Hypothesis
Does spontaneous breathing during pressure-controlled ventilation improve oxygenation and lung function in different models of acute lung injury?
Conclusion
Spontaneous breathing improves oxygenation, reduces shunt fraction, and increases end-expiratory lung volume in both models of acute lung injury.
Supporting Evidence
- Spontaneous breathing during pressure-controlled ventilation improved oxygenation in both models of lung injury.
- End-expiratory lung volume was significantly higher with spontaneous breathing.
- Shunt fraction decreased with spontaneous breathing in both models.
Takeaway
Letting pigs breathe on their own while getting treated for lung injury helps their lungs work better and get more oxygen.
Methodology
Forty-four pigs were randomly assigned to two models of acute lung injury and ventilated with or without spontaneous breathing, with measurements taken at baseline and after treatment.
Limitations
The study was conducted in animal models, which may not fully replicate human responses.
Participant Demographics
Pigs used in the study.
