FAQs
How do you perform spirometry?
There are multiple steps for completing a spirometry test. For visual reference, you can review a video on how to perform a spirometry test by clicking the video button below.
- Take time to create a rapport with the patient—effective communication and participation between the patient and medical professional results in more consistent and robust testing results.
- Accurately measure the patient’s height.
- Carefully and correctly enter the patient data into the spirometer.
- Demonstrate the correct techniques and maneuvers to the patient prior to completing the test.
- Use body language to coach for a maximal inhalation.
- Loudly prompt them to BLAST out the air.
- For the next six seconds, quietly encourage the patient to continue BLASTING by saying, “keep going, keep going.”
- Monitor the patient carefully during the maneuvers.
- Obtain a good test session with a quality grade (A or B).

Open in new tabHow long does a spirometry test take?
A spirometry test typically takes 10 to 15 minutes, depending on the patient’s ability to follow instructions and complete the required breathing maneuvers. The test involves taking a deep breath and forcefully exhaling into a spirometry device multiple times to achieve accurate results.
Healthcare providers may repeat the test after administering a bronchodilator to assess lung function improvement. Proper coaching and technique are essential for reliable measurements.

Open in new tabHow to coach a patient to perform spirometry
The typical spirometry exam is a three-phased process – each with their own coaching techniques to help patients produce an effective test.
- Phase 1
In the first phase, the goal is to instruct the patient on the proper techniques to apply their mouth to the spirometry mouthpiece. Best results are achieved when the patient takes a deep, deep breath, placing the mouthpiece between their teeth, and sealing the mouthpiece with their lips. - Phase 2
The second phase is the BLAST. This is when the patient will blow out as hard and as fast as possible. Coaching a patient in this phase is best achieved by developing a rapport with them prior to the exam, as the tester will learn which level of coaching is best for that individual patient. - Phase 3
The final phase is the remaining 5 to 6 seconds of exhalation. In this phase, you’ll quietly encourage the patient to “keep blowing” to complete the exhalation.

What are the important parameters in spirometry?
A spirometry test will produce a series of results or parameters that help medical professionals easily complete this exam. The three most important spirometry parameters are the FEV1, FVC, and FEV1/FVC ratio parameters.

Open in new tabWhat indications are used for spirometry?
There are multiple patient-symptoms or medical conditions that justify the use of spirometry. A few of the most common indicators include:
- To manage asthma and COPD patients
- Evaluate shortness of breath
- Perform surveillance for occupational-related lung disease
- Evaluate former or current smokers over the age of 45 for COPD
- Classification of COPD. (COPD is an umbrella term that covers multiple respiratory diseases including chronic bronchitis, emphysema, and idiopathic pulmonary fibrosis (IPF))
- Monitor disease progression
- Measure response and progress due to treatment, medication, and respiratory therapy
- Smoking cessation
Open in new tabWhat spirometry tests do your devices offer?
The EasyOne Air, Easy on-PC, and EasyOne Sky spirometry devices can perform the following tests:
EasyOne Air: FVC, FVL, SVC, MVV and pre/post testing
Easy on-PC: FVC, FVL, SVC, MVV, provocation challenge testing, and pre/post testing
EasyOne Sky: FVC, FVL, Pre/Post-testing
Open in new tabWhat’s the difference between an incentive and diagnostic spirometer?
An incentive spirometer is primarily designed to encourage deep breathing and promote lung expansion. It is often used as a respiratory therapy device for patients recovering from surgery.
On the other hand, a diagnostic spirometer is a more comprehensive and precise device used for assessing lung function. It is primarily used in clinical settings by healthcare professionals to measure and evaluate various respiratory conditions. The spirometry results aid in the diagnosis, monitoring, and management of respiratory conditions such as asthma, COPD, and other lung diseases. Diagnostic spirometry devices provide more detailed and precise measurements for diagnostic and clinical purposes.
