a The diagnosis after POC-US is the initial diagnosis for group 1 (G1) and the intermediate diagnosis for group 2 (G2), the diagnosis after standard protocol is the initial diagnosis for G2. AHF, acute heart failure; ECOPD, exacerbation of chronic obstructive pulmonary disease; ARDS, acute respiratory distress syndrome.
