Screening algorithm. Natural language processing (NLP)–based transfusion-related acute lung injury (TRALI) screening algorithm. Asterisk indicates that, in the absence of a Pao2:Fio2 ratio, surrogate markers of hypoxemia used in order of availability were Pao2 ≤117 mmHg followed by Spo2 ≤97%. CXR = chest radiograph; plus sign (+) = positive.
