Abstract
Acute dialysis catheters are non-cuffed, non-tunnelled catheters used for immediate vascular access. They are primarily used for acute renal failure in bed-bound patients and for short-term use in patients with malfunction of permanent access. Long-term use of acute catheters is not recommended, but does occur with acceptable infection rates in dialysis centers where tunnelled, cuffed catheters are not available. Most acute catheters are made of polyurethane, but silicone catheters are now available with larger lumen sizes capable of delivering blood flow rates over 300 ml/min. Acute catheters should be inserted in the internal jugular or femoral vein under ultrasound guidance to minimize complications. Subclavian catheters cause stenosis, thrombosis, and perforation of vessels. Intermittent catheter malfunction still occurs, particularly for left-sided internal jugular catheters and catheters placed in women. Blood flow may improve with lumen reversal, intraluminal t-PA, or guidewire exchange. Limiting duration of use and dressing catheter exit sites with dry gauze and antiseptic ointments can prevent catheter-related infections.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
