Neonatal Ventilation: A Brief Review

DiscussionVentilation means the removal of CO 2 , but ventilators only provide inspiration because expiration is passive, except for high-frequency oscillatory (HFO) ventilation, where expiration is active.Practically, however, in some HFO ventilators, expiration is passive.Due to active expirations, CO 2 removal may be more prone to hypocarbia, which leads to periventricular leucomalacia (PVL).That is why we need frequent arterial blood gases (ABGs).Ventilation works on the T-piece principle.In HFO ventilation, where there are high rates and low volumes compared to dead space, molecular diffusion is the primary mechanism of gas exchange.The filtration effect is considered during ventilation, where 90% of mean arterial pressure (MAP) will be attenuated [3].Because of the low tidal volume, we usually use MAP more than conventional ventilation.Ventilators have components like compressors, which compress the gases to deliver adequate pressure, particularly Abstract When infants are incapable of achieving satisfactory gas exchange independently, the provision of respiratory assistance becomes imperative.For neonates exhibiting respiratory insufficiency, the utilization of mechanical ventilation plays a vital role in enhancing oxygenation and facilitating the elimination of carbon dioxide.While a majority of infants necessitate ventilation because of pulmonary issues particularly due to respiratory acidosis, there are also instances where other conditions, such as seizures, metabolic acidosis, and shock, contribute to the need for respiratory support.Each ventilation strategy is designed with the objective of bolstering the respiratory systems of infants while concurrently safeguarding both the lungs and the brain against potential damage.It is important to note that brain damage incurred is irreversible.In this concise overview, we will explore the fundamental aspects and provide an overview of ventilation, as well as touch upon a few concepts that are not commonly discussed.
