Abstract: Highlights•Causal inference can help estimate causal effects, given the causal model is known.•Using Causal Inference, we aim to find the causal effect of oxygen therapy at ICU.•We leveraged observational data and expert knowledge to find underlying causal model.•We extracted cohort data from MIMIC-III database, a large public healthcare dataset.•Proposed causal method is suitable for exploring a broader set of clinical questions.
