ResMed manufactures a range of ventilators; They are indicated for home and hospital use, and have the flexibility for use in various clinical scenarios to support patients with respiratory insufficiency and failure. Our ventilators can provide invasive or non-invasive ventilation: Noninvasive ventilation (NIV) is a form of mechanical ventilation where air is delivered to the patient through a mask or mouthpiece. Invasive ventilation is used when sufficient ventilation cannot be achieved using non-invasive methods; air is delivered through a tube inserted into the trachea either by intubation or tracheotomy.
