Performance of neonatal ventilators in volume targeted ventilation mode

Area of Science:

• Neonatal respiratory care
• Mechanical ventilation technology

Background:

• Volume targeted ventilation (VTV) is crucial for neonates.
• Understanding ventilator performance variability is essential for safe and effective VTV.

Purpose of the Study:

• To evaluate performance differences among four neonatal ventilators using VTV modes.
• To test the hypothesis that ventilator type influences VTV performance.

Main Methods:

• Four neonatal ventilators were assessed using a lung model.
• Measurements included peak pressure, inflation time, mean airway pressure (MAP), and volume delivery.
• Ventilators tested: Draeger Babylog 8000, SLE 5000, Stephanie, and V.I.P. Bird gold.

Main Results:

• Significant variations in peak pressure and MAP were observed between ventilators.
• The Stephanie and V.I.P. Bird ventilators delivered lower peak pressures and MAPs.
• Inflation times differed, with SLE and V.I.P. Bird showing shorter durations at 5 mL VTV.
• V.I.P. Bird exhibited less volume variability but delivered lower volumes than set.

Conclusions:

• Neonatal ventilator performance in VTV modes is not uniform across different types.
• Observed performance discrepancies may necessitate adjustments in clinical settings.
• Further research into ventilator-specific characteristics is warranted for optimizing neonatal respiratory support.
