Safety of Long Distance Aeromedical Transport of the Cardiac Patient
Bibliographic record
Abstract
Although long distance aeromedical transport of cardiac patients occurs with increasing frequency, data regarding the incidence of complications are lacking and guidelines for air ambulance transport are nonexistent. The purpose of this thesis is to evaluate the safety of long distance aeromedical transport of cardiac patients, and to recommend a time frame for air ambulance transport of patients post myocardial infarction. An analysis of all long distance aeromedical transports performed by Montreal-based Skyservice Lifeguard from 9811/1 to 98110/1 is presented. 109 cardiac patients were transported; 83 by air ambulance and 26 commercially. All inflight complications were minor and resolved quickly. After analysis of the results, it is concluded that air ambulance transport of cardiac patients can safely be performed earlier than guidelines for commercial flights. Air ambulance transport appears safe post complicated myocardial infarction by day 7 or >72 hours chest pain free, and post uncomplicated myocardial infarction by day 3 or >48 hours chest pain free. Future guidelines for aeromedical transport of patients post myocardial infarction should distinguish between air ambulance and commercial flights.

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.
