Medical ventilators provide breathing assistance for patients with the inability to do so. This diaphragm controlled, high-frequency oscillatory ventilator (HFOV) provides alternative mechanisms of oxygen exchange and is used in cases where critical care patients can’t breathe on their own. Delivery of breathable air is smaller and more frequent and generally meant for elderly adults and neonatal patients.
