conditions by measuring how much air you can breathe out in one forced breath.<\/strong><\/p>\n<p>It\u2019s carried out using a\u00a0device called a spirometer, which is a small machine attached by a cable to a mouthpiece.<\/p>\n<p>Spirometry may be performed by a nurse or doctor at your GP surgery, or\u00a0it may be carried out during a short visit to a hospital or clinic.<\/p>\n<p><strong>Why spirometry is carried out<\/strong><\/p>\n<p>Spirometry can be used to help diagnose a lung condition if you\u00a0have symptoms, or if your doctor feels you\u2019re at an increased risk of developing a particular lung condition.<\/p>\n<p>For example,\u00a0spirometry may be recommended if you have a persistent\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/cough\/\">cough<\/a>\u00a0or\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/shortness-of-breath\/\">breathlessness<\/a>, or if you\u2019re over 35 and smoke.<\/p>\n<p>Conditions that can be picked up and monitored using spirometry include:<\/p>\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.nhs.uk\/conditions\/asthma\/\"><strong>asthma<\/strong><\/a>\u00a0\u2013 a long-term condition where the airways become periodically inflamed (swollen) and narrowed<\/li>\n<li><a href=\"https:\/\/www.nhs.uk\/conditions\/chronic-obstructive-pulmonary-disease-copd\/\"><strong>chronic obstructive pulmonary disease (COPD)<\/strong><\/a>\u00a0\u2013 a\u00a0group of lung conditions where the airways become narrowed<\/li>\n<li><a href=\"https:\/\/www.nhs.uk\/conditions\/cystic-fibrosis\/\"><strong>cystic fibrosis<\/strong><\/a>\u00a0\u2013 a genetic condition where the lungs and digestive system become clogged with thick, sticky mucus<\/li>\n<li><a href=\"https:\/\/www.nhs.uk\/conditions\/idiopathic-pulmonary-fibrosis\/\"><strong>pulmonary fibrosis<\/strong><\/a>\u00a0\u2013 scarring of the lungs<\/li>\n<\/ul>\n<p>If you\u2019ve already been diagnosed with 1 of these conditions, spirometry may be carried out to check the severity of the condition or see how you\u2019re responding to treatment.<\/p>\n<p>Spirometry is also a standard test for people being considered for surgery, or to check the general health of people who have other conditions, such as\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/rheumatoid-arthritis\/\">rheumatoid arthritis<\/a>.<\/p>\n<p><strong>Preparing for the test<\/strong><\/p>\n<p>You\u2019ll be told about anything you need to do to prepare for the test.<\/p>\n<p>If you use\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/bronchodilators\/\">bronchodilators<\/a>\u00a0(medicines, usually inhaled, that help relax and widen your airways), you may need to stop using it beforehand.<\/p>\n<p>You should also avoid smoking for 24 hours before the test, and avoid drinking alcohol, strenuous exercise or eating large meals for a few hours beforehand.<\/p>\n<p>It\u2019s best to wear loose, comfortable clothing on the day of the test.<\/p>\n<p><strong>What\u00a0happens during a spirometry test<\/strong><\/p>\n<p>You\u2019ll be seated during the test and a soft clip will be placed on your nose to stop air escaping from it.<\/p>\n<p>The tester will explain what you need to do, and you may be asked to have a few practise attempts first.<\/p>\n<p>During spirometry, you\u2019ll be asked to take a deep breath and blow into a small tube (spirometer).<\/p>\n<p>When you\u2019re ready for the test, you\u2019ll be asked to:<\/p>\n<ul class=\"wp-block-list\">\n<li>inhale fully, so your lungs are completely filled with air<\/li>\n<li>close your lips tightly around the mouthpiece<\/li>\n<li>exhale as quickly and forcefully as you can, making sure you empty your lungs fully<\/li>\n<\/ul>\n<p>This will normally need to be repeated at least 3 times to ensure a reliable result.<\/p>\n<p>Sometimes, the test may need to be repeated around 15 minutes after\u00a0taking some inhaled bronchodilator medicine.<\/p>\n<p>This can show if you have a lung condition that responds to these medicines.<\/p>\n<p>Overall, your appointment\u00a0should last around 30 to 60 minutes. You\u2019ll be able to go home after the tests have finished and return to your normal activities.<\/p>\n<p><strong>Your results<\/strong><\/p>\n<p>The person carrying out the test\u00a0won\u2019t usually be able to give you your results immediately.<\/p>\n<p>The results will need to be\u00a0looked at by a specialist first and will then be sent to the\u00a0clinician who referred you for the test, who will discuss\u00a0them\u00a0with you a few days later.<\/p>\n<p>A spirometer measures the amount of air you can breathe out in one second and the total volume of air you can exhale in one forced breath.<\/p>\n<p>These measurements will be compared with a normal result for someone of your age, height and sex, which will help show if your lungs aren\u2019t working properly.<\/p>\n<p>The measurements will also show whether any problem with your lungs is \u201cobstructive\u201d, \u201crestrictive\u201d, or a combination of the two:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>obstructive airways disease<\/strong>\u00a0\u2013 where your ability to breathe out quickly is affected by narrowing of the airways, but the amount of air you can hold in your lungs is normal (such as in asthma or COPD)<\/li>\n<li><strong>restrictive lung disease<\/strong>\u00a0\u2013 where the amount of air you can breathe in is reduced because your lungs are unable to fully expand (such as in pulmonary fibrosis).<\/li>\n<\/ul>\n<p><strong>Risks and side effects<\/strong><\/p>\n<p>Spirometry is a straightforward test and is generally considered very safe. Some people may\u00a0feel\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/dizziness\/\">dizzy<\/a>, faint, shaky, sick or tired for a short period afterwards.<\/p>\n<p>Most people are able to have a spirometry test safely. But the test increases the pressure inside your head, chest, stomach and eyes as you breathe out, so it may need to be delayed or avoided if you have a condition that could be made worse by this.<\/p>\n<p>For example, spirometry may not be safe if you have, or have recently had, unstable\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/angina\/\">angina<\/a>, a\u00a0<a href=\"https:\/\/www.nhs.uk\/conditions\/heart-attack\/\">heart attack<\/a>, uncontrolled\u00a0<a href=\"https:\/\/www.nhs.uk\/Conditions\/Blood-pressure-(high)\/Pages\/Introduction.aspx\">high blood pressure<\/a>, or an operation to your head, chest, stomach or eyes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Please read the below if you have an upcoming Diagnostic Spirometry &amp; FeNo Breathing Test: INFORMATION FOR PATIENTS If you do not follow this information,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-475","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/pages\/475","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/comments?post=475"}],"version-history":[{"count":0,"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/pages\/475\/revisions"}],"wp:attachment":[{"href":"https:\/\/surgerywebtemp.org.uk\/c82009\/wp-json\/wp\/v2\/media?parent=475"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
