High frequency oscillatory ventilation in children and infants
1Dept of Child Health, King's College Hospital, London, UK.
Summary
High frequency oscillatory ventilation (HFOV) improves oxygenation in infants and children with lung disease. Early HFOV use can prevent chronic lung disease and reduce the need for extracorporeal membrane oxygenation.
Area of Science:
- Pediatric critical care medicine
- Respiratory physiology
- Mechanical ventilation
Background:
- High frequency oscillatory ventilation (HFOV) utilizes 5-15 Hz frequencies with active inspiratory and expiratory phases.
- While general HFOV principles apply across devices, variations in waveform and mechanical efficiency exist.
- A high volume strategy is beneficial for improving oxygenation in pediatric patients with diffuse alveolar disease.
Purpose of the Study:
- To evaluate the efficacy of HFOV in pediatric patients with severe lung disease.
- To assess the impact of HFOV on oxygenation and the need for alternative respiratory support.
- To determine HFOV's role in preventing chronic lung disease and reducing extracorporeal membrane oxygenation (ECMO) requirements in neonates.
Main Methods:
- Application of HFOV with a high volume strategy in pediatric and neonatal populations.
- Monitoring oxygenation response within the initial 6 hours of HFOV initiation.
- Comparison of outcomes including chronic oxygen dependency, need for ECMO, and incidence of chronic lung disease.
Main Results:
- A high volume strategy with HFOV improves oxygenation in children and infants with diffuse alveolar disease.
- Early improvement in oxygenation predicts a favorable outcome; lack of improvement after 6 hours suggests considering alternative strategies.
- HFOV effectively supports children with severe lung disease, reducing chronic oxygen dependency.
- In near-term and term infants, HFOV decreases the need for ECMO.
- Appropriate HFOV use in premature infants reduces the incidence of chronic lung disease.
Conclusions:
- HFOV is an effective ventilation strategy for pediatric patients with severe lung disease, including diffuse alveolar disease and conditions requiring ECMO.
- Timely initiation and assessment of HFOV response are crucial for optimizing patient outcomes and preventing long-term respiratory complications.
- HFOV plays a significant role in reducing chronic lung disease and the need for advanced respiratory support in neonates.

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:29Mechanical Ventilation I: Indication and Settings
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
