.
  • The intake of alcohol should also be ditched before the examination. Overlooking this parameter may tamper with the accuracy of the outcome.
  • On the day of the examination, maintain a safe distance from heavy meals.
  • Steer clear of any sort of strenuous exercises at least 30 minutes before the imaging.
  • Do you use a short-acting inhaler often? If yes, try not to employ it for 6 to 8 hours before the test.
