Dyspnea Facial Recognition During Weaning

"The visible and infrared cameras will be positioned in front of the patient (150 cm from the patient's face). EMG electrodes will also be placed on the wings of the nose and the parasternal intercostal muscles. The pressure and flow sensors will finally be positioned at the level of the airways. EMG, respiratory and video recording will begin 15 minutes before the start of the ventilatory weaning trial. Just before the weaning test, a measurement of dyspnea will be carried out. After 15 minutes of baseline recording, patients will be placed in a ventilatory bondage test. Dyspnea will be measured every 5 minutes during the weaning test. After 30 minutes of testing, the ventilatory weaning test is stopped. Patients will then be placed on ventilatory assistance with the same parameters used before the weaning test. An additional 15-minute recording after the end of the ventilatory weaning test will also be made. The recording will therefore last 1 hour in total"
