Mechanical Inhalation Exhalation Technique (MIE) - Simulating Physiological Cough
Mechanical inspiratory expiratory expectoration (MIE) technique, with positive and negative pressure switching to assist in amplifying cough effects, effectively increases cough peak flow velocity, and drives secretion transfer from the periphery to the central airway.
Airflow oscillation, loosening small airways and alveoli to retain sputum in pigs, assisting in the movement of sputum with exhaled airflow.
Coughing is the most fundamental physiological mechanism for clearing airway secretions. Non invasive cough machines use mechanical aspiration exhalation (MIE) technology to completely mimic the movement of the respiratory system during coughing, alternating between positive pressure support and negative pressure suction. During the inhalation phase, positive pressure is generated in the airway, causing the lungs to dilate and releasing secretions and clots in the airway, which then switches to the negative pressure exhalation phase, pushing secretions towards the greater airway and effectively clearing respiratory secretions.
