TL;DR
A 2026 blog post claims that raising a collapsed person’s legs can help restore circulation and make CPR more effective. The source provides no supporting evidence for its comparison to a blood transfusion, and leg elevation is not a substitute for CPR or emergency services.
A blog post published in October 2026 advises bystanders who do not know CPR to raise a collapsed person’s legs, claiming this may increase blood return to the heart. The post does not cite evidence for that claim or establish that leg elevation can replace CPR or emergency medical care.
The article on bookofjoe2.blogspot.com says to bend down, lift the person’s feet and hold their legs around waist height. It presents the action as a simple step for an untrained, frightened bystander, and claims that moving blood from the limbs toward the heart and lungs could help restore a heartbeat.
The post also says leg elevation is equivalent to transfusing two units of blood, which it describes as 40% of an average adult’s circulating blood volume, and says the maneuver makes CPR more effective. It offers no study, medical guidance or other source for these statements. Its author says this is the first instruction given on arriving at a “Code Blue” scene, but provides no details that would verify that account.
Why Emergency Guidance Matters
The post addresses a real concern: a bystander may hesitate when someone collapses because they have not learned CPR. But confident-sounding advice can shape decisions in an emergency. Presenting leg elevation as a way to save someone without CPR risks leaving readers with the impression that it is an adequate response to a life-threatening event.
The article itself says leg elevation may make CPR more effective, which does not support using the maneuver instead of CPR. Readers should distinguish the post’s claims from established emergency instructions and contact local emergency services when someone is unresponsive or in immediate danger.

The Claim and Its Limits
The source is a personal blog post titled “How to save a life without knowing CPR.” It frames its advice around the view that few people know what to do during an emergency, then offers raised legs as a practical action. It does not identify a clinical guideline, research paper or emergency-response organization as the basis for its recommendation.
The report also does not specify what kind of collapse or circulatory problem it means, or whether the person is breathing normally. Those details matter to emergency response. The post’s explanation about blood returning to the heart and its numerical comparison to a transfusion should therefore be treated as claims made by the author, not verified medical facts.

Evidence Behind Leg Elevation
The post does not provide evidence that raising a person’s legs restores a heartbeat, equals a two-unit blood transfusion, or improves CPR outcomes. It does not state whether the recommendation applies to every collapse or identify exceptions. No outside medical source is included in the supplied material, so the claims cannot be verified from it.
It is also unclear who wrote the post, what qualifications the author has, or what “Code Blue” setting the author refers to. The source does not report a new study, policy change or formal medical recommendation; it is an advice article.

Use Established Emergency Steps
The source describes no planned follow-up or next milestone. For readers, the immediate next step is to learn CPR and first aid through a recognized local course and to follow instructions from emergency dispatchers during an incident. If someone collapses and is unresponsive, call the local emergency number and follow the dispatcher’s guidance; do not rely on a blog post’s leg-raising advice as a replacement for emergency response.

Key Questions
What does the blog post recommend?
It recommends lifting a collapsed person’s legs to about waist height, claiming this may increase blood return toward the heart.
Does the source show that leg elevation can replace CPR?
No. It provides no evidence that leg elevation can replace CPR. It says the maneuver makes CPR more effective, but does not support that claim with a cited source.
Is the post’s comparison to a blood transfusion verified?
The post claims raised legs are equivalent to transfusing two units of blood, or 40% of an average adult’s circulating blood volume. It cites no evidence for that comparison.
What should a bystander do if someone collapses?
Call the local emergency number and follow the dispatcher’s instructions. The source material does not provide a verified emergency-response protocol, so readers should not treat its advice as a substitute for professional guidance.
