Study Overview
Brief Summary
This study investigates the short-term physiological effects of pressure rise time modulation during volume-guaranteed ventilation in neonates. Pressure rise time is an adjustable parameter that influences how quickly inspiratory pressure reaches the target level during mechanical ventilation.
In this study, different pressure rise time settings will be applied during volume-guaranteed ventilation, and their effects on respiratory parameters, gas exchange, and patient-ventilator interaction will be evaluated. The aim is to determine whether modulation of pressure rise time has measurable short-term physiological effects in ventilated neonates and to identify optimal ventilator settings that may improve respiratory support.
Detailed Description
Mechanical ventilation is frequently required in neonatal intensive care units, particularly for preterm infants with respiratory distress. Volume-guaranteed ventilation is commonly used because it helps maintain stable tidal volumes while minimizing ventilator-induced lung injury.
Pressure rise time is a ventilator parameter that determines how quickly inspiratory pressure reaches the target level at the beginning of each breath. Alterations in pressure rise time may influence inspiratory flow characteristics, patient-ventilator synchrony, and overall respiratory mechanics. However, limited data are available regarding the short-term physiological effects of pressure rise time modulation during volume-guaranteed ventilation in neonates.
The objective of this study is to evaluate the short-term physiological responses to different pressure rise time settings during volume-guaranteed ventilation in neonates receiving respiratory support in the neonatal intensive care unit. Respiratory parameters, ventilator measurements, and gas exchange indicators will be monitored while sequentially applying different pressure rise time settings.
The findings of this study may contribute to a better understanding of ventilator parameter optimization in neonatal respiratory care and may help guide clinicians in selecting ventilator settings that improve patient-ventilator interaction and respiratory stability.
