What Is Your KVO? Historical Perspectives, Review of Evidence, and a Survey About an Often Overlooked Nursing Practice
Bibliographic record
Abstract
Like many nursing "sacred cows," the practice of keeping a vein open with a small infusion of intravenous solution does not have clear origins or robust evidence. A survey of Canadian nurses was conducted to determine current practices. More than 50% of respondents reported regularly using a keep-vein-open (KVO) rate between doses of intermittent medication. Frequently, the rate was not specified by the prescriber; in this case, nurses preferred 21 to 30 mL/h. Given the absence of evidence and the frequent use, it is important to ensure that KVO is used properly in the context of a medical prescription or an organizational protocol.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
