The content links PaO2 to FiO2 and clinical factors such as age, altitude, and ventilation, emphasizing that PaO2 must be interpreted relative to FiO2. It explains oxygen saturation behavior using the oxyhemoglobin dissociation curve, including left/right shifts and the limits of oxygen delivery gains beyond PaO2 of 70 mmHg. It also covers PaCO2 causes of hypo- versus hyperventilation and normal and pathological acid-base patterns.",{"@graph":63,"@context":118},[64,80,101],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":11,"@type":70,"position":76},"https://docshare.wps.com/template/presentations/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/arterial-blood-gases-key-abg-interpretation-concepts/572785/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/arterial-blood-gases-key-abg-interpretation-concepts/572785.png","ImageObject",442,249,{"name":88,"@type":89},"nayy☆","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-20","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":73},"InteractionCounter",{"@type":100},"ViewAction",{"@type":102,"mainEntity":103},"FAQPage",[104,110,114],{"name":105,"@type":106,"acceptedAnswer":107},"How should PaO2 be interpreted in ABG results?","Question",{"text":108,"@type":109},"PaO2 must be interpreted in relation to FiO2.
