Fig. 1

Trajectories of RR, HR, and ROX. This figure shows the distinct trajectories of respiratory rate, heart rate, and respiratory rate-oxygenation from the first 72 h of ICU stays based on data of the eICU-CRD. Using the approach of group-based trajectory model, 5 respiratory rate trajectories were presented in (a), 5 heart rate trajectories were presented in (b), 4 respiratory rate-oxygenation trajectories were presented in (c).
