Hemopump
Open-knowledge reference entry
The Hemopump was designed to allow for temporary support of a failing heart. It is a continuous flow pump, and does not need to be synced to the rhythm of the heart. It assists in temporary heart stimulation with conditions such as cardiogenic shock following acute myocardial infarction, heart failure from cardiopulmonary bypass, and more. The pump can continually monitor the left ventricle, which allows for perpetual observation of the hearts condition. This allows for any necessary changes to be made when needed. The pump operates at speeds between two hundred and ninety and four hundred and seventy revolutions per minute.
The Hemopump Cardiac Assist System is an older design intra-arterial, axial-flow pump circulatory assist device concept that offers temporary left ventricular support to patients in refractory cardiogenic shock without requiring major surgery for insertion.
The Hemopump draws blood with the impeller from the left ventricle and then exchanges it through the aorta. It can run at a constant speed, or two variable speeds during the cardiac cycle. Volume of the stroke, the rotating speed, or the pressure can all be tuned.
This brief starts where responsible research should: with the source description of “Hemopump” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 12, 2024. The linked authority identifier is Q5712539. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
