  1. Spirometry measures two main components: Forced vital capacity (FVC) and Forced expiratory volume (FEV1)12.The following are important measures provided by spirometry2:
    • Forced expiratory volume in 1s (FEV1): the volume exhaled in the first second after deep inspiration and forced expiration, similar to PEFR.
    • Forced vital capacity (FVC): the total volume of air that the patient can forcibly exhale in one breath.
    • FEV1/FVC: the ratio of FEV1 to FVC expressed as a percentage.

    Spirometry measures two main components: Forced vital capacity (FVC). FVC is the highest amount of air you can forcefully and completely blow out after taking a deep breath in. Forced expiratory volume (FEV1). FEV1 is the amount of air you blow out in one second.

    What is a spirometry module?
    The spirometry modules are developed with the Association of Respiratory Technology & Physiology (ARTP) and supported by the British Thoracic Society (BTS). • Baseline testing Used to investigate lung function where diagnosis has not been established. • Reversibility testing May help to differentiate asthma from COPD.

    How to use a spirometer?

    Dr. Anet Varghese

    Doctor of Medicine (MBBS) · 1 years of exp

    An incentive spirometer is often recommended by doctors after a lung surgery or lung-related illness such as pneumonia. Follow these steps while using one. Sit up and hold the device The first step involves the proper sitting position to have accurate results. Sit on a chair or bed with your back completely straight. Hold the spirometer at eye level. Do not tilt the meter to get results. Place the mouthpiece in your mouth and tightly seal it with your lips. Sealing the meter is important to ensure proper exercises and no loss of air pressure while exercising. With the mouthpiece in the mouth, slowly breathe out through your mouth. Do not breathe too hard as it would shoot the balls to the top of the chamber, breathing very slowly will not make the balls move at all. As you inhale the pistons or balls in the chamber will go up. Try taking in the breath as much as you can and try to hold the balls on the measurement mark. Take a break of a few seconds and repeat the cycle. Do not worry if you can’t get to a higher mark or cannot hold your breath for long, everyday exercises will improve your performance. Repeat the step mentioned above about breathing in and out for 10-15 breaths or as per the recommendation of your doctor. Your doctor may prescribe you a weekly target on the spirometer.

    What are the different types of spirometers?
    Spirometers are classified into closed-circuit and open-circuit spirometers. Closed-circuit spirometers are further sub-classified into wet and dry spirometers, which consist of a piston or a bellow acting as an air collecting system and a supported recording system that moves at the desired rate.

    What are the minimum specifications for a spirometer?
    The minimum specifications for a spirometer are the ability to measure a volume of 8L with an accuracy of ±3% or ±50ml with a flow measurement range of ±141 and a sensitivity of 200ml/s. It is recommended that the spirometer record at 15 s of the expiration time for the forced maneuver.

    What are the results of spirometry?
    The main results of spirometry are forced vital capacity (FVC), forced expiratory volume exhaled in the first second (FEV1), and the FEV1/FVC ratio. The procedure of spirometry has 3 phases: 1) maximal inspiration; 2) a “blast” of exhalation; 3) continued complete exhalation to the end of the test.
