After 12 hours on volume-control ventilation, what should the neonatal/pediatric specialist do if there is an increase in secretion viscosity?

When faced with an increase in secretion viscosity in a patient on volume-control ventilation, changing to a heated wick humidifier is an appropriate intervention. This method of humidification delivers optimal moisture and temperature to the inspired air, which can help to thin secretions, making them easier to clear. Maintaining adequate humidity is crucial in ventilated patients as it prevents the airways from becoming dry and encourages normal secretion properties.

Using a heated wick humidifier can enhance mucosal hydration, which is essential for maintaining normal airway function and reducing the likelihood of obstruction due to thickened secretions. This type of humidifier typically provides more effective humidification compared to passive humidification methods, especially in long-term ventilation scenarios.

While other options such as administering bronchodilators, suctioning frequently, or giving mucolytics may assist in managing thick secretions, they do not address the underlying issue of inadequate humidification that often contributes to increased secretion viscosity. Ensuring optimal humidity can be a more fundamental approach to preventing thick secretions in the first place.
