Feasibility of continuous non-invasive finger blood pressure monitoring in adult patients admitted to an intensive care unit: A retrospective cohort study

•Continuous blood pressure monitoring ensures timely recognition of hypotensive events in the intensive care unit.•Non-invasive finger blood pressure monitors using finger cuffs could serve as an alternative for invasive arterial catheters if a finger blood pressure signal can be obtained.•Finger blood pressure signals were obtained in 94% of adult intensive care unit patients.•Patients unsuitable for continuous non-invasive blood pressure monitoring could not be identified based on patient characteristics generally available upon admission.
