A 2026 blog post claims raising a person’s legs can help in a circulatory emergency and make CPR more effective. It does not cite clinical evidence, and it should not be treated as a substitute for emergency services, CPR or an automated external defibrillator. Current emergency guidance should take priority.
A blog post published in October 2026 proposes lifting an unresponsive person’s legs as a way to help when a bystander does not know CPR. The post claims this increases blood flow to the heart and lungs, but it cites no clinical evidence for its assertions and does not establish leg elevation as a substitute for calling emergency services, CPR or using an automated external defibrillator (AED).
The post, published by Book of Joe and attributed to a report titled “Beyond the Med Speak: How to Save a Life,” advises bending down, lifting the person’s feet and holding their legs around waist height. It describes the action as a simple measure for an “uninformed, unschooled, and scared” bystander. The post says raising the legs returns blood from the body’s periphery to the central circulation.
It also claims that leg elevation is equivalent to transfusing two units of blood, or 40% of an average adult’s circulating blood volume, and that it makes CPR more effective. The post gives no study, medical guideline or other source for those figures or claims. Its author says this is the first instruction they give when arriving at a “Code Blue” scene, but the post does not identify the author’s credentials or explain the circumstances in which the advice would apply.
Readers who witness a person collapse should follow instructions from their local emergency dispatcher. Standard emergency guidance emphasizes calling emergency services, checking responsiveness and breathing, and starting CPR or using an AED when indicated and available. The blog post does not describe how to assess the emergency or explain how its suggested action fits with those steps.
The Risks of Unverified First Aid
Advice aimed at people who feel unprepared can be influential during a time-sensitive emergency. A simple instruction may seem easier to follow than CPR, but readers need to know whether it is supported by medical guidance and whether it could delay other urgent steps.
The post’s blood-volume comparison is particularly consequential because it presents a specific medical-sounding equivalence without naming its basis. Without supporting evidence, readers cannot assess whether leg elevation helps in the situations described, applies only to some emergencies or could be unsuitable for a particular person. Bystanders should rely on emergency dispatchers and established first-aid guidance rather than treating the blog’s assertion as proven.

What the Blog Post Recommends
The source is a personal blog entry that republishes or summarizes a report with the title “Beyond the Med Speak: How to Save a Life.” It frames the recommendation around the possibility that many bystanders are unfamiliar with CPR or afraid to act. It then presents leg elevation as a low-effort alternative and describes it as harmless.
Those statements are the blog’s claims, not independently established findings in the material provided. The post does not give a publication date for any supporting research, link to a clinical trial or guideline, or distinguish among causes of collapse. That leaves readers without the information needed to judge when the proposed action might be appropriate.
““Bend down, pick up their feet, and hold their legs in the air waist-high.””

Evidence Behind Leg Elevation
The supplied source does not show whether leg elevation improves survival, restores a heartbeat or makes CPR more effective. It also does not identify the emergencies or patients for which the action is meant, or support its claim that the maneuver cannot cause harm. The author’s medical qualifications and the source of the blood-volume comparison are not provided.
As a result, the recommendation’s effectiveness and safety cannot be established from this report. The advice should not be used to delay a call to emergency services or steps advised by a dispatcher.
Follow Emergency Dispatch Guidance
If someone collapses, call your local emergency number and follow the dispatcher’s instructions. If the person is unresponsive and not breathing normally, the dispatcher can guide you through CPR; use an AED if one is available and follow its prompts. People who want to be better prepared can take an in-person CPR and first-aid course from a recognized provider.
The blog post itself names no follow-up research, guideline review or medical organization responding to its claims. Until reliable evidence or an authoritative first-aid recommendation is available, readers should treat its leg-elevation advice as unverified.
Key Questions
Does the post prove that raising someone’s legs can save their life?
No. It makes that suggestion but provides no cited clinical evidence showing that leg elevation saves lives.
Is raising the legs a replacement for CPR?
The post does not establish that it is. Follow the emergency dispatcher’s instructions; do not let an unverified suggestion delay CPR or AED use when directed or indicated.
What should I do if someone collapses?
Call your local emergency number and follow the dispatcher’s guidance. They can advise you on checking the person and taking appropriate steps, including CPR or using an AED.
Where did the claim about two units of blood come from?
The blog post does not cite a study, guideline or other source for its comparison, so its basis is unclear.
