A spirometer is a medical device used to measure the amount of air inhaled and the time to exhale completely. An incentive spirometer is the main equipment used for basic Pulmonary Function Tests (PFTs) to check lung diseases such as asthma, bronchitis, and emphysema. The incentive spirometry test is undertaken to find the cause of shortness of breath, assess the effect of contaminants on lung function and the effect of medication, and evaluate progress for lung disorder treatment. The incentive spirometer goal entails - 

What is a Peak Flow Meter?

A peak flow meter is an affordable and portable device to measure the Peak Expiratory Flow (PEF) to help individuals manage their asthma symptoms and prevent an asthma attack. Patients must consult their doctor about their best PEF to provide a point of concern for PEF tracking in disease management. These meters are vital whether you or your child have moderate to severe asthma and require daily medications. Individuals with moderate-to-severe asthma should keep the peak flow meter handy.

Peak Flow Meter vs. Spirometer

Pulmonary Function Testing (PFT) is a noninvasive lung test that is normally performed to check the level of respiration in individuals. The spirometry test requires you to inhale and exhale into a tube to analyze the results. These results diagnose the individuals' respiratory level or vital capacity of the lungs. However, featured with unique techniques differentiated on the basis of benefits.

How to Use An Incentive Spirometer?

  1. Sit up on the edge of a chair or bed.
  2. Hold the incentive spirometer in an upright position at eye level.
  3. Put the spirometer mouthpiece in your mouth, close your lips tightly around it, and exhale normally.
  4. Exhale slowly as well as deeply through your mouth. While taking a breath, the piston or ball starts to rise toward the top of the chamber.
  5. You have to hold your breath for a few seconds or as long as possible holding your breath will let the piston fall slowly to the base of the meter.
  6. If the spirometer goal indicator rises above the marked points, slowly exhale.
  7. Remove the mouthpiece of the meter from your mouth.
  8. Exhale completely. The piston will reach back to the bottom of the chamber.
  9. After a moment of rest and you can repeat the same steps ten or more times.
  10. Slowly take some normal breaths between every deep breath to prevent dizziness. Repeat the process every 1-2 hours.
  11. Completing each set of 10 breaths, try to cough which will cleanse mucus buildup from your lungs.
  12. Mark the level up to which the piston reached will be your incentive spirometer goal for the next test.

Frequently asked questions

A spirometer is an instrument that measures the capacity of the lungs indicating the volume and speed of air breathed in and out. The purpose of using a spirometer is to check the health and functioning of the lungs.

During a spirometry test, the customer is asked to breathe into the mouthpiece attached to the spirometer. The device measures the rate at which air is inhaled and exhaled as well as the lung capacity thus determining the speed/flow and volume/amount of air breathed in and out. The measurement unit is FEV1 which is Forced Expiratory Volume in One Second.

An incentive spirometer determines how deeply one can inhale and is generally used during treatment of lung conditions such as pneumonia. The test involves taking in slower, deep breaths for expanding and filling the lungs with air.

Incentive spirometer has a breathing tube, an air chamber as well as an indicator. The breathing tube is attached to the air chamber with a mouthpiece at the end. The indicator can be found inside.

Follow the steps below to get an understanding of what the spirometer is telling you. Your doctor will of course do the diagnosis but this is just for your basic understanding.

  1. Take reading of the forced vital capacity (FVC)
  2. Take reading of the forced expiratory volume in one second (FEV1)
  3. If both FVC and the FEV1 are within normal range then this means your lung function is normal
  4. If FVC and/or FEV1 are decreased, this may be an indication of lung disease
  5. If FEV1/FVC readings indicate lung disease, check the % predicted for FEV1/FVC. If this is 69% or less then it suggests obstructive disease of the lungs
