It serves as an educational resource outlining clinical indications for performing PFTs, such as the evaluation of dyspnea, assessment of disease severity, monitoring of treatment response, and determining fitness for surgery. The content covers core physiological principles of spirometry, static lung volumes, and diffusing capacity (DLCO), while establishing a systematic approach for clinicians to identify obstructive, restrictive, mixed, and vascular pulmonary patterns. It aims to enhance clinical decision-making through comprehensive understanding of respiratory physiology and standardized testing measures.",{"@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/interpretation-of-pulmonary-function-tests-pfts/390374/",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/interpretation-of-pulmonary-function-tests-pfts/390374.png","ImageObject",300,407,{"name":42,"@type":43},"Margaret","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-25",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",11,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What are the primary clinical indications for pulmonary function testing?","Question",{"text":63,"@type":64},"Clinical indications include evaluating patients presenting with dyspnea, assessing disease severity, monitoring responses to medical treatment, and determining patient fitness for surgeries such as thoracic surgery or lung resection.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"What are the three core measures of pulmonary function tests?",{"text":68,"@type":64},"The three core measures are spirometry, which assesses airflow;
