Impact of Physiotherapy Session in Cardiac Surgery Patients

This work consists, first of all, in making an inventory of the physiotherapy of the patient undergoing cardiac surgery under high flow oxygenation at the CHRU NANCY. Then, in a second step, the impact of the physiotherapy on the lung ultrasound score associated or not with the NIV of the patient under OHD after cardiac surgery will be studied. The objective is therefore to answer the following research question: what is the impact of a physiotherapy session with or without non-invasive ventilation in patients receiving high flow oxygenation after cardiac surgery on the lung ultrasound score measured by ultrasound? Main hypothesis: Physiotherapy is associated with NIV when it is prescribed in patients undergoing high flow oxygenation after cardiac surgery. Secondary hypothesis: Physiotherapy + NIV further improves pulmonary aeration versus physiotherapy + high flow oxygenation.
