A post on Book of Joe recommends raising a person’s legs as a way to help during a circulatory emergency, but it supplies no clinical evidence for its claims. Leg elevation is not a substitute for calling emergency services, following dispatcher instructions or starting CPR when indicated.
A Book of Joe blog post published in October 2026 says bystanders without CPR training can help someone in a circulatory crisis by lifting the person’s legs, but it offers no supporting clinical evidence for its claims and does not establish leg elevation as a replacement for CPR or emergency care. In a suspected cardiac arrest, the immediate priority is to contact emergency services and follow the dispatcher’s instructions.
The post recommends bending down, lifting the person’s feet and holding the legs around waist height. Its author claims the position increases blood return toward the heart and lungs and may help restore a heartbeat. Those explanations are claims made in the post, not findings substantiated by evidence included in the source material.
The blog also compares leg elevation to a transfusion of two units of blood, which it says represents 40% of an average adult’s circulating blood volume. It provides no study, calculation method or clinical reference for that comparison. Its assertion that the maneuver “can’t do any harm” is likewise unsupported in the material provided and should not be treated as a general safety guarantee.
The author says raising the legs is the first instruction given on arriving at a “Code Blue” scene. The post does not identify the setting, explain the patient’s condition or specify whether this is an established protocol. A personal practice described in a blog post does not, on its own, demonstrate accepted emergency-care guidance.
Why Leg Lifting Is Not CPR
The distinction matters because a person who is unresponsive and not breathing normally may be in cardiac arrest, a time-critical emergency. A reader who treats leg elevation as a stand-alone rescue technique could delay calling for help or beginning the response recommended by emergency professionals. The post’s reassuring wording may make the maneuver sound safer and more effective than the source material can establish.
People who do not know CPR can still take practical steps: call emergency services, put the phone on speaker, follow the dispatcher’s directions and ask someone nearby to get an automated external defibrillator (AED), if one is available. Dispatchers can guide callers through the next steps. CPR and AED use are skills people can learn through recognized training; a blog tip is not a substitute for that instruction.
Leg position may be relevant in some medical situations, but the post does not define which conditions it means or when raising the legs could be inappropriate. The safest response depends on what is happening and the person’s condition. Emergency dispatchers and trained responders are better placed to give case-specific directions.
What the Source Does Not Establish
The source is a personal blog post, not a clinical guideline or research report. It argues that few people know or perform CPR and presents leg elevation as a simple alternative. The supplied material gives no data to support its statement about how many people know CPR or act during emergencies.
It also does not cite medical organizations, studies or published protocols. That leaves its claims about increased blood return, a transfusion-equivalent effect and improved CPR effectiveness unverified within the source. No independent expert comments or official guidance were provided alongside the post, so this report cannot establish whether leg elevation has a role in a particular emergency. Readers should not infer that it replaces CPR, emergency calls or professional care.
““Bend down, pick up their feet, and hold their legs in the air waist-high.””

Evidence and Safety Questions
The source does not say what medical condition the suggested maneuver is intended for, how long to hold the legs up or what to do if the person has an injury or another condition that affects safe movement. It provides no research to verify the claimed circulation benefit or the comparison with a blood transfusion. The author’s qualifications and the circumstances behind the “Code Blue” account are also not supplied.
As a result, it remains unclear whether the recommendation reflects a specific clinical practice or the author’s personal view. The material does not establish that leg elevation improves outcomes, is appropriate for cardiac arrest, or is harmless across different emergencies. Those points require reliable medical guidance beyond the post.
Callers Should Follow Dispatchers
The source reports no follow-up study, medical review or response from an emergency-care organization. Until reliable guidance addresses the specific claim, readers should treat it as unverified advice, not a proven way to save a life without CPR.
If someone collapses and is unresponsive, call the local emergency number immediately and follow the dispatcher’s instructions. If the person is not breathing normally, tell the dispatcher and follow their directions on CPR and AED use. Bystanders can also ask another person to meet responders or retrieve an AED. The immediate next step is to get professional help involved, rather than relying on leg elevation alone.
Key Questions
Can raising someone’s legs replace CPR?
No evidence in the source supports that. The blog post’s recommendation is not shown to replace CPR, emergency services or dispatcher instructions.
What should I do if someone collapses and is unresponsive?
Call emergency services and follow the dispatcher’s instructions. Tell them what you observe, including whether the person is breathing normally.
Does the post prove that leg elevation is harmless?
No. The statement that the maneuver cannot cause harm is an unsupported claim in the provided material; it gives no evidence or exceptions.
Is the blood-transfusion comparison supported?
The post compares leg elevation to two units of blood but cites no study or calculation to substantiate that comparison.
Can people help if they have never learned CPR?
Yes. They can call emergency services, use speakerphone and follow dispatcher guidance. They can also ask another bystander to locate an AED if one is available.
