The pneumatic high-frequency oscillation expectoration system adopts high-frequency chest wall oscillation (HFCWO) technology. Through the pulse oscillation signal sent by the host machine, the inflatable vest or half chest band can produce high-frequency oscillation repeatedly at high speed, which promotes relaxation, liquefaction and detachment of secretions in the deep respiratory tract and lung, and forms air flow in the airway for directional autonomous drainage.
Indication: Excessive sputum in the airway, viscous secretions, weak sputum expulsion, mechanical ventilation, COPD, atelectasis, pulmonary infection, bronchiectasis, cystic pulmonary fibrosis, pediatric pneumonia, and post-surgery recovery.
| Group | Day 1 Expectoration (g) | Day 2 Expectoration (g) | Day 3 Expectoration (g) |
|---|---|---|---|
| High-frequency oscillation | 43.97±9.62 | 49.20±12.54 | 48.07±10.25 |
| Traditional Vibration | 34.70±10.56 | 36.93±11.02 | 36.63±11.62 |
Conclusion: HFCWO system is superior to vibration expectoration instruments. It significantly reduces the workload of nursing staff and is highly effective for clinical promotion.
Cons: Potential physical damage with long-term use; requires patient strength.
Cons: Labor intensive; inconsistent frequency; surface level action only.
Cons: Heavy device; causes wrist injury; does not reduce nurse workload.
