Visualisation of the pathway for diagnosing a suspected VAP in a UK NHS ICU. The coloured boxes in the pathway represent points at which the OMA platform could be used. The green box represents the optimal role for the device, based on the clinical interviews. Here, the OMA platform would be used as a rule-in diagnostic. The orange boxes represent alternative possible roles for the OMA platform, as part of the routine investigations of all eligible ICU patients (top of the pathway) and as a monitoring test in patients with a suspected VAP (bottom of the pathway)
