Term interpretation:

Respiratory Distress Syndrome (RDS) premature infants are prone to develop RDS due to incomplete lung development. NIV may provide Continuous Positive Airway Pressure (CPAP) or bi-level positive airway pressure (BiPAP), helping to keep the alveoli open and improve oxygenation.

Transient dyspnea (TTN) TTN may occur in neonates after birth due to incomplete pulmonary fluid absorption. NIV can provide the necessary respiratory support to help newborns smoothly pass this stage.

Bronchopulmonary dysplasia (BPD) prolonged use of mechanical ventilation and high concentrations of oxygen may lead to BPD. NIV, as a non-invasive means, can reduce the associated risk of mechanical ventilation and promote lung development.

Obstructive Sleep Apnea (OSA) for neonates with OSA, NIV can improve respiratory quality by providing positive airway pressure, preventing airway collapse.

The advantages of non-invasive assisted ventilation 1. Reduced invasive procedures-NIV does not require intubation, reducing the risk of intubation-related complications such as infection, airway damage, and bronchopulmonary dysplasia. 2. The comfort level is improved, namely, the comfort level of the neonate can be improved by using equipment such as a nose cover or a nose plug, and the pain and discomfort caused by intubation are reduced. 3. The lung tissue is protected, the positive airway pressure provided by NIV can effectively prevent alveolus collapse, reduce lung injury and is beneficial to the protection and recovery of the lung tissue. 4. The NIV equipment is easy to operate and manage, and nursing staff can monitor and adjust ventilation parameters more conveniently, so that nursing efficiency is improved.

The clinical effect of noninvasive assisted ventilation is 1. Improve oxygenation NIV can provide continuous positive airway pressure, improve oxygenation state, improve blood oxygen saturation and help neonate recover faster. 2. NIV can effectively reduce the respiratory work of newborns and lighten the respiratory burden by reducing the respiratory resistance and increasing the alveolar ventilation. 3. Reducing complications, such as pneumonia, pneumothorax, bronchopulmonary dysplasia, etc. caused by trachea cannula can be reduced by using NIV.

The application of the noninvasive auxiliary ventilation in the neonates provides a safe and effective respiratory support means for premature infants and neonates suffering from respiratory diseases. NIV helps improve neonatal respiratory status and clinical outcome by reducing invasive procedures and complications, improving quality of life.
