In the health field, new recommendations and methods of care are constantly evolving and sometimes difficult to implement. In order to try to implement them in the form of care protocols, in the context of early weaning of intubated patients ventilated in intensive care units, we will call upon the Sciences of Education to help us in this process and to accompany the change thanks to reference-actors from the field. We will call upon several authors to have an epistemological viewpoint, which we will put in tension with the double posture of the practitioner-researcher to carry out a research-intervention. The results of the exploratory monocentric survey reveal that the agitation of ventilated intubated patients induces anxiety in the caregivers. The weaning protocol and practices are not harmonized between the two rehabilitation units. One of the main avenues for action that the group of referring actors is considering is the implementation of a protocolized weaning tool to harmonize care practices in the two units for the benefit of patients and caregivers.
