Brief Summary

A weaning trial is a test that simulates physiological respiratory conditions after extubation in order to assess the patient's ability to breathe without the assistance of a ventilator. This test is highly susceptible to induce dyspnea, with 62% of patients reporting a dyspnea score on VAS greater than 3. Similarly, the prevalence of anxiety is high during weaning trials. 60% of patients treated in a respiratory weaning unit report psychological symptoms. Dyspnea can be a traumatic experience for patients. In intensive care, up to half of patients suffer from dyspnea, which is described by patients as one of the worst memories of their stay in intensive care. The virtual reality headset is a device that simulates a realistic, three-dimensional environment, allowing the patient to be totally immersed, so that they feel as if they are really present in a virtual world. This environment can be combined with hypnotic verbal support. The research hypothesis is that virtual reality during a spontaneous breathing trial would relieve the respiratory discomfort induced by the weaning trial. The secondary hypotheses are that virtual reality could reduce the anxiety associated with spontaneous breathing trials. These benefits could be associated to a reduction in ventilatory drive. To assess dyspnea a VAS scale will be used, as the MV-RDOS scale, and the amplitude of EMG activity of inspiratory muscles.

Outcome Measures

Primary Outcomes (1)

  • Respiratory discomfort VAS

    The primary endpoint is the comparison of the respiratory discomfort VAS between the intervention group (VR) and the control group (standard care) at the end of the ventilatory weaning test. Scale values:0-10, higher scores mean a worse outcome.

    At inclusion (day1)

Secondary Outcomes (5)

  • Effect of IVR on anxiety intensity at the end of the withdrawal test

    At inclusion (day1)

  • Evaluation of the effect of virtual reality on respiratory discomfort assessed by the MV-RDOS (Mechanical Ventilation-Respiratory Distress Observation) score

    At inclusion (day1)

  • Evaluation of the effect of virtual reality on respiratory drive assessed by the P 0.1, and EMG of scalene and parasternal muscle

    At inclusion (day1)

  • Description of the effect of virtual reality on respiratory rate and heart rate

    At inclusion (day1)

  • Evaluation of the tolerance of virtual reality.

Study Arms (2)

Immersive virtual reality in patient with VAS dyspnea ≥ 3

EXPERIMENTAL

Once included in the study, the patient will undergo a 15-minute session of mechanical ventilation followed by a 15-minute weaning trial without intervention (control period). A respiratory discomfort VAS is performed following the spontaneous breathing trial. If the VAS is ≥ 3 cm, the patient is randomised between the intervention group (immersive virtual reality) and the control group (standard care). The spontaneous breathing trial will be continued for a further 15 minutes in accordance with usual management, with one of the two interventions according to randomisation.

Interventions

The virtual reality headset is a device that simulates a realistic, three-dimensional environment, allowing the patient to be totally immersed, so that they feel as if they are really present in a virtual world. This environment can be combined with hypnotic verbal support. Virtual reality will be achieved using a virtual reality headset (GAMIDA®, Pico G2 4K, France) and audio headphones with noise reduction (Bose® Quiet Comfort 35 II, France). A tablet (Samsung® Galaxy Tab A 2019, 4G / Lenovo M8, France) equipped with Healthy Mind software will enable patients to enjoy a 360° visual and auditory 3D experience via a Bluetooth connection.
