New diagnostic technologies are changing the functional evaluation of respiratory disorders by integrating evaluation with traditional tests such as spirometry and plethysmography with the forced oscillation technique and ultrasound. The course aims to deepen the principles and the interpretation of the classic respiratory function tests integrated with the more innovative ones, but already available in the respiratory physiopathology laboratories. The ultimate goal of the course is to make early and accurate pneumological diagnoses and to take care of them with modern pharmacological and ventilatory support options.
