![]() ![]() Further, the benefit over COT has been questioned. However, it can be poorly tolerated due to a tight-fitting interface (most commonly oronasal) which is uncomfortable, prone to leakage, and can result in nasal trauma. NIV can deliver the same physiologic effects of invasive mechanical ventilation thus preventing the associated risks of intubation including airway trauma, infections and the need for sedation. Though commonly used for acute respiratory failure, NIV and COT have limitations. ![]() This can be used in conjunction with or instead of conventional oxygen therapy (COT), including a simple face mask which delivers oxygen. ![]() Most commonly, it inflates the lungs by applying positive pressure to the airway. The most common method to treat this issue, non-invasive ventilation (NIV), is a form of mechanical ventilation that does not require a more invasive endotracheal tube. Oxygen and/or respiratory support are required for patients in emergency rooms, on the ward and/or in critical care settings during respiratory failure. ![]()
