Table 3 Intraoperative hypotension and triple low state exposure associated with TVI patterns

From: The triple variable index combines information generated over time from common monitoring variables to identify patients expressing distinct patterns of intraoperative physiology

Table 3, Proportions of total profiles that experienced intraoperative hypotension (IOH) and triple low state (TLS) exposure for each pattern. Median rates of data capture for MAP and TVI values are shown. Q1 1st quartile, Q3 3rd quartile, hr hour
