vitaldb-ioh@0 · binary · primary metric: auroc · spec hash ed8c557f5d0a

Hypotension is mean arterial pressure below 65 mmHg for at least 60 s within the 5 minutes after a 5-minute input window (numeric MAP every 2 s). Windows are split by patient; scores are on the test split, with 95% intervals from a bootstrap over patients.
