The guide defines spirometry and explains how it differentiates obstructive and restrictive disorders and determines severity using predicted normal values. It emphasizes training, staff competence, and maintaining equipment accuracy through cleaning, regular checks, calibration, and quality control. Patient technique, preparation, manoeuvre steps, and quality criteria are detailed, including acceptable repeats and limits on attempts, to support accurate, reproducible results.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/spirometry-practical-guide-and-test-interpretation-use-of-spirometry-pre-lung-surgery/462490/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/spirometry-practical-guide-and-test-interpretation-use-of-spirometry-pre-lung-surgery/462490.png","ImageObject",300,407,{"name":42,"@type":43},"Danger Angel","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-30",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",13,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What does spirometry measure and why is it clinically important?","Question",{"text":63,"@type":64},"Spirometry measures lung function by the volume of air a patient can expel from the lungs after a maximal inspiration.
