Q: What is the biggest advantage of applying BiPAP (non-invasive positive pressure ventilation) via standard type of ventilators?


Answer: Standard type of ventilators by default have separate inspiratory and expiratory tubing which minimizes the rebreathing of carbon dioxide. Also, more reliable and precise concentration of oxygen can be delivered.
