This randomized controlled trial evaluated the effects of an Asepto syringe versus an incentive spirometer (IS) on lung function in 24 healthy volunteers. The three-ball IS produced the highest tidal volume (Vt) of 1868 mL, significantly outperforming the Asepto syringe at 1264 mL (p < 0.0001).
Key findings
- Three-ball IS produced the highest tidal volume (Vt) of 1868 mL.
- Asepto syringe achieved a Vt of 1264 mL, significantly lower than the three-ball IS.
- One- and two-ball IS improved end-expiratory lung volume (EELV) significantly.
- All devices increased dorsal ventilation compared to baseline (p = 0.048).
Why it matters
Understanding the effectiveness of different devices for lung expansion can inform clinical practice, particularly in settings where promoting lung function is critical for patient recovery and management.
