Ethical approval for this study (Ethical Committee number: 1440) was provided by the Ethical Committee of Chiba Emergency Medical Center on March 11, 2022. The study was registered before patient enrollment at the UMIN (University Hospital Information Network) Clinical Registry: (UMIN000047793; principal investigator: Azusa Inada, date of registration: May 18, 2022, website: https://center6.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000054491). Contact information for the full trial information is available on the UMIN website. Because of the safe noncontact feature of the BSS, measurements were started immediately after ICU admission. The investigators fully explained the aim and potential risks of the study to each patient or the patient’s relatives at the appropriate time. Only data of patients for whom written informed consent was obtained from the patients or their relatives were used in this study."
