ventilator
Pronunciation: VEN-tl-ay-ter
Mechanical device that assists or replaces spontaneous breathing in neonates with respiratory failure.
Full Definition
A neonatal ventilator is a life-support machine designed specifically to provide mechanical ventilation for newborns and infants with respiratory insufficiency or failure. These devices deliver precise volumes of gas mixture at controlled pressures and rates, accommodating the unique physiology of immature lungs. Modern neonatal ventilators offer various modes including conventional mechanical ventilation, high-frequency oscillatory ventilation, and synchronized intermittent mandatory ventilation. They feature sophisticated monitoring capabilities and safety alarms to prevent barotrauma and optimize gas exchange while minimizing lung injury in vulnerable preterm infants.
Usage
Usage note: Always specify ventilation mode and key parameters in documentation. Avoid confusion with personal protective equipment respirators.
In Context
- "The ventilator settings were adjusted to SIMV mode with a rate of 25 breaths per minute." — Respiratory therapy note
- "Weaning from the ventilator began once spontaneous respiratory efforts improved." — Progress note
