Continuous airflow measurements during anesthesia monitoring, intensive care treatment as well as in clinical and ambulatory environments provide important information for the assessment of cardiorespiratory and breathing circuit behavior and have become indispensable in modern medicine. 90 years after the first use of the iron lung, we are now dealing with mechanical ventilation systems that supply the patient with breathing gas by means of mechanical “air pumps”. This ventilation technique uses positive pressure to deliver air to the patient’s lungs. The increase of intelligent features incorporated into these ventilators, allow them to automatically adapt to changes in lung function or patient breathing.
