Abstract:
This randomized controlled study was conducted to compare the efficacy and safety of High frequency oscillatory ventilation (HFOV) and Synchronized intermittent mandatory ventilation (SIMV) in preterm neonates with hyaline membrane disease requiring ventilation. The ventilation strategy in both the groups included achieving optimal lung recruitment and targeted blood gases. 49 patients received HFOV and 61 SIMV. The baseline characteristics were similar in both the groups. HFOV group demonstrated better early oxygenation, enabled reduction in oxygenation index (OI) within 24 h of ventilation (difference in mean OI at 1, 6, and 24 h of ventilation: P=0.004 in HFOV, and 0.271 in SIMV group). Duration of hospital stay was shorter in HFOV group (P=0.003). The complication rate and survival were similar in two groups.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
