Typically, spirometry testing is used to diagnose asthma, chronic obstructive pulmonary disease (COPD), and other conditions that affect breathing. In asthma, spirometry is used to detect obstruction, the degree of obstruction, and the variability of obstruction.<\/p>\n
If you’ve already been diagnosed with a chronic lung disorder such as asthma, spirometry may be used periodically to monitor your lung and airway condition and check whether a treatment for your asthma is helping you breathe better, or whether your breathing problems are under control.<\/p>\n

A lower-than-normal FVC reading indicates restricted breathing. The ratio between FEV1 and FVC is used in the diagnosis of restrictive or obstructive lung disease. For healthy people, it is above 70%. The value is reduced for asthmatics and COPD patients showing the presence of an obstruction in the lungs or airways. Different from FEV1 alone, FEV1\/FVC ratio provides a relative indication of obstruction such as in asthma, and it is particularly useful in helping assess how well your asthma treatment or management is working or how your condition is progressing.<\/p>\n The maximum expiratory flow is an indication of the degree of obstruction in the airways. The value is reduced for asthmatics and COPD patients.<\/p>\n FVC, FEV1, FEV1\/FVC, and PEF together provide a good picture of how well your lungs and airways function.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/aimwellbreathing.com\/wp-content\/uploads\/2023\/03\/Spirometry-Testing-\u2013-An-Effective-Metric-Testing-for-Asthmatics.png” alt=”Spirometry Testing \u2013 An Effective Metric Testing for Asthmatics” title_text=”Spirometry Testing \u2013 An Effective Metric Testing for Asthmatics” _builder_version=”4.18.0″ _module_preset=”default” custom_margin=”|-16px||||” custom_padding=”|109px||58px||” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.18.0″ _module_preset=”d5b784bb-599d-45cd-8913-368139b885a3″ custom_padding=”16px||4px|81px||” global_colors_info=”{}”][et_pb_row _builder_version=”4.18.0″ _module_preset=”8f0b9145-2815-4315-bd9c-ddebf3fd0cdf” custom_padding=”0px||9px||false|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”cf912270-afff-45f4-982a-a96e27bc0067″ header_2_text_color=”#0C71C3″ header_2_font_size=”25px” global_colors_info=”{}”]<\/p>\n To Prepare:<\/strong><\/p>\n \u25cf You may need to stop using your inhaler beforehand.

How to Prepare and Perform a Spirometry Test<\/h2>\n
\u25cf Wear loose clothing that won’t interfere with your ability to take a deep breath.
\u25cf Avoid eating a large meal or drinking alcohol before your test.
\u25cf Avoid smoking for 24 hours before the test.
\u25cf Avoid heavy physical effort or exercise for at least 30 minutes before the test.<\/p>\n
\u25cf Follow the instructions to put on a breathing piece.
\u25cf Take a deep breath in as far as you could, then hold your breath for a few seconds before exhaling as hard and complete as you can into the breathing piece.
\u25cf Repeat the test three times to make sure that the 3 test results are consistent, then record the highest value.<\/p>\nSpirometry Criteria For Normal Condition<\/h2>\n
You can find your estimated normal values from relevant medical sources. Typically, for FVC, FEV1, and PEF, a ratio value of >= 80% of the estimate is considered normal. For FEV1\/FVC, >= 70% is considered normal.<\/p>\nHow to Use Spirometry to Diagnose and Manage Asthma<\/strong><\/h3>\n
\u25cf You could first find out your normal range for FVC, FEV1, and PEF.
\u25cf Record your spirometry results of FVC, FEV1, FEV1\/FVC, PEF.<\/p>\nSpirometry Criteria for Asthma<\/strong><\/h3>\n
\n\u25cf You should discuss with or visit your doctor for treatment or adjust the existing treatment.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.18.0″ _module_preset=”8f0b9145-2815-4315-bd9c-ddebf3fd0cdf” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”cf912270-afff-45f4-982a-a96e27bc0067″ global_colors_info=”{}”]In summary, spirometry is a highly effective metric for the diagnosis and management of your asthma. Further, It is not just a test for your lung health, but rather for human health. It is considered the fifth vital sign, in addition to Blood Pressure, Body Temperature, Heart Rate, and Breath Rate.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
