Rotary HFO/IMV Ventilator for Infant and Adult Fighting Disease with Electronics

HFOv is expanded into adult field Comparison of CMV and HFO pressure wave form This figure compares CMV and HFO pressure wave forms at the same mean airway pressure (MAP). The HFO pressure waves are sinusoidal and symmetrical with respect to the MAP axis. Upon entering the trachea after passing through the endotracheal tube, the amplitude of sinusoidal wave is attenuated drastically at the periphery of the airways near the pulmonary alveoli. Thus, at a given MAP, HFO can be expected to cause much less physical damage to pulmonary alveoli than would be the case with CMV.

Three mode, One touch selection High Frequency Oscillation(HFO) Ventilation permits sufficient and sustained exchange of gas via ventilation of which stroke volume (tidal volume) is smaller than volume of anatomical dead space. HFOV technology has long been established in neonatal field and the following merits are well • Smaller pressure fluctuation within thoracic cavity reduces danger of tracheobronchial injury. • Smaller pressure fluctuation in alveoli gives less variation of blood pressure and intracranial pressure. Newly developed rotary valve alternates air way to the membrane chamber...
