Key drivers include trauma, obstetric complications such as amniotic fluid embolism, hemorrhage, malignant hypertension, cardiomyopathy, and eclampsia, plus iatrogenic and medical contributors like aspiration and sepsis. Pregnancy-related changes—reduced functional reserve capacity, rapid desaturation, altered gas exchange, decreased buffering, and uterine compression—necessitate BLS and ACLS modifications, including left-sided positioning, early advanced airway planning, adjusted ventilation, and prompt identification of reversible causes.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/cardiac-arrest-during-pregnancy-clinical-management-notes/370818/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/cardiac-arrest-during-pregnancy-clinical-management-notes/370818.png","ImageObject",300,407,{"name":92,"@type":93},"WPS_1786070896","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-09-23",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",14,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What are the most common causes of cardiac arrest during pregnancy?","Question",{"text":113,"@type":114},"Trauma or injury is listed as the most common cause.
