Spirometry Testing Tips

You are convinced that in order to effectively and accurately assess the extent and management of obstructive lung disease, asthma or COPD if, spirometry is the essential test. You have been exposed to spirometry testing is performed or technique is shown for testing while attending a trade union congress, but you really need a refresher. Here are some tips.


You need to be aware that spirometry is an effort that depend test requires the full cooperation of the patient. In order to accomplish this, as the coach must be totally involved in the tests. Make sure the patient is comfortable. Make a note as to whether the patient is sitting or standing, because after that the patient must be made from the same position tests. If the patient is standing, have a chair behind him in case becomes lightheaded after the coup. It is generally a good idea to have the elderly sitting in the test. If he or she is wearing a shirt with a tight-fitting necklace, they have unbutton the top button and if the use of a tie, should be loosened.

Explain clearly and in simple terms he or she to perform an evaluation breathing. Try to avoid the word test as this has connotations passing or failing and may make the patient apprehensive. Point out that they are making a slow maximum inhalation followed by a maximum exhalation, but exhalation be as fast as they can and as hard as they can. Key coaching will continue to blow out for at least six seconds. I assure you it is quite normal to fly out for that time period. The American Thoracic Society in 1994 the Standardization of spirometry Update recommends that every six seconds hit the target for all spirometry testing.1
To garcontrazar the patient has a proper deep breathing, is valuable to emulate exactly what you expect. If the patient has a visual signal as to what a big deep breath is, and can actually see and hear a forced expiration, he Spirometry Testing she is more apt to do well. Body language is the key to good performance. Instruct the patient to put the mouthpiece between your teeth and do a good tight seal with his lips. After the patient slowly makes a maximal inspiration, the first phase of the trial, loudly urge the patient to blow. This element of surprise will help the patient to realize the fastest peak flow, which is the second phase of the test.

The third phase of the test, which involves the reduction of the flow, it is important to achieve the greatest possible volume in the patient’s FVC. Traditionally, technicians have instructions aloud to the patient to blow, blow, blow . . . go ahead, go ahead! For maximum forced volume, when the focus can be more effective.

Paul Enright said in a recent report that the use of soft sell may be best to achieve the best performance during the third phase. He says: . . . take the patient to care movement bell spirometer volume, the incentive computer screen, or audio tone detection current, demonstrating that he or she continues to leave some air . . . . Patients should be quietly told go ahead, I can see you are still getting more air. 2 The fundamental part of the test because a clogged patient may become the expulsion of a volume of air, but it may not seem obvious, and the test is stopped too soon. This results in a lower FVC than normal and when interpreted, may suggest that the patient is restricted. Many modern spirometer will give an error message when an abrupt cessation of flow so that a subsequent test can be performed properly seen. Another key indicator could be the taking note of the FET (forced expiratory time) is sometimes shown as part of the data. If time were significantly less than six seconds, this also suggests that patient test ended too quickly.

It is now recognized that if the patient blows hard for six seconds (FEV6), this should be considered a substitute for FVC3, and is suitable for most spirometry tests with obstructive lung disease. Therefore, it is imperative that you get your patient to fly out as long as possible. You might be surprised how long obstructed the patient can continue to blow.
