Study Notes
Mechanical Ventilation in Neonatal Patients
- The main purpose of mechanical ventilation in neonatal patients with respiratory failure is to provide adequate gas exchange and minimize lung injury.
- Understanding pulmonary mechanics is important in using mechanical ventilation because it enables clinicians to tailor ventilation strategies to the individual patient's needs.
Development of Assisted Mechanical Ventilation
- The development of sophisticated modes of assisted mechanical ventilation in premature neonates has been enabled by advancements in technology and a better understanding of neonatal respiratory physiology.
Physiology-Based Approach
- A physiology-based approach is important in applying mechanical ventilation in neonatal patients because it allows clinicians to individualize ventilation strategies and avoid ventilator-induced lung injury.
Aim of Mechanical Ventilation
- The ultimate aim of providing adequate gas exchange and minimizing lung injury in neonates on mechanical ventilation is to promote lung growth and development.
Goal of Mechanical Ventilation
- The goal of mechanical ventilation in neonates is to support the patient's respiratory function until they can breathe spontaneously.
Volume-Targeted Ventilation
- Volume-targeted ventilation is favored in neonates over the last decade because it allows for more precise control of tidal volumes and helps to minimize lung injury.
Intrapleural Pressure
- In newborns, the intrapleural pressure decreases during inspiration due to the negative pressure generated by the diaphragm and intercostal muscles.
Respiratory Muscle Fatigue
- Newborns are at higher risk of respiratory muscle fatigue due to their immature respiratory muscles and high ventilatory demands.
Inspiratory Time
- In spontaneously breathing preterm neonates, the inspiratory time (i-time) is typically around 0.3-0.4 seconds.
