Physiology of Body Lateralization on Regional Lung Ventilation Study

The participant will be guided to the Multicare bed and will be positioned supine with the headboard not tilted. At this point, the participant will already have the EIT electrode belt and head, trunk and lower limb cushions around it, providing stability. After the participant has been correctly positioned, ventilatory monitoring will begin using the EIT. The environment must be fully controlled, that is, with adequate lighting, all collection members in silence, as well as the devices in the place, air-conditioned environment, without exposing the participant to heat or cold. Before starting the collection, the volunteer will be asked to try not to sleep or talk, making it clear that any discomfort can be reported at any time. To keep the volunteer awake, visual and sound stimuli can be performed. Furthermore, if you cough or sigh, the collection will restart. The intervention will last 5 minutes and will be repeated twice, with intervals between body lateralization.

The participant will start from the bench press to the 30-degree lateral position. The cushions placed at the beginning of the collection will provide stability so that the inclination does not compromise the correct positioning of the participant, preventing them from sliding on the bed. Furthermore, it is also a safety measure for the participant. The environment will be controlled throughout the intervention and visual and sound effects will also be performed in lateral positioning. The volunteer will remain in this position for five minutes and shortly after will be placed in the supine position again. To start the protocol for the second and final time, the participant will have a washout time of thirty minutes.
