Benefits of Sigh Breaths on HFOV
- Sigh breaths during high-frequency oscillatory ventilation (HFOV) increase end-expiratory lung volume, especially in dependent lung regions.
- They improve oxygenation without significantly altering mean airway pressure, showing promising physiological benefits.
EIT as a Lung Monitoring Tool
- Electrical impedance tomography (EIT) enables non-invasive, bedside monitoring of regional lung volume changes in preterm infants.
- This tool provides detailed lung aeration visuals useful for assessing ventilation strategies like sigh breaths.
Use Intermittent Sigh Breaths Carefully
- Consider using intermittent sigh breaths three times per minute with a one-second inspiratory time during HFOV to facilitate lung recruitment.
- Balance the benefits with caution as safety and long-term outcomes are not yet well studied.
