TY - JOUR T1 - Testing your lungs: spirometry JF - Breathe JO - Breathe SP - 257 LP - 260 DO - 10.1183/20734735.ELF143 VL - 14 IS - 3 A2 - , Y1 - 2018/09/01 UR - http://breathe.ersjournals.com/content/14/3/257.abstract N2 - Your healthcare professional will show you how to blow into the spirometer before you begin. You may need to wear a soft clip over your nose to stop air leaking out of your nostrils. Before starting the test, you might be asked to breathe in deeply and out gently into the spirometer. You will then be asked to blow at least three times, but usually no more than 10 times, into the spirometer. ER -
