This invention can be used in three different ways for patients who are lying down in bed or on the operating table. First it facilitates the endotracheal intubation, secondly it facilitates the spontaneous breathing of obese patients and thirdly it assists the spontaneous inspiration and expiration in a non-invasive way. This invention device is positioned under the patient before he is asleep without disturbing him. It allows a gradual elevation of the lower and or upper thorax, a gradual elevation of the head giving a flexion of the neck and a gradual hyperextension of the head. After intubation the position is returned to normal without need for removing the invention device. This invention elevates the spinal column and therefore the thorax is no more compressed and the ribs can move free. Inspiration requires less force and the patient can be breathing easier even when lying down. In this invention the spinal column elevation can also be inflated in a synchronized way with the respiration of the patient. During inspiration the spinal column is elevated, facilitating the inspiration. During expiration the elevation is lowered, facilitating the expiration. The work of breathing is reduced for the patient resulting in larger minute volume ventilation or less oxygen consumption.
