Nasal High-Frequency Ventilation.

Area of Science:

• Neonatal respiratory support
• Mechanical ventilation
• Pulmonary physiology

Background:

• Nonconventional ventilation techniques like NHFOV and NHFPV are emerging for neonatal care.
• Understanding the underlying physiology and mechanics is crucial for their effective application.

Purpose of the Study:

• To provide a comprehensive review of the physiology, mechanics, and biology of NHFOV and NHFPV.
• To conduct a meta-analysis of clinical trials involving NHFOV.
• To propose clinical guidelines and protocols for NHFOV use in neonates.

Main Methods:

• Literature review of NHFOV and NHFPV.
• Meta-analysis of existing clinical trials on NHFOV.
• Development of a physiology-based clinical protocol for NHFOV.

Main Results:

• NHFOV has a broader clinical evidence base compared to NHFPV.
• The meta-analysis provides insights into the efficacy of NHFOV.
• Suggested ventilatory parameter ranges and a clinical protocol are presented.

Conclusions:

• NHFOV and NHFPV are valuable nonconventional ventilation strategies for select neonatal patients.
• Evidence supports the use of NHFOV, with proposed guidelines enhancing its clinical application.
