Abstract: A method for ventilating the lungs of a patient. The method includes a smart tube for intubation comprising a tip and a cuff. The method also includes one or more cameras, coupled with the smart tube, for providing relative positional intubation measurements of the patient and/or providing intubation images of the patient. Further, the method includes one or more sensors, coupled with the smart tube, for sensing the inflation of the cuff and/or sensing pressure of the cuff. The method for ventilating additionally includes a computing method, coupled with the camera, the at least one sensor and the smart tube, for computing programmed feedback based on the relative positional intubation measurements, and/or the intubation images, and/or the inflation of the cuff, and/or the pressure of the cuff.
