Development of a random forest model for hypotension prediction after anesthesia induction for cardiac surgery

Figure 1 Research protocol flow chart. A total of 4504 patients who underwent cardiac surgery were screened for inclusion; 1474 were excluded. The 3030 who were eligible and included in the study were divided into a training set and a testing set. The random forest algorithm was applied to the training set for the modeling process and the parameters were debugged. The model was then validated in the test set.
