Mechanical ventilation is often very necessary in the care of critically ill pediatric patients. However, it comes with many different complications that include chronic lung disease, tissue damage, and ventilator-associated pneumonia. Over time, we have increased our understanding of how a child's physiology interacts with a ventilator and this has led to two different non-invasive forms of respiratory support: bilevel positive air pressure (BiPAP) and neurally adjusted ventilator assist (NAVA). While both modalities come with a lot of benefits such as improved gas exchange, decreased respiratory and heart rate and decreased inspiratory work of breathing, NAVA has the ability to provide synchronous ventilatory support due to the electrical activity of the diaphragm.
