Assessing oral comprehension with an eye tracking based innovative device in critically ill patients and healthy volunteers: a cohort study.

Purpose: Communication of caregivers and relatives to patients is a major difficulty in intensive care units (ICU). Patient's comprehension capabilities are variable over time and traditional comprehension tests cannot be implemented. Our purpose was to evaluate an oral comprehension test adapted for its automatic implementation using eye-tracking technology among ICU patients.

Eye tracking communication with intubated critically ill patients: a proof-of-concept multicenter pilot study.

Background: Communication is essential to establish patient-caregivers relationship in the intensive care unit. Intubated patients are not able to speak because the tracheal tube prevents vocalization. Use of communication tools such as eye tracking device could improve communication with intubated patients.
