Simple CPAP (SIMPAP) for Neonatal Transport—Device Development and Proof of Concept Study
Bibliographic record
Abstract
Objective: To develop a low-cost, easy to use CPAP device with a simple patient interface—SIMPAP. Design: This was an in vitro experimental study. SIMPAP was designed and developed over three iterations to be able to use in clinical studies. SIMPAP consists of intersecting cylinders with each opening performing a designated function. One of the openings serves as an extremely short expiratory limb that is fitted with a calibrated occlusion. This results in a nonrebreathing system that generates predetermined pressure against which the baby has to exhale. Main Outcome Measure: To analyze the pressures generated by the initial prototypes of the SIMPAP device. Results: Four SIMPAP bodies and four pressure relief valves were tested with different combinations as four exercises. Mean (–2Sd to +2SD) pressure generated at a flow rate of 1 liter was 3.4 (2.2-4.7) cm of H 2 O and at 2 liters per min flow was 5.7 (4.8-6.6) cm of H 2 O. The 95% limit of agreement between exercises 1 and 2 was –0.4 to +1 cm of H 2 O, and between exercises 1 and 3 and 1 and 4 was –1 to +1 cm of H 2 O across the pressure range. Conclusion: SIMPAP can deliver therapeutic CPAP at low gas flow rates. Further clinical studies are warranted to establish the efficacy and safety of this new device on neonates.

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; a candidate call from one teacher head, not a consensus.
